Has anyone or does anyone know how to convert their manual heat and air to an automatic climate control system?

Thanks,

Leon

come on guys he's new here. go easy on him. and to answer the question...yes it can be done and i think one guy has done it on here with pics and a parts list of everything you'll need. just go to the search button at the top of the page and type what youre looking for. if you can't find it then post a thread. otherwise some guys get cranky about the rerun threads.


here's the thread: Change Manual a/c heater to Auto digital

Wasn't someone selling the whole kit required to do this in classifieds? $900 IIRC

OK, well, I don't want to berate the OP or anything, but to me this is a very "iffy" type mod. Not actually sure what the real appeal to doing this is since auto-climate controls seem much more frustrating than the manual ones. But I guess to each his/her own. Just saying, there are probably at least 25 to 30 other mods that would be well worth doing before this one. Is there anything in particular you're really looking to get from doing this mod?

i think its just for the "fanciness" of it or something...to me, theres nothing appealing about an auto AC....ive had two cars with it (corvette and mercedes) and we always had them on manual anywya, cause down here its always full blast or off....but then again, i prefer my 100 buck tom tom GPS that i can manipulate while driving, update whenver i need to for free etc over adding a 1000 buck OEM or afermarket navi unit....

Not to mention you can transfer it into another vehicle using just your pocket. Seriously, the in car nav units are ridiculously overpriced for what they are right now. Why so much extra for the nav functionality?

exactly. and my Tom Tom responds much quicker and heck mine has red light camera warnings and stuff that were updated online...just plug it into the USB and update...sure its an extra "thing" sittin around or stuck to the glass, but i can take it with me or hide it unlike OEM units that get stolen....oh well..didnt mean to derail this thread...

back to AC's

Couldn't agree with you more BF... that is what I find anyway. It isn't about necessarily maintaining a certain temperature, but having either cold air or warm air blowing on you when you need it... nothing more frustrating than having hot air blow on you when it is warm or cold air blow on you when it is cold just because you turn the vehicle and the sun isn't shining on the sensor(s) anymore... I'd rather turn the dial to where I need it and be done with it. Same goes with the GPS... I want good sound out of my stereo, not endless warnings about operating the GPS, 1 min boot times, and having to "crack" it so I can use it while I'm driving. I've got my portable TomTom as well and couldn't be happier with it (other than taking the leap to download Mr. T's voice, but I'll get to that soon)... :D :D :D

I just think that $$$ could be used for things like new headers, new TRD Sway bar, and maybe even an exhaust... but hey, everyone has their own priorities, so I probably shouldn't rant here. :)

To the OP, it can be done and there is a list of all the parts that need to be purchased and used, but keep in mind that even at a decent price you're looking at well over $1000 and closer to $1500 for parts from eBay and/or junkyards. Do a search as there are several threads that comment on the subject and how to do it.

Really sorryy about the continued derail, but the thing with the Tom Tom is you can use ANYBODY's voice. Even your kids. You can get free software on the interweb, have that person record the key phrases, run em through the software and it makes a voice file you can dump onto your Tom Tom. Never tried it, but did look into it.

Oh, and back on track. Yeah, the guy on the Gen2 classifieds was selling his kit for $900 and that was supposed to be a good deal. Mind you, he was a little rude in some of his postings, but I'm gonna give him the benefit of the doubt. Take a look at his post and make up your own mind about if that is the direction you want to go and with that individual. I posted the link in an earlier post on this thread.

I still don't know if it was ever CONFIRMED that you definitely had that Venturi fitting to make it work...

Here's the thing about upgrading to the Auto system. For me, it's about the look; not the functionality. I think the dials, buttons, and readout looks great on the Auto system (especially the Platinum/Sequoia ones with the Black-on-Silver dials)... I don't care if the "Auto" function works, I just want the nicer looking panel.

If it can be done without the upgraded evaporator box w/ venturi fitting, then it can be done for less than $400-500 (considering you find the parts).

Eventually, I'll try it... but it's down my "MODS to do" list a ways...

I understand you meant "if it was ever CONFIRMED that you have to have the fitting to make it work?" Confirmed by who? If you mean yourself then you won't find out till you try it. The very few people that have done it already said so (i.e. klr_toy and I).

in short, it can be done without the upgraded evaporator box. But you need the venturi fitting (a must have item) that is pretty much unavailable separately.

Please share with the entire community how exactly would you do that mod for $400-500 (even without the fitting). Wait! You didn't mean that by buying used parts that (some, like ac computer) are pretty much unavailable on the used parts market. This is exactly the kind of thinking that makes you bash my thread for the price I'm asking simply because you think it "should", by your standards, be cheaper, when in reality it is impossible.

Thanks for posting the link. Just to clear some things, since you mentioned it: I posted my price and what the parts cost at the dealer (since most are unavailable on a used market anyways). Only the buyer on individual basis can determine whether it is a good deal or not, depending on his needs.

Thanks for the benefit of the doubt. I tried to stand up for myself so not sure where I was rude. All I did is posted the item for sale, honestly described it and looked for non-hostile environment. What I've received was bashing from those that know absolutely nothing about this mod yet still question what that mod requires or not, all simply because my asking price is not meeting their unrealistic expectations. While some of my reactions were a bit excessive (by my own standards) I feel no regret for what I said since my comments were all triggered by the repeated sarcastic comments from members not interested in my item, so in other words those, that should have never replied to my FS thread anyways.

Interesting that the members that were really interested in this mod pm'ed me to negotiate the deal. Somehow they didn't feel the urge to bash me for the price I'm asking because it is not what they are willing to pay. I guess those are the individuals that act like I would and I'm looking forward to do business with this kind of people.

Relax there Keyboard Tiger... I'm not bashing anything. There's nothing wrong with checking & double-checking to see if something will work. What I'm wondering is this: Like I've said, I'm not too concerned with the "Auto" functionality of the system... I'd just like the look. Perhaps if we just replaced the Thermistor & the Amp, maybe the system would work in manual mode, since it would seem that the venturi fitting bringing the air in is for sampling the cabin temp to adjust in the Auto mode. It's worth a shot...

As far as the price, at any given time you can find a Sequoia Auto panel on ebay, through LKQ online... for around $100 or less. Of course, this methodology is based on the assumption that the Sequoia panel will work on the Tundra. No one has provided a definitive answer as of yet, so if it WON'T work, then my numbers are incorrect, and you'll have to go out & find the Tundra specific panel.

The Thermistor new is $18.74, and the Auto A/C Amplifier new is $333.61. It was stated in the thread that you so graciously contributed to, that the rest of the parts (ie the "Ambient Temp Sensor" - $12.07, the "In-Car Temp Sensor" - $18.74, the "Light-Sensor" - $110.27, and the "Air-Hose" - $8.98) were not NEEDED to make this work.

So, if the "Venturi Fitting" is not needed, the cost would be:
- Control Panel = $100 (+/-, although I only paid $75 shipped, and assuming the Sequoia panel will work);
- Auto Amp = $333.61
- Thermistor = $18.74
TOTAL = $452.35

Again, I'd really like to try this, but it's moved down my "Mod-List" at the moment in favor of some other performance & aesthetic mods. If/When I try it, and it definitely doesn't work, I'll gladly announce that the Generous, Patient, All-Knowing and Humble PENER was right.... not a big deal. And if it does work, I'll post it with a nice DIY writeup so that others can use the info to make it work for them as well, if they so wish. I don't mind trying & failing to reach a definitive conclusion...

So PENER, can you explain exactly how to access the A/C Amplifier behind the glovebox? Do I remove both upper & lower boxes to get to it?

Funny but where did you get the balls to STILL keep asking me questions about the conversion after all we have been through?

... never mind, I pm you the info that should save you a lot of ground work and explains the inner workings of the digital ac system. And I did share all of that info on the forum many times already.

I agree that there is nothing wrong in checking and rechecking the info. I admire your passion. But a truly scientific way to approach already known "solution" is to quietly do your research on alternative methods and should you succeed finding one then, and only then, you should discredit work of others. Bashing my work at this point seems cocky on your part and very risky. You are making one assumption on top of another.

PENER just explained in detail the inner workings of the operational differences between the Manual & Auto controls... and he's absolutely correct: we need the Venturi fitting to make it work. If anyone would be generous enough to gain access to the hose & fitting that leads from the Thermistor to the evaporator box (I believe that's the one we need) and take some detailed pics and measurements, I'm sure we can make our own Venturi fitting, and get this MOD rolling for under $500.

Lots of members could benefit from this info, so hopefully somebody can oblige...

Again Greg, no bashing going on here... just a desire to make this work on a wide-spread & affordable level for the rest of the members on this forum. Hopefully we can work together & get it figured out.... :highfive:

Sorry if I made anyone mad. After Dessert Storm, I've had trouble typing with just my left hand (sometimes I get lazy and don't search like I should). Reaching is also the reason I want a Auto air condition. I have trouble reaching for the knob while driving. The point of doing other mods first was a very good point. I decided to do camera's to help me keep from messing up my truck trying to park it. Thank you all.
