View Full Version : Question 2011 Sequoia AC can't take the heat?

So yesterday it was 95 degrees and it took 25-30 min to be relatively comfortable inside the car. Not cold; just comfortable. Is this what expect? Later at night when temperatures where down it seemed to kick in again. I've never had this problem with another car, so I'm guessing it's a real problem?

I also noticed a weird noise coming from the wheel direction or nearby like a CD booting every 15-30 seconds or compressed air. The noise is gone if I turn off the AC.

Any ideas? I'm going to take it to the dealer but last time I had a similar problem they told me it was by design....

Thanks!

I would assume you have automatic controls for your HVAC system right? I have experienced every once in a while that the system was set
on a certain temp and was working but somehow the A/C button had been pushed turning the A/C off while everything else was still working
to cool the car. I don't know if I pushed the button inadvertently or if it turned off on its own for some reason but after turning it back on
things chilled right down. I have had no other issues other than that, just make sure the A/C light is on while it's running. Good luck!

I have had similar intermittent problems on wife's '09 Camry with the super-duper auto A/C. I've learned that if I shut it off manually (by pushing the off button) before turning off the engine, then AFTER starting the car again then turning it back on to AUTO it seems to work fine.

It is always >100 here and my sequoia works great. 2011 Plat.

make sure when you have the A/C on you have the "recirculating air" selected vs. the "fresh air". If you have fresh air selected it will just pull air from the outside which in your case was 95+ degrees. I forget to select recirculating air all the time in my sequoia and as soon as I switch it over it's ice cold in seconds.

Yes, AC light was on. I think I tried the recirculating air button but I'm not sure now. 100s here are pretty rare and now we're back to 70-80s...

The noise still bothers me though.

When I bought the car I thought the AC wasn't good enough and took it to two dealers. They said it was ok. I'm kind of weary of trying it again now especially because high temperatures here are rare as I said (I would have to be lucky and send the car to the dealer in one of those days if it happens again).

2011 Plat here in Louisiana it's quite hot. Ours will freeze you out quite quickly.

Sometimes you have to cool the hot interior surfaces before it becomes comfortable feeling. Recirculate, top dash vents, and check that they are all open..

I regularly travel through upper 90s and low 100s (AL and GA) and have no problems with it staying cold....not cool, cold.

Oddly enough, I hate how the Sequoia always defaults to recirculated air. Where I live, fresh air is the better setting 99% of the time. That said, I spent the last 4 days in Palm Desert where it was 110+ and the AC worked like a champ, recirculated all the way.

I have a 2004 Sequoia and had a similar problem with the AC not cooling in the heat. I spend a lot of time in Lake Havasu City, Arizona during the summer when it gets really hot. I checked several things and found no problems, even took it to a Toyota Dealership in Havasu and everything checked OK. When I returned home I talked with the Toyota Dealership that regularly serviced my vehicle. I had them charge the AC and it did not make much difference. However I did take a look at the sight glass and noticed air bubbles in the refrigerant. I had the dealership redo the charge and to pay attention to the air bubbles and things have been much better since the air out of the system. I hope this works for you. Sam

Air bubbles can definitely decrease performance of the cooling system. Also if the interior is very hot, it will take a while for those surfaces to cool down, especially with all the plastic in our cars.

We have a black all leather 2010, and on hot days it can get downright deadly with heat build up in the interior. What I did to help slow this process was to drop the headliner and install a product called Heat wave pro from Second skin audio. This is a double reflective insulator. I glued this directly to the metal underside of the top. In addition, if you have a sunroof, I find there is a ton of heat that drops directly on your head because the cheap flimsy cardboard tray they have in there. So, again, I cut a piece of this insulator and shoved it up in there. It's easy to remove if I want to open the sunroof. Our car is easily 30-40 degrees cooler at max temperatures and it also takes it hours to heat up to max. Whereas before it would easily get roasting in 20-30 minutes.

Another area I notice a lot of heat coming from is the dash. Even when the car is cool, this area continues to be exposed to the sun and it doesn't cool very fast. So when you get a current of air across the dash, you'll actually feel an increase in air temperature. For this we have a very good sunshade when we park the car. Another way to cool this faster is to put the front defroster on, so you're pushing cold air over the dash. This seems to take longer to cool the car, but it will cool down all that surface area in front of your face.

If you could put a thermometer in the vent and measure the temperature of the AC air. Also, measuring the interior air temp before you start trying to cool the vehicle down would be good. Post what measurements you collect... :D

Depending on how much effort yer willing to keeping yer Sequoia cool, you could try something like the Cool Cap. ;)

Too bad they seem to be always out of stock. :(
