At least that is what i feel and everyone else in the family as well. However, i hooked up a gauge to the low pressure side and the pressure reading was dead perfect based on the ambiant air temperature.

Assuming that is true, what else could cause the system to cool, but not as well as before? In my humble opinion, i would say cooling is at least 25%-33% worse than before.

fyi, the ac system has never been serviced.

Love the air box modification. Is that an oil filter? Got anymore pics of that?

low ref. charge, dirty condensor, dirty evaporator. I'd get it recharged and go from there.
yes i am talking about the a/c. the refrigerant level is fine. don't know how to check dirty condensor or dirty evaporator. can anyone explain how to check this?

The condensor is mounted in front of the radiator. Check it for bent fins, squashed bugs, etc. The TSB mentioned above is probably the best place to start.

Check out the TSB on the temperature adjustment... my 02 had the same issue... quick fix, and super cold AC once again!
Where can this be found? I did a search, but must still be overlooking it......

Thanks.

I believe they are talking about the cable stop adjustment. The temp control knob is attached to a cable that goes to the water blend valve on the engine compartment side of the firewall. The cable may not be adjusted properly and may be letting hot water through the blend valve even when the temp knob is turned all the way to the cold side. You can adjust the cable to shut off the hot water flow completely when the temp control knob is all the way to the cold setting.

Would you guys happen to know the exact details on this or perhaps a copy of this TSB??? I need to figure out whats up with my AC. If its not on full blast the cabin doesnt stay cool.
