2009 GX with front AC suddenly blowing warm/hot. Rear AC works well (nice and cool). It seems like this would not be a compressor.coolant issue as it is really one combined system.

Any Ideas? I have searched quite a bit and cannot find anything.

Thanks in advance for your help!

Could be an issue with your solenoid heat air doors no working correctly

 

Check your refrigerant level. Especially if you never have had it refilled. It's not uncommon for first one side of the front, then both sides of the front, to start blowing warm air when it gets low.

Go to a shop that specializes in auto A/C, or your dealer. Don't use a refill-can from Pep-Boys, etc. as you won't be able to get the correct amount in the system.
