there are a large variety of things that can prevent cold air blowing, especially on the SVX - like the air mix door positioning.
you've probably posted before so please excuse my poor memory. Have you run the on-board diagnostics? Have you done the obvious checks (like the 1st question to computer users is have they checked to make sure the power plug is connected to the computer and to the wall), i.e., are you sure the compressor is turning and not just the belt, etc.? The best diagnostic is generally done with a gauge set, reading the high and low side pressures, at around 2k rpm. Without that I don't know if anyone could tell you if it was the compressor or some other component. |

Yeah, what Lee said!
Seriously, run the diagnostics for the HVAC system. When mine started blowing hot air I ran the diagnostics and found that the potentiometer on the baffle door was bad so the sytem wasn't letting the cold air circulate even though the a/c was cranking away - just got hot air from outside! This said, I still haven't gotten around to fixing it.... -Bill

I just did the 134 conversion on mine last night, it was working fine but then today started blowing hot
My first thought was a major leak, but after hooking up the gauge that came with the kit, the pressure was HIGH almost off the gauge. After liberating some of the 134 and getting the pressure back down it is blowing cold again.

thats it
I have that same issue the pressure was in the red but after letting some freon out its still hot and what baffle door are you talking about.I watched the a/c unit the belt is turning but it appears to be something simple that is keeping the a/c from blowing cold air.

Does your A/C compressor cycle on/off?

a/c issue
No it don't cycle on and off,its never cool inside the car for it to cycle.I will check my sensors and cleaned everything today before refilling it.

I don't really understand your symptoms, but tell me if this sounds familiar
My AC would work when it was cooler outside, but the hotter it got outside, the less often my AC would come on. Sometimes I'd get brief periods of cool air, but mostly it just wasn't working. While doing some other work on the car, I had the radiator out and I noticed that the front of it was covered in road debris - leaves, bugs, stones, etc. I sprayed it from the back and flushed all that debris off the radiator. Since then my AC has worked flawlessly.

I had just R134 installed almost 3 years ago and it's working fine.

My compressor is running my gauge with the recharge kit says my system is full but it continue to blow hot air.I will check what you told me also.

Are you sure the compressor is running? If you have the car running and switch the climate control from econ to auto, you can hear the compressor turn on?

I washed the bugs from the front of the car and the air still blows hot. I'm taking this sob to the dealership tomorrow.I'm hot and pissed its 97 outside and 110 inside with the windows down and moving.

ITS RUNNING
I'm standing here looking at the compressor running and the clutch is engaged that run the a/c.

run the diagnostics! if the variable potentiometer is shorted out you should still be able to get under the dash and jury-rig the baffle door open to let cold air flow...
