I have a question for anyone or any service tech. No other tech reps at the dealerships will speak with me. I have a 2002 WRX and I'm having trouble with my A/C. There seems to be a clog somewhere because the compressor kicks on and stays on but no cold air comes out of the vents. i tried to find some sort of filter, but it seems these cars use an expansion valve. I don't know if this is the problem....or the condenser may be bad.....clogged line...I have drawn a blank. I don't even know how to get to the expansion valve. I bought a new compressor thinking that was the problem, but now the old one still wants to work....it had too much freon before (my fault) which caused it to lock up, but draining some made it work again ( you think the dealership will give me my money back for the new one?). Anyway, this thing is driving me crazy and any tech info would be GREATLY appreciated.
