Was blowing Really Cold air i stopped to pick up wife and left the car running, got back in car and started driving and it stopped blowing cold air now it was just blowing Air. i bought a can of AC recharge but that did not work as it still blowing air
TO MANY REASONS FOR IT TO QUITE WORKING IT WOULD BE BEST TO LET SOMEONE LOOK AT IT
SOURCE: A/C will suddenly send out heat. Fiddling with knobs seems to help. What's wrong?
You have a broken wire connection between the temperature control knob and the circuit board behind the center dash console. Vibration causes the failure and once the control knob gets loose the solder connection fails.
For someone that knows how to remove the dash unit and can re-solder a couple of new wires this fix should take no more than 1 hour. Make sure that you apply loctite to the heat control knob spindle nut when you re-assemble it.
The dealer quoted me 750 dollars to fix this issue and I found out that it's a common failure for this year. I fixed mine virtually for free but it took some tools and about an hour of my time.
SOURCE: no cold air from the ac in my 1989 toyota camry
Are you sure that is the problem?? Other things can cause this. Have the pressures checked first to see if the charge has leaked out, then you must find the leak. Also you have R12 in this system, R12 is no longer produced so you must covert the system to the newer R134 refrigerant, this takes a special kit being installed. So I guess the answer here is not you can't do this at home. The whole job will run about $1000.00

They said a compressor to start but my van had a valve behind the dash that take up to 9hr
