E36General discussion and technical help for (E36) 1992-1999 3 series cars. 318, 323, 325, 328.
My A/C has been blowing hot air ever since I had the car. I assumed it was low on R134a. I bought the recharge kit and went through the process of refilling. Turns out the freon level is already perfect. What else is the problem? I can hear the A/C engage and the RPM's dip slightly So I know it activates.. Do I need a new compressor? or what? Thanks for the help..
Yea the level was good according to the gauge on the can. And since the system was holding good pressure it can't be a leak. When I put the A/C on the rpms dip and the aux fan kicks on so does that mean the compressor is working?
so u have the AC on when u checked the gauge on the can?
i did this to mine last week my steps to a full recharged system was:
1. attach r-134a to low connection ( can should read overfilled until u turn on AC)
2. turn on car and have the Ac engaged (can should read zero or empty now)
3. have some one inside give a bit of throttle as you untighten the screw so the freon will come out. Person inside should say that they feel the cooler air. and when the can is empty or at the safe level on the gauge youre done.
I basically did the same procedure. The only differemce was I did not have anyone rev the car. When I first attached the can with the car started and A/C on the gauge read that it was at a good level. I tried to spray more freon in anyway but it seemed as if it wouldnt allow more freon to go in..
