Hello everyone. This is my first post and I need some help trying to determine the course of action to fix the a/c on a 99 Toyota Solara V-6. The system blows warm air, 70* with a full charge. The ambient temp here is 68*.
The compressor comes on and my guage readings are 15-20" of vacuum on the low side and 100psi on the high side at 1500 rpm's. I'm not sure how to interpret these readings and would like to know if there is a specific failure or could there be more than one possible cause? I do some a/c work, but sometimes I get a bit concerned that I may mis diagnose a problem like this. I also noticed that the guage readings do not equalize after turning the car off and letting it sit for 15 minutes.
Any input would be greatly appreciated. Thank You
