My car blows cold, I stuck a thermometer in the vent and after about 30 min. of constant driving it was able to make it down to about 35 degrees F. But once the cabin gets to that temperature then it stays cold. If I turn it on and let the car sits on idle it will never blow cold. It will get cool, but not cold. And on super hot days like 90F plus then it will take forever to reach cold cabin. Any ideas? Thanks

If you car has a sight glass, check for bubbles, feel the return line (suction) to the compressor. Should be cold all the way back. Pressures will be needed to properly diagnose the system..Hope this helps..

Yeah exactly 90F and my car is not performing how it should be, thats why I am concern. I took a readings and at the car idle the low side reads about 31psi. High is about 190-200psi. When I rev the motor, the high side goes up and the low side goes down. What does this mean?
It could be 90 degrees and humid like it gets here. When its like that its the worst.

Wow, Im glad i'm not in that situation. But can anyone explain to me what the HIGH and LOW side means. On gauge I should be looking at the most inner number PSI right? What does it mean for HIGH and LOW side. Thank you.
The big numbers around the outside of the gauge dial are psi on a gauge sold for the US market. Ignore the inner scales that are calibrated in temperature for various refrigerants.
I did all my test and now I think I have a weak compressor. I took out my gauge and measures the ambient temperature and got 65F. I put in the gauge and turn the car on. The high side should be at around 143. But my high side sits around 115-120. It cannot get any higher than that. And I know this is weird because I put more than enough freon in. But now that is my best guess and I am not 100% sure so I cam on here to ask is there a way to test the compressor to make sure it's still strong? Thanks.
