Hey, got a 2003 GM LSE with 212k miles! About 3 weeks ago i noticed the A/C would seem to fade out, then the fan wouldnt blow at all. I pulled the EATC resistor and re soldered the problematic pins on the board. The fan began to work like a charm!
Now its taking about 5 min on average for the AC to kick on.
With the car running and the pump off im seeing 90psi on the low side and 90psi on the high. So the system is static.
When the compressor kicks on im getting the low side slowly fluctuating from 35psi to 45psi to 35psi in that continual loop. The high side on the other hand is rapidly bouncing between 200 and approx. 215psi.
After a few minutes of running the low side appears to level out at 40psi, but the high side is still bouncing.
The car will cool, but dosent seem as good as it once was. Im sure with its age it needs a new evaporator, orifice tube, recharge, etc. However im not sure what the fluctuating high side means, just want to make sure i dont have a compressor problem first.
Thanks for any help!
