So I have issues with my ac. I tackled the heater valve and the evap. temp sensors. Sorted them all out. Did not find any burnt traces on the ccm. Loaned an ac manifold gauge to diagnose the system and saw this... [img=http://s30.postimg.org/qj6rzv3tp/20140723_204315.jpg]

If you cant see the photo then I can describe it. Low side showing 115 psi and high side 145. Ambient temp at 80F. Does this describe a problem with the compressor?

Thanks

 

Low side pressure is WAY too high! Sounds like your system could be overcharged... Is your compressor clutch engaged?

 

Is this with the engine running AC on?

 

Yes this is with the engine an ac on.

 

Purchased this car 6 months ago. I never charged not sure about before though. Ac ran with no issues and car ran smoothly. I know compressor clutch engages because I get cold air, albeit only from the drivers side. Im sending in my ccm for repair on ebay. 60 something bucks for ther service. If that doesnt correct the issue then ill replace the compressor.

 

I'm wondering if it's overcharged.

 

I`ll entertain that question. I`ll take it to a buddy of mine to evacuate some of the refrigerant from the system and see if that solves anything. The previous owner could have just overcharged with a refill can. I have nothing to lose since I plan on to recharging the entire system at one point. I will update by tomorrow.

 

If you have no leaks at the compressor (back, front by clutch or on the bottom - middle) I would fully evacuate the system, pull vacuum and see if the system holds vacuum (if not you have a leak somewhere) and recharge by weight.

 

I need to change my A/C compressor on my S Type 3.0L 2000 model. Read your message from a few years ago and was interested in whether you are still happy with your four seasons compressor?
Thanks

 

Update. It was the air compressor. Also changed the drier (desiccant bag that goes into the passenger side tube of the condenser). All is well. Now I have a cracked radiator that i have to sort out. There's always something
