I've been searching for awhile just reading up on everybody's problems trying to pinpoint the symptoms the LS is having.
I just recently had the car into a Lincoln dealership for a full bench test on all the coils and replacement etc... The car runs great and I'm back up to 25mpg avg. However today I went to turn on my a/c and its not cold! :shifty: Now I swear to the big guy that I had cold a/c before I took it into the dealership. I've contacted them and my service guy will be talking to the mechanic tomorrow morning and getting back to me. I'm thinking they may have left something unplugged or somehow air got into the lines.
I've somewhat ruled out the DCCV because in prior posts if 90* temp control created hotter air than any other temp the DCCV is functioning properly. Now I've done ALOT of reading so if I've mixed this up please correct me.
I've read that even with a prolonged misfire the PCM will shut off the a/c. How is it turned back on if this happens? Naturally by the PCM or maybe a reset process. (I've disconnected the battery and drained residual electricity in the system to no avail)
This is all I've found as far as a belt diagram.
Now from the looks of it I'm assuming the lowest pulley on the right side is the A/C unit. Heres a picture of mine (assuming this is the A/C)
Now from this angle its hard to tell but it was running when I took the picture with the A/C on. IF what I read is correct shouldn't the inner part of this pulley (little nut looking deal) be spinning when the A/C is turned on? Basically the clutch in there is not connecting to even turn the system on? Am I on the right path?
I'm going to have a HVAC specialist come and pressure test my system and add refrigerant if necessary. I'm hoping I just need refrigerant as thats the cheapest option.
Any ideas? Sorry for the long ass post I just want to be thorough.
