      What is the GM part number for the O-ring?  Find out, and cross it to something in the aftermarket if the GM part is discontinued.

      The Genuine GM service manual set for your vehicle is your friend. First Guess:  If you can get in there from the HVAC blower-motor area with a vacuum, and perhaps compressed-air on a long, thin nozzle, you don't have to take the evaporator OUT.  Then the A/C system doesn't have to be discharged, desiccant pouch replaced, (new accumulator) system evacuated, and re-charged.  IF (big IF) the system is still leak-free, you aren't disturbing any of the seals. OTOH, it's a pain in the tuckus to REALLY clean an evaporator.  But it's probably even worse to replace one.  Good luck. If you do have to open the refrigerant system, be sure to replace the desiccant, and be sure to replace EVERY O-RING IN THE SYSTEM.  And have a careful look at the condenser for leaks and folded-over air fins.  Might be a good idea to just upgrade the condenser while the system is apart.  Remove and examine the orifice tube--any debris, and you need a compressor, too.  Flush every part you intend to re-use (except the compressor) and use the correct oil for the refrigerant you're using--in '92, that'd be R12 as OEM.  So again, "good luck".

      Hello if this has been posted already it would be greatly appreciate if someone can share a link to how to replace the ac evaporator in my 92 . It’s so packed full of junk it hardly blows any air and blew out the seal at the bottom so clearly I need to remove and clean it out. &nbsp

      I’m changing my reservoir on my 04 grand am. The o ring that is between the reservoir and the pump itself. Was bad. I cannot for the life of me figure out the size of the o ring. I’ve tried about 8 different ones and every one leaks . Any help would be much appreciated

      New carpet next to the old one for comparison. This is just a test piece as the cut pile option no longer has graphite available to match the old carpet. The original carpet had alot more padding under it too, the Vert seemed to have twice as much. Its just a basic carpet pad easily found anywhere they sell carpet.  This task is going to be alot like laying carpet on a spindle staircase with a shift lever and at least 20+ bolt and clip holes/slits that will need to line up perfectly or you`ll have lumps and wrinkles.
