I have several. My truck is the only one with ac and it's hard for my mom to get it. Cant really afford to fix it right now either. I need to look at the clutch on my old pump. I'm debating on buying a refurbished pump. Probably cheaper than a new clutch.
I brought my old pump in. Gap is about .020. I hooked a battery charger to it and it pulled the clutch in. Pulled the cap off and it had pressure/suction. I dont know why I pulled it now. Guess I will see if I have any old posts about it. The gap on my newer pump that is slipping looks much smaller.
Found my old posts. Some reason it said the gap was .035. Pump is sealed up but has been outside. From my old post I may be having the same problem. Sometimes a bad memory is good but most times that's not the case. I think this is above my head. AC did work great for atleast one summer.
