So im just about at my wits end over this. But i have an AC that no one seems able to fix. I have replaced the condensor compressor, expansion valve, dryer, evaporator, wireing, blend valves, control, fuse box, CCU, filters, filter houseing, had the vents professionally cleaned, accumulator relays fuses and a few other things. Coolant is at 3 pounds per the book, lines are new everything works as it should.
Basically the whole system at this point. It will blow ice cold for about 5-30 minutes then turn muggy and hot and absolutely pour water off the evap and only works at all at max ac. Hell i even replaced the replacment control. 5 diffrent dealers 3 road side shops and a specialist cant figure it out. Hell i even have checked for valves, the dealer has checked for valves and by all accounts it should work fine. im at a loss at this point.
Anything at all that im missing? Id love some help because 4 months at over 100F in the cab with no AC is getting insane and i simply am out of stuff to replace.
