A/C Not getting cold enough, duty cycles?
i know these a/c questions are getting beat to death but it is gettting warm out... here is my issue. my ac was only getting down to about 42 deg. F after it was running for about 15 minutes on recirc. so i vac it down for about 1.5 hours and weighed the proper charge back in. it is doing a little better now, about 40 deg. f. but it takes forever for it to get there and i have to run the fan full bore the whole time. btw, my pressures were between 35-40 on the low side and around 250 on the high side. the pressures seem ok. im just wondering if i dont have another issue? perhaps the txv or the accumulator? a few more things, the outside temp was mild yesterday, about 72 deg. F. the other thing that i noticed is that the cooling/condenser fan doesnt ramp up to full speed when the ac is put on max. i was under the impression that it should. i also can stop the fan with my hand on some occasions the fan does run fast so this is confusing as to what is going on. basically what im trying to accomplish here is get my ac colder so i dont have to run the fan full bore all the time. im just afraid that when it gets into the 90's here i am going to be sweating my nads off... sorry so long and any help/suggestions would be appreciated!
Did you have this vehicle last summer? If so, was it any better? Many ZJ owners report that the AC systems in them simply aren't up to snuff when pitted against the hottest climates, like here in the steamy jungles of South Florida. I think the evaporators are too small, and prone to clogging.. I've had mine for three summers now (this is the fourth), and it has never been able to cool the entire cabin/cargo area. Just too much space.

I noticed a big difference when I converted an older Camry to R134a. Wished I hadn't, but Freon is just too hard to come by anymore..
