I have just very basic knowledge of the A\C on vehicles. My question is this; What causes to high of pressure on the high side? I still need to get a set of manifold guages for both low and high sides so do not know the pressure reading of the high side. I do have a filler with the guage built in. When I hook that up to check the freon (R134A) it pulls to the bottom of the gauge (I forget the numerical reading). Would the system just be a little low, or have other problems?
When I run the A/C for more than a half hour, it makes the truck run rough, (spit sputter strain to go), temp gauge rises a little higher than normal, but stays to the left, like on the gauge say NORMAL, needle points around at the O and R. Would Evacuating the system and pumping it down over night then re fill do any good?
