Well the ac took a dump on the 2005 3.5l Pacifica and looked like it was the compressor was at fault for multiple reasons. I replaced the compressor with a reman one, expantion valve, dryer, and flushed the system(not in that order). Well the Pacifica was in a wreck before my fiancé bought it and did not come with any tag to tell how much freon to add (tried to buy replacement but discontinued from Chrysler). Found some people online and came up with 24 oz as an average and figured I would add 24 oz and then just go by my gauges. Well put my oil into compressor, hooked the lines up, pulled vacuum, let it sit, and I everything passed so I went ahead and started to add charge. Well I added 24oz and my low side is about 37-40psi with car running at idle (hot 82 deg day with high dew point) but my high side only went to 100psi. I checked my thermometer in the center dash (fan all the way up, on vent, max ac) and its cold at 43 deg. Seeing if this seemed like a normal thing for PAC users. I was used to low side 30-40 about and 200-250 about on high side. Lemme know if that the high side number seems a bit different than normal.

 

high side only 100 is an issue make sure the high side port is secure on the port first.

U wont be able to get the temp reading u have out of the vents if u only had 100 on the high side.

 

Yeah I think your rigHt. I checked again and with it being about same temp/dew point outside today, fans on max ac, my thermometer was reading 40 on low and 100 on high again. I think I will try to borrow a friends gauge and check it out. Btw do you know if I should clean these gauge out once in awhile with anything in particular so freon, uv dye, etc doesn't clog it up at all? I guess you could say gauge manifold maintenance
