I have 2001 Dodge caravan with 150000 miles on it it has a new ac compressor new expansion valve blows lightly cool about 48 degrees coming out of the vents and when the temps 90 and above you might as open the windows at about 85 it works ok number on the gauges low side is 28 to 33 the high side about 190 to 225 sure the right amount of 134 in the system.
Hi, please have a trusted A/C mechanic check your Drier/Filter if it's not clogged up. Also your evaporator and condenser if it's not dirty, clogged or leaking. As well as your condenser fan if it's still working fine. Lastly if all your a/c pipes are not leaking too. As well as the right freon levels.
Should have included the dyer in parts replace I bought a infrared temperature gun and sprayed the condenser out with garden hose but noticed on the condenser the temps are not a lot different from the top to the bottom how much of a temperature differences should there be from top to bottom of a condenser?
