2005 Dodge 3500 AC issue
Posted: Fri Aug 17, 2018 8:50 pm
Bought a truck that AC was not working, was told I just needed to install the serpentine belt to hook up compressor and it would be good to go. Surprise surprise, that is not the case. Been chasing the issue for a few days and hoping you guys can help.
When I turn on my AC it runs right for about 30-45 seconds with gauges in the right ranges, blows cool air. Then you can watch the High Pressure gauge climb up to 300+ PSI. At this point the compressor kicks off and the Low Pressure gauge pegs out. Turn off AC for 2-3 minutes and then I can turn it on to start cycle over with a short period of cool air coming from vents.
Originally thought there was a blockage in the liquid orifice tube but I swapped that out today and same issue.
I have vacuumed system multiple times and recharged with correct amount of coolant and there is where I am at now.
My next thought is to replace the condenser, but before i throw more money at this I am hoping someone can give me some guidance, I am a IT guy, just know enough to be dangerous with cars.
Thanks in advance!
