I have a 04 T&C with a dysfunctional Air Conditioner System. I have a myraid of issues. I replaced the front expansion valve, pulled a vacuum then backfilled with freon. Then I paid attention to the fact that the front fans weren't running. I replaced the fans and the relay. It helped quite a bit by knocking the high presssure down by 100 psi. Now I have 40 psi on the low side and 200 psi on the high side. Still no cool air. And in fact the LP hose is warm, not cold. Any ideas?

 

how much freon did u put into the system?

 

I put in 3-4 12 oz cans, thereabout. I don't have a way to measure weight, and once I start charging and the low side pressure comes up, I cannot completely evacuate the cans. So all I can say is that I have about 43 psi low side, 250 psi high side, and 88 degrees ambient temperature. The unit does cool about 15 degrees of the air as measured by a thermometer in the outlet air duct.

All fans come on at the high side pressure of 230+ psi so that much is functioning well.

 

ok what was the original issue b4 u started replacing things?

 

the ac quit blowing cold air.

I believe if I were to have looked on the fan side first, that might have solved a lot. Since I found one fan out of commission and the other running at a low speed.

 

that would be an issue yes
