I have a 2001 Dodge Ram 1500 5.9 liter. My fuse keeps blowing. I unplugged Compressor and disconnected the low pressure switch. It still blows. I don't want to tear into the wiring harness. I was wondering about the relay or other places I should look before the wiring harness.

 

There is an a/c relay in the pdc under the hood. You could try replacing that, and see if it makes any difference. (just swap it with another similar relay for testing purposes.)

 

I am having a terrible time trying to get my 01 Durango a/c (dual system) to cool properly, in my opinion. My gauge reading on an 85 degree day are 26 suction and 175 on the discharge.
I replaced the expansion valve and accumulator\dryer, measured and installed the 2.22 lbs. of 134a refrigerant back into the system after evacuating of coarse, but can only get 60 degree vent air at the reading listed above at 2500 RPM.
Is this correct, or what else can I look for as the reason for not getting colder air in the cabin?

Thank You

Sounds like it is still low on refrigerant. Low side pressure should be higher than that at 85 degrees.
