379 pete a/c problems

C/k actuator @ right side remove panel where a/c filter is and remove actator and work it manual c if it gets cold then

 

ill try that tomorrow, is there only one actuator, i see two black boxes once under there... sorry for the rookie questions, not a lot of experience with big trucks, just learning as i go.. thanks for the input!

 

I had an odd problem with my A/C a few years back. Had an A/C shop measure the pressure in the lines and it was too high. So they drained the system and refilled it with the proper amount. A few weeks later, the same thing happened AGAIN. Almost had to wonder if the refrigerant was somehow spontaneously generating more of itself!

 

I have a 99 pete 379... My issue is that the bunk fan won't kick on.. I replaced the motor and nothing.. I have power at the connection, but once I plug it together the ground wire gets power...? Any ideas? Not to fun jumping into a cold bed....

 

Sounds like a short-circuit somewhere.

 

When it was working, the fan seemed to only work on low... Someone told me there is a resistor for the speed switch... I just dont know where it is.. Could that be my issue?

 

What kind of material did you use to cover the hoses?
