Hey everyone. I have a 2004 Freightliner (says Dodge on title but okay) 140" high top cargo.
I just bought it and got it running. But now I'm moving up to NY from TX at the end of July. And my A/C is insufficient. When I say insufficient, I mean non-existent.
Here's what I know:
Compressor works. Clutch engages/disengages with the A/C button.
Condenser fan works, and spins the right direction.
Pressures are good. 40 low side, 200-300 high side depending on the condenser fan.
The recirculate flap is broken. I'd have to remove the whole box to fix it, but I'd be willing to if I have to.
Fan speed only works on 1, 3, and 4. Speed 2 just gives me the same as speed 1.
Temperatures are around ambient across all vents.
Cabin air filter is new and installed properly.
Here's what I'm not sure of:
Interior temp sensor might work? Fan spins.
Temp control knob might work? I get heat when I turn it to full hot, but nothing cold when at full cold. I may take it apart again and spray electrical contact cleaner in the potentiometer.
And that's about all I can come up with.
Please help, I don't want to drive in 100+F temperatures with no A/C.
