Wiring diagram for 1999 U320

December 11, 2024, 11:30:33 pm

Hey All Again
I do have another question. Does anyone have a wiring diagram for the AC clutch and the air conditioning condenser fan. I have heard around that time (1999)that the clutch on the AC pump and the electric condenser fan used the same circuit which is 20 amp. I may have a problem here and would like to find a wiring diagram.

Thanks again

James

I believe I have a pretty full set of drawings and I will check tomorrow evening.  Our builds are very close.

On my coach the AC clutch and the Condenser fan are run off two different relays.
