I have a 89 GV with 3208 Cat. Looking for the location of the A/C relay. Also does it have a separate relay for the condenser fan and where it might be?
If you have a B-2126 Automotive Wiring schematic for your coach, you can find the (approximate) location there.
If not, do you know where the battery isolator is located? Look around in that area for the two relays.
Probably behind the left will make some difference on condenser fan location. rear wheel mounted on the frame rail. Do you have a unihome or the Oshkosh chassis? That
The clutch relay may be grounded through the low and high pressure switches. My clutch hot wire runs over the engine, and down to the compressor. I think the relay is near the cruise panel.
I removed all of this system due to multiple failure points. 60 Ft of old hoses, compressor, fan switches. I replaced the compressor with another Alternator.
It's like a full time hobby keeping the thing working. Now I run the gen set and overheads.
I hope to add a mini split to take up the slack..
My AC Relay is by left rear tire and mounted on a plate just below isolator. 1992 U280.
