jassrnj,
Based upon your description, I think you mean the chassis air too.
First of all, can you tell us what chassis your motorhome is on?
Second of all, are you home or travelling on the road?
Next, does turning off the A/C with the dash control stop the squealing? If so, then disconnect the clutch wire to the A/C compressor, you'll shut off the clutch and it will freewheel keeping the A/C compressor disengaged.
If the squealing stops, then keep the wire disconnected, the A/C compressor can no longer be engaged, and you are good to go for as long as you want. You won't have chassis air, but run your generator and fire up the roof top unit. Not perfect, but it should work to keep you mostly comfortable in the rig if you have the vents pointing up front.
If the squealing doesn't stop, that most likely means your A/C clutch is failing and that is going to require more immediate attention. I would NOT drive too far if this is the case.
If, by some chance, your rig is on a Workhorse chassis, I know there is a work-around where you can bypass the A/C compressor by using a smaller serpentine belt. I had to do that on ours when my clutch burned up about 5 miles from a campground we were heading to. I was able to bypass it and still use the rig until I got the situation fixed properly. If you're handy with tools and do your own work, it's not too bad of a job, even at a campground. If you need to bring it to someone, show them the bypass "option", if you need to travel and want a quick, cheap fix.
If it's the clutch, the clutch CAN be replaced by itself, if you're lucky, and you don't have to change the compressor. In my case, however, trying to remove the old clutch damaged the front A/C compressor seal, so I ended up changing out the compressor. THAT is not a normal do-it-yourselfer type job UNLESS you have the proper tools. It's not difficult, but you do need access to A/C tools (gauge set & vacuum pump) and R-134 refrigerant.
Good Luck,
~Rick
ON EDIT: Ok, I believe from reading some of your recent posts you have a Workhorse chassis. Read post #13 on
this thread for some details on how to bypass the A/C compressor, if that's what you decide to do. I also made a post on these forums a while back about the
belt and pulley numbers needed.
Click Here.And this thread will show the proper belt-routing with either the A/C compressor or without the A/C compressor:
