What i have is info on upgrading the compressor to a heavier duty, Sanden model U4664and it uses 15-pag oil you will also need to change the thermal Expension Valve, its a Parker 134-112 or Murry 38872, or Red Dot 71R-8100. Dryer replacement is a Red Dot 74R0906. I think if the compressor is lockec up the system needs to be flushed before installing anything.
One warning when charging the dash air on a side radiator coach put a shop fan on the condensor if not you will get hi temp and high readings on both low and hi pressures.

Reference your hi-low beam switch. On or 1997 Windsor it was an older style foot switch on the upper left side of the floor near the steering column. I'm pretty sure these are standard parts borrowed from the automotive industry.

Hi George! Welcome to IRV2! We're sure glad you joined the gang!

Can't help with the question but just wanted to say hello! Keep her between the ditches!

Good luck, happy trails, and God bless!

On my 98 Dynasty the compressor is a Seltec 0630 7404. I just typed in the number
in google and lot's of options. Good luck

George, did the belt burn off and the belt pulley is locked? You already may know that your compressor is toast and if so disregard any comments by me.

I have see where the pulley bearing has locked up, but the compressor is still good. If the center hub still turns, more than like it is just a pulley bearing on the compressor that can be replaced independently of the compressor.

If the belt is still good and compressor turns when running without the A/C on, and then squeals when you engage the A/C, then you are correct that it needs a compressor.

The only reason I mention the above is I have seen many folk replace compressor instead of just the pulley bearing.

George the condensor at NAPA is less than $30 , i have never heard of cleaning one as they are so cheap.

If the compressor seized it is very likely the the dryer has packed up and spit desiccant Beads through the system.
If you can, have a look at the compressor to confirm if this is the case and impress on the shop the urgency of cleaning the complete system.
The shop that replaced mine ended up doing it twice because they didn't do a good job of cleaning the first time.

There should be a tag on the AC Plenum that specifies how much product it takes to fill the system. Likely around 3 Lbs.

How do you guys know the part replacement numbers for your expansion valves and dryers?
I plan on installing a new Sanden compressor, expansion valve and dryer before next summer as mine leaks down every few months.

[walt2137]

Vito find someone with a sniffer to check at the compressor seal and all fittings for a leak, it dont sound like you need to change everything to me.

Vito.a, I removed them and took the parts to my A/C supplier.

2007 Monaco Signature Noble III
Dash A/C
Compressor Sanden U4475
Receiver Dryer UAC RD 6166C
Expansion Valve UAC EX 9441C
A/C Belt Cummins 3682687 Gates K060630

In my case the 90° fittings at the compressor had to be re-used as I couldn't find one the right length for clearance. The supplier welded a new end on them, a common practice.

The Sanden model U4664 is a upgrade on the compressor to give a little better cooling.
