I get just over half a revolution easy, and it just stops!

The pulley/clutch spins free as it should.
I've never tried to turn an a/c compressor before. Should it just turn?
Is it seized?
Should I buy a new belt and see what happens, or did the seizing of the compressor cause the belt to depart?
I don't know if this will help, but I have had a similar problem before. In most cars today, that serpentine belt also serves the A/C compressor. My old car (1987) had a non-functioning compressor and it seized up and the car would no longer run. It is possible newer A/C belts are designed to break before seizing the engine. It took me about 2 hours of walking and waiting for a tow truck to realize that the compressor seized, so when I got back to the car and my waiting friends all he had to to was cut the belt off. Since the A/C already didn't work, the rest of the trip was uneventful. Today in most cars that belt also serves the fan, so if the A/C froze, a tow would have been the only answer. In my PHEV Mini Van the A/C was run electrically with its own electric motor. So, in the future, there will be no A/C belts at all. In my coach the compressor was 43 Feet behind the air handler. The system never worked from day one. That is 86 feet of refrigerant line. Trying to find a leak in that 86 feet wasn't worth my time since that tiny A/C unit didn't do much for the rest of the coach anyway. Almost, the entire 5 years I owned the Coach I simply ran the Generator and the A/C units on the roof.

In the 5 years I had the coach from new, I had problems with the 3 units on the roof as well as the automotive air conditioner. I have had a tiny tear drop camper for 5 years from when it was new. Both the A/C unit and refrigerator had to be replaced, both Dometic(A/C) and Norcold(frig.) said neither was installed to their specifications by the coach manufacturer nüCamp. There was no way to change the location of the refrigerator, but the A/C unit I had reinstalled to Dometic's Specs.

Can you possibly share with us the name and location of the extended service contract supplier? They ceertainly didn't make any money off of you.

Dash A/C Compressor

Yes, you should be able to turn the clutch be hand. You won't be turning fast enough to develop pressure, so that will not pose much of a problem. When the compressor eats itself, that's when the expense goes up. The cycle is Compressor, Condenser, Orifice Tube/Metering Valve, Receive/drier and Evaporator. The shrapnel from the compressor gets into the condenser and the Orifice Tube/Metering Valve. The Receive/drier has to be replaced when the system is opened. Unfortunately most condensers can't be flushed because they are parallel flow, so this must also be replaced. Parts alone are Compressor, Condenser, Orifice Tube/Metering Valve, Receive/drier. Flush the rest of the lines and the evaporator.

X2 what Gary said.
TMD described far more than I know about the coach air system in one small paragraph.

Holy Smokes!
I have about 120# of recovered and very well filtered R12, close to 200# of R22 same. When I was going to recycle it, the recycler was willing to give me top dollar for both ($19 / $30 resp.). I also have around 50# of reclaimed R134a. What is really sad is that I have about 500# total (separated) of burnout that nobody wants to touch. I can't give it away, but I can certainly pay to have it processed. I wont touch 410a/b, never got around to upgrading my equipment yet.



R290 & R600 I burn off in my weed torch. No problem there.


If anybody wants a really good deal on R718, let me know via PM. I have really cheap access to hundreds, if not thousands, of pounds of it.


In return, I am looking for R717. Hard to get a hold of, even through supply houses. Nobody wants to mess with it as it is associated with ... nefarious activities.

Does anyone know where the A/C charge port is located on a 2022 Cornerstone?

I have a 2022 cornerstone and the dash A/C seems to need a charge after sitting all winter. Does anyone know where the charge port is located?

Very top center of the fire wall up high. It will have a blue cap on it. You can follow the hose up from the condenser, behind the fan in front of the step box.
Here are some great photo compliments of Larry. https://www.irv2.com/forums/f278/dum...ml#post5749243

You'd think these dash air systems would hold up better than they do. My 66 Mustang I've owned for 47 years now has had one compressor fail in all that time so I switched to a Sanden Compressor and R134 20 years ago and not one issue since doing do.

Now our 18 Aspire dash air died 2 years ago. Took it to Cummins in Cincy. They replaced the high pressure fitting at the compressor. It worked long enough to get home (1 hour) before all the refrigerant was gone.

I just got it home again today from a local Truck shop with some skilled experienced techs. New compressor! They said the last repair had 3 O rings in the fitting where it was crimped on trying to get the leak stopped to no avail. So these guys changed everything out. It was blowing cold when I left the shop and I have about 4 weeks to test it weekly before hitting the road for a bit. I'm confident they got it done! No bill yet as the boss is out of town but I should know in a couple of days. Thank goodness for the extended service plan to ease the pain.

From all the failures after pump replacements I think the systems are not getting flushed out. It's why shops want to replace everything and flush the hoses. Very expensive for the customer.

I think you are right. When getting a new unit for my home my brother in law, who is a A/C tech told me to get the lines flushed out and exactly which product to use. They typically didn’t do this; I insisted and there have been no problems since the installation, while my neighbors with the same type of townhouse condos all has issues within a few years of their replacement. (I can’t remember the name of the stuff they used to flush the lines with.)

Also, I have a new “Park Model RV” which is stationary. It uses a standard A/C system. I can use a regular A/C company now. No RV or automotive service department only specializes in A/C units, so they are never as good as A/C specialists. I am so happy to no longer have an RV. My next RV will be a custom Van conversion; I have a friend that manages a company that can make a custom RV for me. I will design every inch of the new RV. (Boston truck and van )

I'm curious, what non industrial uses are there for R-717 ? I just retired from a large Anhydrous Ammonia Plant and am well aware of the EPA and OSHA regulations surrounding it. After servicing and breathing it for over 30 years, if I don't have to mess with it, I'm not going to.
