Not knowing what exactly is the problem, hard to give any advice to a solution. I would first start with the relay switch on the pump/motor to make sure that is not the problem. Common failure point and fairly simple fix. If no joy there, then the electric end on the pump would be next. The pump/motor runs such a short period of time, that is an unlikely failure point. Not to say that it does not fail, but I would be sure to rule out the other components before throwing money at it. Ask the tech specific questions concerning the components, making sure he has checked them before committing to a new pump. Hope this helps.

I built some 2x10 wood ramps to get the coach up in the air to do under carriage maintenance. Start with a longer piece for the bottom, then the next one a little shorter, and so on. I just screw them together. I have some that are stacked with 4, 2x10’s. Gives you about 7 inches of clearance. Ideally, once coach is up on ramps, some jack stands placed underneath as backup is a good idea. Hope this helps.

Yes it would. Had the exact same situation as stated in original post, replaced air governor, worked like a charm.

The air governor is probably your problem. They are not that expensive. Here is what you need, Bendix Or275491 - D-2 Air Brake Compressor Governor Hope this helps.

Try this, they are not an exact fit, have been slightly modified. Spoilerlights.com. Third Brake Light Alternative | Type: SL-84013

Circuit Board in the Front Run Bay. Front Run Bay is located outside, under driver position. Good luck.

Yep, that Big Boy will get you if you are not on top of it!

There is also a relay switch mounted on the pump motor itself. It will work intermittently then quit all together. It will have a band clamp going around the motor. These are used on dump trailers if you need to source one. Hope this helps.

If they are flapping, I usually retract the slides until the wind dies down. It’s kind of a pain, as coach should be at full ride height before retracting, but better than replacing toppers. Hope this helps, good luck!

Is the bedroom location the only one that does not work? If all switch locations don’t work, then check the plug on the generator itself. I have inadvertently disconnected mine running the generator slide in and out, by hooking the plug on the framing as it was going by. Hope this helps, good luck.

My 07’ Marquis will retract the slides with engine running. This allows me to get to full ride height, then retract the slides without shutting down engine.

Can you get to it from the bottom? A heavy dowel or 2x4 pushing upward?

The switch has a button on it to release the knob. Wiggle the knob as you press the button and it should pop out. Hope this helps, good luck!

Looks like a Flare-It fitting, https://www.acehardware.com/departments/plumbing/pipe-fittings/pex-fittings/4165684?store=14420&gad_source=1&gbraid=0AAAAADtqLJHS2w7-aY7PR4j7w5VgXrqk-&gclid=CjwKCAiArLyuBhA7EiwA-qo80FVuV6KQnJFZOeFTQqzohgHzLZWJWOpC5l4b_1biML7Yn_Owz95sMBoCkoEQAvD_BwE&gclsrc=aw.ds. As Jim said, any big box store will have it. Hope this helps, good luck.

Wow, thanks Frank. Never knew that was there! My eyes are not what they used to be. Will give it a try and see what happens!
