Jet Air Ride Problem(s)
1993 Winnebago Elante 33RQ Single Rear Axle w/Jet Air Ride Suspension
Hope this is in the right forum. Here's a little backstory. Came back from trip and very close to home blew out the passenger rear airbag. Did some price checking including calling Jet Ride on replacement bags thinking I was going to do the job myself. Got a very good quote on price to replace bags and labor from a RV shop in Oronoco, MN. Made the appointment, dropped off the MH and waited for a call... and waited... and waited. Called them several times and each time was told that they had never worked on a system like this and they had to figure out how to do it and were having problems getting airbags. This was a bit annoying because on making the appointment I was very forward about my MH, my airbags and system and even provided them the part number I got from Jet in Iowa.
Finally got the MH back 3 weeks after dropping it off. Drive the 40 or so miles home, park and find out that the rear has lost all air. Tried to air it up with my Harbor Freight 100 psi little compressor which has always worked before as the onboard compressor has never worked and I manually fill from the rear tank. No luck. It has always worked before but not this time. Figured maybe I need more pressure so I wheel out a larger compressor with a 120 psi rating and up she goes. Nice. Let it sit for 24 hours and still up. Great. Take it for a short drive through town and all of a sudden a pop, hiss and down she goes. Dang.
Back home and do the same drill. Out with the larger compressor but no matter what I try it will not come up. I can hear the switches opening when I work the manual rockers on the dash. I know air is going into the tank. I can't hear any obvious air leak or rushing or hissing of air. It just wont stand up. Figure I have two problems.
First... Why did I lose air in the first place? There must be a ride height control valve or pressure relief that is broke, not set right or let loose but I'll be danged if I can find it. Refering to the Winnebago manual and the Jet Air Ride "handout" that came with the MH doesn't really lead me anywhere.
Second... Why can't I at least build pressure and raise it?
I'm thinking these problems are related. Has anyone had this problem before or have some insight? Prior to this absolutely no issue with the rear air suspension. If I could hear a leak that would lead me at least somewhere but as I stated I can't.
Thanks for reading this and I'm hoping someone chimes in.
