Airmatic Issues, again. Dead pump?
More airmatic issues.
Noticed the car was getting more bouncy, and noticed my drag radials were starting to rub on bumps even though they were fine before. Was also getting the visit workshop with the cute little airmatic is busted picture.
Now, it seems like the passenger rear is the lowest of each corner. But, the issue is even when trying to raise the car up, the car does nothing. When I had a blown front strut/bag, the car would atleast try to go up, and you'd hear the pump working, etc.
I can't hear anything, and the car itself looks lower all the way around. My drag radials also poke pretty good, so I don't think thats allowing the car to drop all the way down if it was a bad rear bag.
But I just don't see it being a bag. I can't hear the pump working at all, and even the fronts wont go up at all.
I purchased a new relay, and a used pump that was in fine working condition (70k miles) and still nothing has changed.
I cannot raise the car up at all, and I can't hear the pump. Usually when I'd open my doors, Id hear a rush of air sometimes.
I checked the airmatic fuses, and they were fine.
Would a blown rear bag cause the car not to raise? I can't really drive the car anywhere, so is there a way I could test the pump without ripping it out of the car again?
Also, do the airmatic functions work while the car is in Battery Protection mode? I also had an issue with my battery dieing as well, and I pulled number 6 fuse last night to the audiogetway to rule that out, but even after having the car on for 30-40 minutes I never got all the functions back. Battery was pretty dead.
Any insight? lol

I don't think its the subframe bolts. I would hear/feel it. Is there 2 level sensors for the rear, or just 1? I figured there was 1 per side.
This happened randomly when I left my hotel and came out to the car when I noticed the level light. I'll check the level sensor and the fuse today.

Okay, so the fuse was blown. Now I can hear the pump working when I turn the key. It cycles, then soon after the visit workshop shows up again and the car still won't raise up or down. Not really sure what else to try at this point.

well, I have my old pump that I thought was bad out of the car. I suppose ill test it out of the car and see.
But is it wrong of me to think, even if I did have a bad bag somewhere, that if the pump was working correctly, that the other shocks would get air and the car would raise up?

I appreciate all the help.
Another thing. If for some reason something was messed up with the rear level sensor, would that keep the fronts from airing up or down? Im just trying to narrow down the possibilities of what might or might not be busted. I took a look and everything appeared to be fine. Subframe looked fine as well.

Figured id update. I'm not in a huge rush since I cant drive the car for another 2 months anyways, but I unhooked the line from the pump that goes directly to the valve body that sends the air into the struts. Since the larger/fatter line sends air into the filter, I undid the smaller one, and when trying to raise the car (thats when the other solienoid opens on the pump, letting air flow into and through the pump) the pressure coming from the pump was weak at best. Hardly blowing any air. I would guess the used pump I snagged has a bad seal. So I'll be replacing the seal.
I also built a connnector from some aligator clips, wire, and a perfect fitting spare plug body I had ordered. I made a circut that uses a car battery to run 12 volts through the pump to test it. I tested my older pump that I assumed died and blew my fuse, since when plugged it in the pump does not kick on.
I'll make a video on what I bought/used, and give some examples. I know this system is a pain to trouble shoot, so hopefully this helps in the future.
Edit: Also, when I tried raising the car, the pump 100% was running as it should.

Thanks for the update. I'm watching all of these Airmatic issues closely because my Visit Workshop light also comes on sometimes. The ride level is fine, but if I raise the car the driver left does not go up. Hope I don't wake up to a slammed car one morning.

If the left side of the car doesn't go up, you probably have a bad strut or a leak on that side. There's only 1 level sensor that controls both rear struts, while the front has its own individual sensor on each strut.

Your right, but the ride height seems fine. I'm trying to decide between the start of a bunch of costly repairs as the Airmatic system fails, or just bite the bullet right now and go to Strutmasters or some other non-air system.
