Hey guy's. I've searched around for this subject and haven't been able to come up with much anywhere. My car has the load leveling rear suspension from the factory. I'm trying to get it working again- as it should. Is there any online resources I could look at that's available? Service manual, system schematic?
I can pump it up under the hood with an air compressor/tire inflator, back end goes up like it should. System does hold pressure for awhile. One rear shock I found does have a small tear that leaks. I can hear it only when I'm under the car. Very slow leak. Is there anything I can seal it with that will hold?
As said above, the system will hold pressure, but if I turn the ignition on it lets it back out again at the pump under the hood. It lets it out to where the sensor in the back senses that the car is level. I have checked the system right after and it still has some pressure in it(unless I let it sit for a few hours, then it all leaks out the rear shock). My problem is that it then won't pump back up after the car has sat. It has never powered up the pump by itself.
I recently disconnected and pulled out the pump. I pulled it partially apart on the bench and checked it over. I re assembled it and tested it by connecting the pump motor directly to another 12v battery. It turns out that the pump works fine. Came to life with no struggle and is pushing plenty of air. I tested for power at the connector under the hood (that feeds the pump itself) and with weight in the trunk, ignition on it had NO Power going to it. Is my control box in the trunk fudged? Is the height sensor bad?(I wouldn't think so since it tells the system to let it out to a certain point) Something else? Is there a relay for the pump motor I could check? I don't know where to go now for more trouble shooting. If I can get the pump working as it should I will see about fixing that rear shock, or find out what good replacements I could get to take the place, but until I get this system running there's no point...
