air suspencion question

[porrsher]

Fellas,
Looking at the air suspension issue on a 96 TC my sister in law owns, from what she tells me the rear end will go to the ground which tells me that there is an air leak in the system, however she also tells me that what she has been doing is letting the car level after a couple of on-off engine cycles in the morning then shutting off the suspension with the switch in the trunk and the rear end is fine for days when she does this... which throws my air leak idea out the window. If the suspension is left "on" the rear falls to the ground... Need help with this one please.

That's interesting..
Sounds like a dump valve is sticking intermitantly. The diagnostic procedures are rather lengthy.

You can get some free advice from places like:
Strutmasters
Arnott Industries

Or if you want to run the numbers by the book, the Ford book, you can download a free official Ford Service manual at wwwfordcds.com

He takes donations if you're a happy downloader

Start there with diagnosing the problem. It isn't that difficult. Could be a bad Height Sensor as opposed to a bad vent solenoid.
