One usually does not repair these units. You will need access to a high pressure 12 ton, press to open unit for bearing replacement.. Cheaper to take unit to a electrical repair shop. If you are game, the usual problem is bearings, the diodes are fairly stable, but one can have it checked, for free, at the local auto store. If not, you will need a VOM meter, ohmeter checker, and check the each diodes, you will need to separate the diodes so you can get it into a testing arrangement. Diodes, or rectifiers, are one way valves, so when you attach the probes of VOM meter, set to the 100 ohm scale, and run a polarity test. One connection will show continuity, while a reverse polarity test should show, a open connection.

Is there a less expensive way to fix your 1994 Lincoln Town Car air suspension?

It is very expensive to totally redo the air stuff in your suspension system, but I think you can switch the air stuff out for a suspension system that does not need a computer and stuff. I have heard of a company call Strutmasters. You should check them out! I have a 1998 Cadillac Deville, and I had a big problem with my cars suspension. I found out that Cadillac dealers want anywhere from $3000 to $4500 to fix it! I could not sink that much into my car. So I called and they fixed my Deville for around $800! They had less expensive options, but this one was a complete fix for my entire suspension! I am very happy with the outcome!
