This question is a little off topic, but I figured you guys could help me
out. I'm needing to know what models and years of Cadillac cars had the air
suspension, so I know what ones to ask about at junk yards. I'm wanting to
rob the air compressor unit to put in my 1 ton Ram for an air supply. :-)
From what I've read, all of these compressors were driven by a 12V motor.
Can anyone help?
I bought the three Cadillacs new, the '84, bought in '85 and turned it in on
the '93 and that one I turned it in on the '01. Never had a failure with
any of them. But one thing to remember is that don't run continually. Upon
starting the car they may run for 20 seconds and will run if you add weight
in the back seat or trunk. All I can say is try one and see what kind of
service life it provides.
Cadillac used these electric compressors as far back as 1979, it was on my
Eldorado. It's possible they go back even further, but in the early 70's
Caddie used a vacuum powered compressor with a storage tank. Full air
suspension (as opposed to airlift shocks of the 70's and newer) was an air
bag device at each wheel with an engine driven compressor. These systems
were complicated and troublesome, and were only used from 1958-1960 after
being introduced on the Eldorado Brougham in 1957.
