SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

SOURCE: Low rear suspension on my 1999 Cadillac DeVille

Do you hear your compressor running? It may be that it is getting tired and ready to burn out on you. I replaced the compressor twice on my Deville before I found that there were so many holes and nicks in the air bags and it was going to cost me almost $1500 to fix the whole system. I went online and found Strutmasters. I got a non air conversion kit for my car and love it. Saved me money and headache.

This is most likely caused by an erratic signal to the Air Ride Computer from one of the suspesion height sensors. You will have to scan your Suspension Control Moduleto find out which one.

Air ride on my 99 cad. devill when people in back seat will bottom out rides to low


If you have Air shocks in the back they are worn out

Your going to get that low ride when people sit in the
back even with new rear shocks & a small adjustment to
the level control to raise the rear

You need to air your tires to the max on tire sidewall

The rear of the car sets higher than the front, suspension is stiff in the back to. Is there a suspension control system that is not working


There's a level sensor in the back of most cars that have air ride suspension such as Cadillac Devilles.

If there is plenty of pressure, it's probably not a leaky air shock aborber nor is it a bad air pump under the hood.

Service ride control


this waring means that the ride control has been unable to maintain the correct ride height, this is caused in almoast all cases by leaking suspension air springs, the last on average about 100,000 miles

Turn off air suspension on a 95 cadillac deville


On the Cadillac Devilles you may need a relay to turn that suspenison off. If you are having trouble with the air ride all together you may want to check out Strutmasters.com. They offer non air conversion kits for your vehicle at a lower cost than it would be to fix that air ride. Save yourself time, headache and money and check them out.

1999 Eldorado rear air suspension inflated to max


Converting from the air ride suspension to the passive coil spring suspension will eliminate this problem. To fix your air system you will have to purchase the parts directly from the dealer which means the prices will be severely inflated. Check out Strutmasters website at: http://www.strutmasters.com/Cadillac-Eldorado-Air-Suspension-Rear-Conversion-R-p/-cad-r5ns-el.htm My Uncle converted his Cadillac Deville two years and has only had positive things to say about the effects! I hope this advice was of some help.
