1991 Cadillac DeVille Problems

Heating & Air Conditioning -- Verified

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Brakes -- Verified

The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

Miscellaneous -- Verified

The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.

Suspension & Steering -- Verified

The electronic level ride system may not work properly; this may result in the rear of the vehicle riding too high or too low. Our technicians tell us that a height sensor or exhaust valve failure are common issues with this system. Proper diagnoses will be necessary to confirm the exact fault.

Electrical & Lights -- Verified

Problems with the anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The the key and ignition lock cylinder must be replaced to correct this condition.

Have a '91 Sedan DeVille that I bought in 2009 from orig owner. Had 74K on it. Wanted a comfortable car for long trips. Beautiful pearl white w/ navy leather. Was kept covered in a garage... No dents, chips, scratches----looks like new. Replaced the a/c compressor---bearings wore out, replaced the brake master cyl & booster, did a tune-up---still had orig wires & plugs on it. Love the ride, love the classic look, love the power. Had to take it out of the garage last year in the snow when my truck wouldn't start---the caddy was like a tank in the snow.... It didn't have the rear fender shirts---I'm looking for a set to install. Great car---love it!


Bought this car 4 years ago for commuting and its the best commuter car I've ever had. I travel 160 miles a day with it to and from work, gets in low 20's for mpg at around 70mph. Headliner needs replacing, typical GM issue and I've replaced a couple sensors and a muffler, not bad for a car nearing 200,000 miles
