1990 DeVille

Maybe the radiator fan, or the self leveling motor which may be enough to last for the 5 minute "on" time. Pop the hood and look and listen for either.

Thanx folks, , , ,

That's what it appears to be, , , , The leveling motor.

I appreciate the answers, , , , , ,

It's been about fifteen years since I've owned a Caddy, and none I've ever had, have had these fancy "automatic" features. I wonder if these things runb down the battery? I live in the California High Desert where temps are in the 120's and up everyday in the Summer, and I don't have a garage, so this puppy really gets hot inside, , , ,

Thanx Again

====================================================

The crusie control on my 1990 Sedan DeVille is inop. The light comse on, and the display reads "engaged", but it does not work. I think it's a vacuum leak, but does anyone here have any hints???

Thanx

======================================================

I had a vacuum bellows go bad on me which causes the throttle control to be ineffective. Figure around $100 for a replacement.

Cadillac has a delayed accessory power that stays on for five minutes after turning the ignition key off. Your leveling motor will be without power after the five minute time period.
