Sometimes the battery has to be disconnected in order to clear out the com,puter. The computer will disable the a/c compressor when the system loses its charge. You have to either clear the low charge code out of the computer or unhook the battery for a minute. You can hold in OFF and WARMER at same time on the climate panel and see if you get any A/C codes. Do this with key on, engine off. To get dash back to normal press auto or turn off ignition.
== == == == CHECK THAT CLUTCH IS TURNING, YOU HAVE POWER TO COMPRESSER.
The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
read the manuel but it's wrong since I did and it still will not come out!.no help on the internet including here.
Could be a collapsed lower radiator hose, perhaps a bad thermostat.
you still have a problem the light only comes on when it stores a current code
If you are talking about a 2000-2005 Cadillac Deville DHS and DTS it would be just a trim level. DHS stands for Deville High Luxury Sedan and DTS stands for Deville Touring Sedan. The DHS had some extra luxury features the DTS did not, but the DTS was still a more pricey trim level with a higher output Northstar V8, 17 inch wheels, floor shifter, bucket seats and a firmer ride. All things the DHS trim or standard Deville trim did not have.
i got a 1993 Cadillac Coupe Deville and my turn signals was doing the same thing and I got new bulbs and still didn't work. I had to get a fuse to make them work
you need 2 check the oil 2 c if its still good. then go bac and try it.
Throw it out
Ignition Key switch is bad.
Bad flasher.
No, my dad has a 2004 deville and its given him nothing but problems. Good thing its still under warranty. Transmission problems, computer problems and a bunch of other things. Once the warranty is up the car is gone.
Check all your accessories pulled by the belt. There are a lot of bearings in these accessories that can cause the " chirping noise".
