CEL on with lights off, CEL off w/lights on? No codes, runs fine, gas cap on good, nothing looks out of place under the hood. If I use the dimmer the lights and the CEL seem to be inversely proportional to each other. Any ideas? :banghead:
yes. there is a short to the light with the switch. specially since it works with dash dimmer.
The CEL(SES) uses a Negative trigger. The dimmer is a positive slider switch.
On Gen 4s(my car) its a Dark blue / white stripe wire for the dash lights. Give us a year to work with and I will tell you what your CEL wire is .
Sorry thesavo, I didn't get an alert that some one answered the question. It's a 2001 taurus with auto lamps. Do you think it's in the light switch and not the cluster? Could it be caused by a burnt bulb in the cluster? Or am I about to start on a cable chase and wire hunt?
Thanks for your patience,
