Looks like there is a shorted circuit somewhere. Sometimes there is excessive labor involved to remove components to get access to wiring under the dash.
Did you get any aftermarket accessory installed prior to the problem?
No aftermarket accessory has been installed. I think that the dimmer switch has gone bad. I tried to buy a new one on the way home from work. But, the dealer needs the VIN for that part. It is never simple with this car. Thanks for your help.
