instrument gauges out except tach, horn doe not work.
2005 Pontiac Sunfire coupe
The tach is the only gauge that works , all my warning lights work, my horn is out. The alarm is disabled, the keyless entry is out - this is the way I got the car. (When questioned the original owners, keyless entry and horn stopped working before the gauges and the gas gauge went out last just recently.. Also the key fob has no battery but it stopped working before that. Thought could be the instrument cluster for the gauges - but how about the horn and rest? Also noticed my low beams are really dull like my daytime running lights - my high beams are fine-think it is related?
Any suggestions as to how to approach solve and repair these problems will be greatly appreciated. Aloha from Hawaii, Joseph
