on the back of he dash those was bad to short out and cause this problem to happen ,its best when this happens to replace the dash as a whole unit rather to try to repair that one,i own a 2001 model and all my gages went to full including the gas gage in it and it was a bad dash that was causing that to happen,you can get a good used one for 50 bucks at any salvage yard these days ,good luck.
