The power front seat on my 98 is having problems. I have always had problems with it coming back up from the recline postion. Now it wont move back and forward. It does move intermittenly when I play with it enough. This wouldnt be a problems except my 16 y/o daughter with short legs drives the truck to school often. The truck is currently at the dealer getting a t-belt and valve job. They quoted me about a grand for a whole new system. Any ideas?
