I would like to get and Elect.digram 1999 Grand am. I want to fix it my self/cooling fans I mean
cooling fans quit working , dash lights work but none of the gauges worked at all ck the fan motors they work but have no power to them.some times they would come on but not any more pooh . what to do ?
Check the relays in the underhood fuse box. If it's like my '00 Grand Prix there's 3 fan relays. One for each fan then a third for high speed. Set the climate controls to max a/c and the blower on #1. As soon as you start the engine the fans should start. Now tap those relays with the handle end of a screwdriver. If the fans start, you've got a stuck relay. HTH. -Jim
