This has been found to be blown and the car not starting. This happens after the car has been run and wacky temp and gas level readings observed. Also on board computer goes out. After the fuse is replaced all is fine. Car goes 1 miles to work and back everyday with weekly exercise; problem is new. I will not try to use defective blower or dome lights and see if fuse blowing stops. Where does one start tracing intermittent shorts on an electrical system. I know I have alot of homework to due but thought I would start here.
