have a '93 gmc Safarithat has developed a couple of electrical problems.
- Periodically the battery just goes dead overnight, the doors are properly closed and there is no detectable electric usage. any ideas?
- both brake lights are not working, i don't know much about ele4ctricity but I did check the bulbs and the fuse (15 amp) all are good. I changed the pedal switch and still no change. Please help, we need the use of this vehicle!!
- The cruise control doesn't work and I don't know where to begin with that, sio if you have any ideas keep the term9inology explicit and simple.
Thanks, jac
