brake lights & cruise control OUT... but...

Jun 22, 2003 2 Replies

Maybe a coincidence -- brake lights and cruise control are out. First thing I thought was that a defective brake switch was cancelling the cruise. So I checked the bulbs, fuses, and brake switches (both off them). All are fine. Shorting the connections in the cable ends with the switches removed does nothing as well.



I would think that a malfunction in brake wiring would somehow register with the computer. Nope. No dash light indicators at all. Pushing the parking brake pedal does cause the dash brake light to come on. All other lights are fine. ABS seems to be fine.



This is a '98 Pontiac Montana Transport mini-van.



Any ideas?

Check where rear taillight wires ground. Remove screw, clean contact area and terminal, replace screw with stainless steel one, paint over for corrosion protection. Good wiring harness grounds simplify troubleshooting, as the ground is known good. I like the 3rd eye comment, as the 3rd eye would have a seperate ground. Hope that helps.
