Re: Turnsignal problems

If the light is on and but not blinking (dash green light), you have a bad bulb or ground somewhere.

Re: Turnsignal problems

Slick. The more wierd an electrical problem seems to be, EG, multiple systems affected as opposed to 1 thing not working, the more likely a ground problem exists. Check your grounds out back first. You replaced the license plate light so probably had to move the rear lighting harnace. Check the plug between the body and rear lighting harnace. This is a common failure point. Look for ANY green deposits in or around this plug. Next, if it has a trailer connection, look where it splices into the rear harnace for any green again. Repair the wireing as necessary and use heat shrink connectors wherever you have to resplice. jim

The worst thing you could do is get into my sights, but that don't matter, you'll never know it, cause you'll never hear the shotJim or Paladin whichever you choose.
