I thought it was the relay, I've never heard of both bulbs going at once. Ground is fine. The guy at the part store said bulbs, but they are fine? Thanks, DJ
Yes my left turn signals front &rear flash fast. Turn on hazards there fine? on 1998 GMC Jimmy
If you have replaced the signal light flasher (?) and it's wired for towing look there as well...! Turn the headlights on, if it stops flashing it's a ground problem. If not it's a flasher problem! Does the left indicator in dash show at night with 'park' lights on olny? I dont mean if you turn on the left signal but just the park lights, is the left indicator showing AT ALL?
