Turn signals & brake lights

01-06-2016, 09:26 PM
I have an 85 K1500 that I use as a plow truck. I noticed yesterday that I no longer have turn signals or brake lights (tail lights work just fine). I checked the fuse under the dash and it is not blown. Just in case, I replaced the fuse and the flasher. That didn't fix it. I wouldn't think it would be a relay since the brake lights aren't working either.

Are there fuses anywhere else that I could be missing? Any other ideas?

Do the front signals work? Do the hazards work? There may be another fuse marked TURN/BU.

The stop/turn lites in the back use the same bulbs and wiring from the front. Check the rear grounds for those bulbs.

This is out of my '88 manual.

If the front signals work, youll need to check the bulbs too... If one has been out for a while you may not have noticed till the other one went bad.
