I have a 94 Sierra - rear lights- (blinkers/reverse) not working/cutting out when brake applied. have checked fuses & changed bulbs

Asked by Jul 17, 2014 at 09:29 PM about the 1994 GMC Sierra 1500 C1500 SL Standard Cab SB

Question type: Maintenance & Repair

after using my flashers/hazards - im having rear light issues...blinkers blink super fast (replaced bulbs & fuse is fine), if left blinker on, when brake applied right one blinks, or all lights cut out when brake applied, no reverse lights...but have parking lights (until brake applied then cuts out). I do most of my own maintainence on truck but have never had to deal with electrical and am at a loss - any ideas?

1 Answer

The only other time I have seen this is when led lights where used in place of the regular light. It causes some sort of back feed. Make certain you have the factory light for each socket. Aside from that..... I would look at the multi function switch and just wiring.
