F*CKING BLINKER.

[94bowtie]

For the longest time, the right turn signal in my 94 C1500, blinks like it has a bulb out. (really fast) Ive replaced all of the bulbs, and even the board in the taillight. Nothing has changed. My left turn signal is working just fine. But when I hook up to my trailer, it blinks like it should. Could someone help me out before I snap and start breaking stuff? haha PLEASE. Because it honestly drives me crazy. I just quit using my right turn signal because it made me mad. lol. Oh and i checked all the fuses (i think)

Trace all the wiring and look for corrosion, then splice in replacement wire as necessary.

if it works fine with the trailer harness plugged in then maybe something is wrong at the harness on the truck.

where are the grounds located for the turn signals?

Yeah sounds like the ground for your taillight is bad, but then when a trailer is hooked up it uses that harness's ground.
