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)
