I got a 95 GMC sierra full size pick up.....I know when my blinker blinks really fast one of my bulbs is burned...so im driving and sure enough it happens so i go to replace the tail light bulbs..but by the time i get home the signal light is working just fine again...this happens like twice to me, where im driving it blinks real fast like it isnt working...then 5mins later its working normal again.....i went ahead and checked the bulbs and to my surprise they are all good, but i replace them any way. All was good then it did it again yesterday. The bulbs are good yet it still messes up every once in a while....Loose ground somewhere?

 

do both blinkers blink fast or just one?

 

I had this happen on my 97 Suburban. Turned out the place in the harness where I plugged in the trailer wiring adapter was coming loose. Check that connector.

Fix ya right up

 

most of the time its the circuit board that the bulbs plug into. you can pick them up at about any parts store.

 

Could also try some bulb grease (dielectric grease) on the contacts. Lube them up good, kind of sounds like you have a bad or worn socket.

 

WERD....thanks guys...i think it was my connection where the lights split for my trailer harness.....cause i hooked up the trailer to it today to move it and **** went hay wire...lol...and the connection felt hot...so i disconnected it and cleaned everything off and reconected it...seems to be fine now.

 

Good to hear
