had the same thing kinda with my 05 driveing on the high way everytime i went to use my blinkers the light wouldint come on on the dash or the light outside so i messed with the fuses no good, then messed with the hazards and they worked brand new.

 

ok i got the mulifunction switch replaced and i still have the same issue. What else could it be? Help!

 

Pull apart the tail lights and look for corrosion in the bulb sockets.

 

i dont know what your exact problem is but couldnt it be your hazard module as well?

 

ok. just got done looking at the bulbs for corrosion and nothing. what else?

 

Do you have a trailer plug? Even if you do not, check up on the rear frame rail for a bundle of wires tucked up either on top of the frame or in the frame. I am not sure if the trailer harness was standard on a '95, but it is possible that, if so equiped, the harness has shorted out due to corrosion.

 

MY 98 BLAZER'SLEFT TRUN SIGNAL IS DOING THE SAME THING, BLINKS THREE TIMES FASTER THAN THE RIGHT SIDE ?? HAD THE CLICKING NOISE UNDER THE DASH FOR A SHORT WHILE THAT WENT AWAY BUT THE RUNAWAY LEFT TURN SIGNAL IS STILL HAY WIRE , WHATS THE FIX ??CHANGED BULB AND FLASHER, NO HELP

 

Ya you are right. the harness had corrosion all over. So far so good for a whole day. they are operating welleven when i press the brake pedal. thanx. i'll let you know if they stop working again.

 

Did you check your Blinker fluid level????
