Question about 1991 GMC Sonoma
I have a 1991 GMC sonoma. My tail light on the passenger side had gotten busted and got water inside. the bulbs blew so I bought all new bulbs but yet it still doesnt blink. just comes on and stays on. the bulbs in the front come on and stay on also. What can I do to fix this?? Is it some kind of relay or something?? if so where is it. Thanks
The falsher unit on these vehicles is a thermal one therefore if the amunt of bulbs in the circuit is reduced then the flash rate is alot slower, remove rear bulb, clean up the bulb holder and the contact inside the holder.
Good luck Davelee
