'92 Silverado Blinker issue

Hello....Have a '92 silverado with a left turn blinker issue...It blinks FAST(most of the time with lights on or off)..all bulbs appear OK..The right turn signal blinks at normal speed..Is this wiring or could it be blinker relay?.....Thanks,Pete

I used to have a 89 chevy and the main problem I had was not with the bulbs, but the board the rear bulbs were mounted on. That board has some built in circuits that would rust and fail.

Also, be sure that you check your front blinker and any marker lights or side blinkers.

This forum is for 99 and newer silverados. You may find more help at this forum (http://www.automotiveforums.com/vbulletin/forumdisplay.php?f=1453) it is for 98 and older trucks.
