Hello,
This is my first post here, but this is my fifth GMT400 vehicle that I have owned, I have this (a 1994 GMC K1500) and another (a 1993 Chevrolet K1500), both are extended cab long beds with the 5.7L V-8 and the 4L60E transmission.
Anyhow, I started having an intermittent issue with the tail lights and blinkers on my 1994 K1500, that had the blinkers start flashing faster intermittently when the brakes and/or running lights were engaged. Now the issue is constant. I have checked the wires coming to the circuit boards on both tail lights, and there is no resistance between the brown wire (which I think is the running lights), and the black wire, which is the ground wire. I even used both my analog and digital multimeters to make sure of the resistance issue.
I am quite sure that the issue of zero resistance between ground and brown wires should not be, does anyone have any good starting points on where to look first, or should I go ahead and use my 1993 K1500 as a "template", and see what the readings are on it, and try to match?
I have a Haynes manual with a wiring diagram for my trucks somewhere, but I seem to have misplaced it. Does anyone have a good, readable wiring diagram that includes the tail lights?
