Does anyone know what color the hazard light wire is coming from hazard switch on 1996 gmc sierra?

Wiring in the steering column to the switches in the steering wheel may be compromised, or the switches are possibly faulty and will have to be replaced. This is not a job for the DIYer as there is a real hazard messing with the air bag in the wheel.

When you had the wiring loose for multifunction switch, if possible, knowing what color wire did what, using wiring diagram, I believe you could have used jumper wire to bypass multifunction switch to see if this or that system would work, if it doesn't, the multifunction switch probably wasn't the problem. On older vehicles it was probably easier to do something like that. Could be issue with wiring in steering column or clock spring, where applicable.Your low beam from dimmer switch goes through drl relay, with relay not energized. At the low beam head lamp, tan wire is voltage, black wire is ground.

Do you have power in and out of the hazard flasher ?

Jump between the wires at the switch. If the lights come on. Need I say more?

beleive there is a junction box on those models that main tail lights harness comes too then is distributed out in seperate smaller harnesses.

They make harness that plug right into the existing harness on the truck. About 25 dollars. This is your best bet as you wont be repairing them about a year from now and every year after.

If wiring is good also I would say maybe a bad part. The brake light switch is suspect and yes you can get a bad one.
