The switch broke on my Sierra neb2 - Cars & Trucks

Duplicate question.

Test voltage on wires when use brake pedal, if you have voltage, could be some harnesses go to bad, or, somr broke wires.

Sounds like someone was installing a new stereo. The entire turn signal switch will need to be replaced. They call it a combination switch. You wil need to remove the covers on the steering column, and unbolt the switch. The wires do not unplug from the switch, and must be disconnected at the junction block beneath the dash.

It is the switch or you have a presure line undone or broke. The switch is is easy to take out. It just disconnects at the back when you get it out.

disconnect neg battery terminal -remove steering wheel will need a puller some auto stores let u borrow these tools -remove turn signal switch not necessary to totally remove switch pull far enough rearward to slip over shaft but dont pull harness out of column --turn key to run -remove the lock retaining screws dont drop into column -remove lock -screw torque is 40 inch lbs for reg column 22 for adjustable column

go get a replacement, say it was defective.

Check if there is no power at the bulb socket or check all the fuses, if they are good you have a bad backup light switch, are a broke wire.

I have the very same problem, no seat heat on either side and no power seat control on the drivers side. anyone know which fuse or switch operates the drivers side power seat? Thanks

i just changed my unit on drivers side door man it was a pain well first it started off with not going at all i thought it was the motor but motor was good the wire was just getting hung up because the plastic piece broke on the track,so first disconnect motor from track and hit switch to see if it turns,and if not then replace motor,be careful not to loosen the cable.you almost need it exact tension for the track to work right.
