SOURCE: 1998 gmc sierra brake lights

did u check that they not burn?if not you should Check the wires going into the steering column if you don't have separate turn signal lights and brake lights because if they use the same bulb then the turn signal may be bad. If I remember correctly that particular car doesn't work this way, but I include it just in case.

SOURCE: gmc sierra turn flasher location

The flasher on this vehicle looks nothing like the flasher's of yesteryear. It will be located behind the drivers side knee bolster(under the steering wheel). It will be a small black box that is about 3 inches wide, 2 inches deep, and 1 inch thick. It may be somewhat difficult to locate because on some of the GM trucks they actually hide it behind the guage cluster bezel but to the left of the guages. Let me know if I can help you any further.

SOURCE: 2000 GMC Sierra left rear door

Hello,

You may have 2 issues going on at the same time.
1. The child lock safety latch is up, preventing you from opening the door from the inside.
2. The inside clip to the rod that opens the door from the out side could of come off from closing the door to hard. Or the lock itself is getting stuck.

Options:
Roll the window all the way down, and look through the window crack with a flash light and see if any of the rods are just hanging and not connected.
If there are you can try using a slim jim with the cut out part facing up and try to catch the latch and pull up this could open the door.

Or you can try to take off the door panel from the inside, however this is very difficult and should be done by a professional becuse you don't want to break any thing or cause more dammage.

Once the door panel is off you can then pull the inside door release rod and open the door.

One more thing you can try: Pull the inside handle and the out side handle at the same time while having some on pull or push on the door, it just might be stuck and need a little force to open!

SOURCE: 1998 GMC Sierra Signal Fuse Blowing

it seems you have a short in either one of the lights or interlock. all are connected to the same fuse. trace the wiring from the fuse box back to the component. Using a test light test in between the wires. check for any obvious breaks in the wiring.

When turning on left turn signal, the flashers come on, when turning right only the right flasher works.Automatic door locks work intermittently


you have two problems the flashers are shorted. I would check the wire harness at rear off the truck. Possibly a trailer light harness has shorted at the plug most of these can be taken out of the harness and the two ends will plug together without the trailer plug.
