There may be a short in the front socket. Remove the bulb and inspect the socket for damage. If corroded, clean it up or replace it.

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.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jonathan_3a3c556b4b17d1d2

I have a 1993 GMC Sierra. If the headlight or parking light switch is on nothing works in the tailight assembly. Blinkers work in the front but blink quickly.Replaced taillight circuit boards with new...

I'd be willing to bet your dash lights don't work either when you turn the headlight on.change the headlight switch, it has a short, it's only about 11 dollars at advance auto, and is fairly easy to replace. my 93 chevy did same thing, changed headlight switch, problem solved

Turn signals flash very rapidly. Front lights due not flas while rear ones do. Suspect a fuse. Please help.

If your turn signals flash rapidly that means that there is a bulb out. you said the front do not flash replace the bulb. If that did not fix it then you have a wiring problem that needs to be looked at.

Good Luck

My 1993 Sierra passenger side brake/blinker light didn't work. I took it apart, dug out the hardened [formerly] grease, put in a new bulb and it worked long enough to get inspected. Now it is out again....

These particular year models have a bad habit of the circuit board going out on them one at a time. I would by a new one from the parts house and replace it not a very expensive item.

Rear lights work when turned on. No brake lights or rear turn signals. Front turn signals flash more rapidly. Replaced both rear bulbs with no change

if you're getting a more rapid flash in the front you have a possible blown relay to the back. Check fuses first and see if those are out.

1993 GMC Sierra 4x4, no brake lights, no rear running lights

If you still have this problem maybe this will help. I had to replace the trailer plug on a 93 GMC Sierra K1500 and had a problem with the light's not working. Had to trace wires from trailer plug up to tail lights. The problem was a broken ground wire. It took longer to remove all the tape and replace it than fixing the problem.
