Question about 1990 Buick LeSabre

Lost turn signals, hazards, and brake lights

After jumping the car I lost all turn signals, hazard lights, and the brake lights on the rear, but I have the brake light in the back window. Also I have lost power to the radio. I have checked fuses and they are fine.

Sounds like you burned a fuseable link wire. Some of the circuits are protected by a fuseable link in addition to the regular fuses you can see.
Check the wires at the starter with a test light or meter - one of them may be burned inside.

SOURCE: No turn signals

Have you tried replacing the flasher? They're typically round, and with the fuses under/in the dash. They probably cost 10-15 bucks, usually available at your local autoparts store.

SOURCE: 1995 buick roadmaster

this is a common problem with all GM cars.

It is not your fuse or the power, it is in the column.

Pull the removable cover from under the dash to expose the column,
you will see a long plug with a crazy amount of wires going into it.
pull the plug out, and make sure there is no debre in the plug, or dried out grease.
while your looking make sure no wires are burnt, singed or cracked.

If this does not work, then you may have to take it in to have the wheel pulled so the components and wires can be chacked in the column.

If you can shift the car out of park without pushing on the brake, this is definatly your problem.

check for faulty signal light flasher located under L/S dash. Separate flasher for hazard lights and signal lights.

Your Hazard switch is bad. There were a bunch that had faulty soldering connections, and would fail prematurely. This circuit also competes with the turn signals, and the brake lights. Replace the switch with an aftermarket replacement, and it should fix your issue.

No brake/hazard lights,have running/turn signal lights

Suggest you change hazard flasher 'can' first, then go to the hazard switch. I'm betting it's the flasher can.

1995 C1500 Cheyenne flasherstat stays on

I was having a similar problem due to a damaged hazard switch until I finally lost all lights. You might try to use electrical contact cleaner blown down around the hazard button on the column as dust can collect causing a short. The contacts are on the right side of the button. Replacing the whole switch was my only option due to the extent of the damage though.

No rear brake light / turn signals on 2001 Chevy Cavalier

The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores
