Having problems with your Chevrolet Suburban 1500 ?

I have a 99 Suburban. About a week ago, the two main brake lights and the all hazard lights stopped working. The upper center brake light still works. If the hazard light button is in the on position, the turn signals do not work so there is no blinker activity. When the hazard light button is in the off position, all blinkers work. I have removed the trailer light harness T and replaced the bulbs, and fuses just in case. I started looking for bad/broken wires but haven't found anything.

Hi! Please do check the turn signal/hazard relay. They may be corroded or may need replacement. Hope this helps and thank you for using FixYa!
Does the high-mount brake lite work? If it does, \015\012the problem isn't the peddal switch. If none work, check voltage to and from \015\012the brake switch. Orange wire is hot all the time, supplies voltage to \015\012brake switch. When brake switch is activated, the white wire goes hot, \015\012also, carries voltage for brake lites. \015\012The switch for brake lights that's on the brake pedal. The connector for\015\012 it has two ends. A big end and a lil square end. It has 6 wires on it \015\012the were burnt. Just trace the wires back.

\015\012Does the hazzard lites work?\015\012 Check the stop/haz fuse. Not only check the fuse, use a voltage tester \015\012on the fuse circuit, it should be hot all the time.

Also could check this link REPORTS to find other clues.

I have noticed the following electrical problems with a 2002 Chevrolet Malibu. The hazard lights do not work unless the hazard light button on the dash is pushed down and held continuously. When the turns signals are activated they work sometimes, but may also not function unless the hazard light button on the dash is pushed and held on continuously. The right tuen signal, when it works, begins to flash rapidly when the brake pedal is depressed. When the brake pedal is released, the right t

1984 ford f150 no brake lights. There is a vaccum switch that contacts the brake pedal. It works on positive pressure meaning when the brake pedal is NOT pressed down, the system is sealed. When the brake is pressed down, it creates an opening in the system. I have removed this from the system and it should be sucking air, but I still can't get the brake lights to work. It seems like this is a strange way to activate the brake lights. I wonder if this why the brake lights don't work. I have repl

My 2005 Nissan Armada Reverse sensor system is not working. The button stays in the "OFF" position no matter how many times I press the button.

I recently broke off the hazard button on my 96 chevy blazer. The shop said I would have to order an entire assembly for about $485. Is there not an easier way just to replace the actual button. I slid a piece of paper in between the contacts to keep the flashers from going but the brake lights now don't work. How can I do this?

Battery completely died after car sat for over a month. Hooked it up to a battery charger for a few hours. Went to put key in, alarm goes all crazy, lights flashing, horn honking, etc...

Red button located next to steering wheel blinks during this. Tried the insert key to "On", press/hold red button 3-9 seconds,

Sometimes when putting it into park, the steering wheel will not lock properly, the key will not turn off position and the wheel doesn't lock. The key is then left in the on position with the engine off, but all the dash lights on, as if auto is running. Key can not be removed. This has just begun to happen. It is a 2003 Aztek.As well the gear column doesn't lock, leaving it able to be shifted. Normally you have to have the brake down to shift into reverse, but not with this going on, it will ea
