My 93 suburban brake lights don't work. My radio doesn't work. The clock is stuck on 1:00. My AC is hotter than the heater.

My parking lights/turn signals/back-up lights DO work.

Any clues??????

I have a 1996 Chevrolet Suburban 1/2 ton-2wd with the following issue: I have NO turn signals at all and the 4-way fuse blows when I hit the switch. I replaced the trailer plug with a new one and the 4-way fuse quit blowing out. ALL other bulbs, the combo flaher & fuses are all good. I have narrowed it to the multi-switch on the column. Is there anything else I need to check before buying this $150.00 part??

1999 GMC suburban. Indeed, check out the relay on the lower left side of fire wall. About a 3x3 inch block with several other relays plugged into it. It has the # 7866 on it and some how controls the low beam head lights. After spending about $600 2 years ago on a smoked multi-function switch, the dealer wanted to spend another 600 to replace multi switch. #7866 relay has either dirty terminals or has just gone bad. High beams worked but when multi-switch used to dim headlights, no low beam. Mechcanics don't seem to know about this #7866 relay......

MY 2001 Silverado is acting strange. 3rd brake lioght works, parking lights work and turn signals and hazards are fine. However my Brake lights don't work after my trailer harness got filled with water and shortder out. I cut out the trailer wiring, and the brake lights started to work again for a day then stopped. All the bulbs and fuses are ok and new, I'm getting power to both fuses, and the brake switch checked out. But the Main brake lights will not work!

There is a plug underneath the rear of the car. Make sure it is still plugged in.

I have 1999 suburban and the tail lights mysteriously quit working from time to time. Last night the tail lights, hazard lights and the blinkers quit then while continuing to drive the blinkers and hazards started working again. Does anyone have any ideas as to what may be causing this? All suggestions are appreciated.

1997 Mustang Brake Lights Not Working. My High Mount Brake Light Works. Someone said it the Multi Funcion Switch. The Only Switch I see as the Switch is the Turn-Bright-High Beam? Is this the one I need? Any Assistanc is most appreciated.

I just bought a multi-switch for about $75 after postage on Ebay. They are new and widely available there. They also come with the wiring harness.

I have a 1999 Suburban. At first I taught I had a bad bulb, because when I turned on my turn signal to the right, I got a rapid signal. The bulb is fine, but I get no signal or brake light on the right rear. The front signal does flash, but very fast. Also, the parking lights work fine. Does anyone have a clue, because I don't.
Thanks, David
Have identical problem. Working on now....t

Hi David...there is a connector in the rear ...under the bumper that is for your towing lights. Go to walmart and spend $15 on a new one. These things go bad all the time and cause this problem.
where is the conector at is there a part number
