Drivers side brake light and horn won't work,,is it the multi function switch? 1999 chev blazer 4x4 . if so how much does a new one cost?

  • Anonymous May 13, 2010

    thx for a reply but, it's not the light,,it's in the wiring and the horn will NOT work at all, the guys checked it out and tell me it's a multi function switch at an outrageous cost and I need it fixed to pass the safety for my new playes and sticker.

    It seems like you might be dealing with an issue related to the multi-function switch on your 1999 Chevy Blazer. To get a better understanding and find out the cost of a new one, I recommend reaching out to RockAuto customer service . They can provide you with the necessary information and assistance to ensure your brake light and horn are back in working order. Good luck with your repairs!

Why does brake assembly fail when I press pedal?
Check for loose contacts or wiring that is causing a short circuit near the brake pedal, or at the rear light.

I have a 1990 Mercury Cougar. Several problems...Blinkers, hazards, horn, and break lights are not working. However the break light in the back window comes on when the break is pressed. Checked fused and...
I am unaware of what a "CO" display is.
Now with the blinkers, hazard, horn and brake lights not working that may be the multi funtion switch (blinker switch) that is located inside the column (where the blinker lever attaches).
Obviously the blinker, hazard and horn will all work off of something in the column. Brake lights, you may think a switch on the pedal.

the brake lights do work with that switch but when you have the kind of tail lights where a turn signal light shares the same bulb as a brake light, the brake light is cancelled for the turn signal by running through the multi function switch inside the column.
The third brake light does not blink so its not on that same circuit.

Replace the multi-function switch in the steering column. The 3rd brake light is powered directly off the brake switch while the regular brake lights are wired thru the turn signal switch. Common problem

How do I change the turn signal switch?
the turn sigal switch is in the multi function switch system. you will have to pull the steering colum apart to get to it. first pull the bottom part of the colum shell and see if it will sneak out that way with out complete dissasembly.

Have a 99 suburban 4x4 , all three back brake lights do not wrk
I was having the exact same problem as my brake switch was fine on my 95 suburban. However upon further inspection the problem was very simple i felt really dumb once i found this: the wire harness that comes away from the switch witch is a bundle of white wires that comes down and across the under side of the steering column had 2 damaged wires upon repairing this i have had no problems since then feel free to email me on this problem at [email protected] as i will do my best to help u out. But the problem is most likely a wire short out, or damaged wires for the normally open circuitfor your brake switch.

Wiring in back brake light not working
Hello,
If you are driving a S10 Blazer you may have trouble with the turn signal switch also known as the multi function switch. this switch feeds the rear from the brake switch. some times it will work if you fiddle with the hazzard button.

I lost my head lights, dome light, horn door
sounds like you have a bad ground somewhere. Check every ground strap that you can find, make sure it's tight, and not corroded, etc. Sounds like the accessories are trying to find a ground, and going through the brake light to do so, thus burning out from too much current.
