the brake lights do not come on unless i stand on the pedal. is there an adjustment like the cars of the past ? ( light switch was on a screw and collar setup ? i looked under the dash and only found one switch off the brake pedal. it looked like the cruise switch since it had vacuum lines going to it. or do they use the same switch as the cruise.? if so can you adjust it ?

 

I don't know if they use the same switch, but since the applying the brakes disconnects the cruise control, "they" should be connected...?

Try looking at the Service manuals - the top sticky under General will give you the links to download.

 

There are two power feeds coming off the stop switch one goes to the center stop light the other goes to the BCM.

The stop switch will have a connector with a red wire and two light blue wires.

There appears to be a Stop Switch Adjustment, but I was unable to locate it in the documentation I have.

When you step on the pedal with normal pressure does the center stop light illuminate ?

 

I am definately going to look into this for my issues this weekend.

 

My car is doing the same thing but the brake lights work and the third one stays lit draining my battery...if i take out the bulbs will this stop the drain ? please i need to know thanks ...2007 hhr

 

The brake lights are controlled by a "brake pedal position sensor" rather than an on/off switch of old. Goes through the BCM.

 

ok so theres a problem with the brake switch postion sensor or is it the bcm ?that is why my third brake light will not go off? please i need to know,my car has no warrenty any more

 

Just a update know my brake lights do not light up when i press on the brake pedal only the tail lights stay on and third brake light ...So i go to shut the car off and like there still lit,so i lift up on the brake pedal tail lights go off, or if turn the switch back on the turn signal the lights go off from the auto position not sure on the third brake light because i took the bulbs out kept draining the battery ... Well i am not sure if brake switch is shot or what? if anybody can help thanks....

 

? Doesn't the key have to be in the "on" position for the brake lights to work?
On my 2010 it does. If so, how did it run down the battery?

 

well i found out that my third brake was on when the car was off and im like wtf? So know i tested my brake lights by press on the pedal while the car was started no go ....my tail lights work ,turn signal work ,side makers work,but no brake lights... also found out my cruise control not working ,so someone said it most likely be the brake switch going out ... this making me sick because my wife needs the car for work .. plus with the third brake light staying on it was draining my battery dead, so i pulled all the bulbs out of third brake light sockets the one that's in middle back hatch at the top ....any help?
