Me too!!! But I knew that, eventually, some one would come along who didn't know the difference between the red light and the amber light.

Maybe the switch for the E-brake pedal is stuck?

I've been farting around with this and no luck yet. I still have not found the parking brake light switch, but it is pouring rain right now and will have to look later. Is this switch up behind something else? Every other car I have ever owned has had this switch out in the open. I'll keep looking.

Thanks for all the replies!

Yes, I do know that the amber light is for the brake sensors, that was the first light I got to go out. One of the wires had rubbed on the inside of the wheel and was shorting out. That is fixed, now just this pesky red "brake" light.

Thanks, Matt

On top of your master cylinder there should be two black caps, make sure your fluid level is full and then push down on both caps several times, this resets the sensor and should turn off the dash light. Worked for me. Hopes that helps.

My God! It WORKS!! Thank you ll for the help. The 2 black "reset buttons" is what did it.

Thanks gain, this site is the absolute best.

Matt

YES!!!
The reset buttons on top of the MC did the trick for me too.

THANK YOU.
