Default full size 91 BLAZER PARKING BREAK LIGHT in dash STAYS ON

I have a 91 full size Blazer and the parking break light in the dash stays on. I took it to Break Check when the light was only blinking and they said the breaks were fine, but in the processes of looking at it the light turn solid and does not blink. They were saying it is probally an electrical problem. Which I hear can be very expensive. Is there anything that I can do?

Default Blazer Parking Brake Light on Dash Stays on

If your Blazer has the Electronic Anti-Lock brake controller attached to the master cylinder, unplug it (both plugs) for about 20 seconds and plug it back in. Sometimes I have had to disconnect the battery and unplug the controller to get the light to go off. I had this happen on my '90 FS Blazer (288,000 mi) and the light would come on whenever it wanted to. I had a trailer connector with a bare wire that would sometimes contact the frame and I believe that caused it to activate the light, but that was not all the time. After covering the bare wires it still comes on, but very rarely. Be very sure there is no actual brake problems before dismissing the light totally.

Thanks for the info Dennis The Menace! I have the same problem with my blazer, I'll try that out and see if that helps. :-)
