Question about Chevrolet Blazer

Sometimes when towing my trailer with my 2001 blazer stepping on my brake pedal causes the dash lights to shut off? This only happens with the trailer hooked up and not every time. Any ideas?

2004 Chevy Blazer stays running when shut off if your foot is on brake. Can even take key out.With ignition off stepping on brake turns gauges and radio on.


There is definately something shorted to power through the brake lamp circuit. If you have any aftermarket equipment installed on your Blazer, I would recommend un-installing it. I have seen similar problems caused by aftermarket alarm systems, remote starters, etc.

I DID do a search for possible Technical Service Bulletins (TSBs) for your vehicle. There are many TSBs published for known problems on your vehicle. However, there are NONE that apply to the symptoms you are describing. If this is not being caused by aftermarket equipment, then some serious electrical diagnostics needs to be performed to find the actual CAUSE of the problem. It could be anything from wires that have rubbed together in the wiring harness to an internal fault in one of the computer modules.

My brake lights don't come on when i step on the


check the microswitch on the brake pedal, you should be able to see it under the dash by the peadal mount, if you can chage it or test it yourself then try, but only if you can see the plug/soket join on the lead. If not then ring an auto-electrician & have them test it.
Hope this help's

Trailer brake controller problem


I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.

No brake lights , everything else works


Sounds like your brake light switch, located on the brake pedal, has gone out. Shouldn't cost to much at auto parts store. Thanks for using fixya.

Turn signals 2003 Ford F-150


Sounds like the turn blinker is shorted internally. Suggest you change it out, to test this.

My next check is that no wiring is melted and burned, such as can happen with any connection to tow a trailer. U-Haul has fine print that indemnify them of any problems they cause! have you towed anything recently?
