First question, does your truck have cruise control? If so, find the cable that goes from the cruise module to the throttle body, and disconnect the cable and see if that solves your problem. Next thing is inspect the throttle cable, from the gas pedal through the firewall to the throttle body, and look for any kinks, anything contacting the cable or linkage.

SOURCE: 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.

Typically the Neutral Safety Switches are located with the gear selector, either in the column or the floor.

Hope this helps,

My 2004 gmc sierra z71 truck the emergency brake handle inside the truck will not release the pedal when applied. When I pull on the handle it will hang there like there is no pulling the cable to release...


You could have a sticking cable to one of the rear brakes. Need to inspect it from below. If you do a lot of off-roading the cable may only need lubricated.
