1978-91 Square Body Chevy & GMC Blazer Tailgate Power Window Regulator Cable

Restore smooth and dependable operation to your 1978-91 Square Body Chevy & GMC Blazer Tailgate Power Window Regulator Cable. This replacement cable connects the electric window motor to the regulator assembly, allowing the tailgate glass to raise and lower properly. Designed as a direct replacement, it helps bring your factory power rear window back to reliable operation.

The regulator cable is one of the most common failure points in the tailgate window system. After years of use, the cable can become stretched, frayed, or broken from constant movement and age. Even if damage isn't visible, worn cables can weaken internally and eventually fail without warning. For this reason, it's highly recommended to replace the cable whenever servicing the tailgate regulator or motor assembly.

A failing regulator cable can cause a variety of problems, including the window not moving while the motor continues to run, slow or uneven window movement, grinding or popping noises, or a window that becomes stuck in the up or down position. Replacing the cable restores proper operation and helps prevent additional wear on the motor and regulator assembly.

Installation requires removing the regulator assembly from inside the tailgate to properly install the new cable. This cable is designed only for factory power window regulators and will not fit manual tailgate window regulators.
