Start:

The tailgate on this GM truck would not open.

We could feel that the right side would release, but the left side was jammed.

Removing The Plastic Trim Around The
Tailgate Latch Release Handle:

Removing the trim ring around the Chevy or GMC tailgate handle is a tricky job. There are 4 catch tabs molded into the plastic, and these tabs are easy to break. This trim ring is only available at the dealer, so it's not cheap!

Removing the plastic trim ring around the tailgate release handle was the trickiest part of this repair job.

I slipped a plastic putty knife under the edge of the plastic trim ring. I pushed upward on the plastic putty knife to release the catch tab.

Then I inserted a regular metal putty knife under the trim ring, at the corner. (I wrapped masking tape around the putty knife to prevent scratches.) I carefully twisted the metal putty knife until the corner of the trim ring popped out.

 

After I released both bottom tabs, I pulled the lower edge of the trim away from the metal.

Then I pried on the top tabs.

GM Truck Tailgate Release Handle:

When the handle is lifted up, there are two black metal "ears" that get pulled together.

Each ear is connected to a long metal rod, which operates the latch at the side of the tailgate. A small plastic "clip" secures the rod in a hole in the ear. On this truck, one of the plastic clips had broken off, and the rod just fell out of the hole.

 

This is the small plastic clip that holds the rod in the hole. This part cost about $1.40 at our local GM dealer.

There is a small ridge of plastic (red arrow) that keeps this part in the hole. If that ridge gets worn down, then the rod could fall out of the hole.

If this part is kept lubricated (with white lithium grease, for example), then there should not be any problems with wear and tear.

...then I rotated the clip until it grabbed onto the rod. Plastic clip on latch rod, GM truck tailgate.

 

Inserting rod into hole in handle. I inserted the end of the rod into the hole in the metal ear.

This wasn't easy. There's not much room behind the "ear". I used a pair of bent needle-nose Vise-Grip pliers to hold the rod while I positioned it behind the hole.

 

To get the rod fully seated in the hole, I used a long pair of needle-nose pliers to squeeze the plastic clip against the metal "ear". Securing rod in handle, GM pickup tailgate.
