Review on 🚗 GM Genuine Parts 15793206 Windshield Wiper Motor Transmission (Linkage), 27.9 in - High Quality Replacement Component for Smooth Wiper Performance by Frank Webster

This part fits 2007 HHR. As others have said. No crank (a short rod that runs from the gearbox to the motor) is supplied. You must use your old one. There are other parts manufacturers that include this part but not this one. It's hard to find an example of how to remove it, but it's easy to remove. You don't need the expensive tool they recommend. I used my battery puller (a $13 tool, and the same tool is used to remove the wiper arm from the terminals) to pull the pin out of the old arm and put the new one in, then just manually snap the plastic plug on top. Very easy job.
