Rolled down the window in your 2002-2009 Chevy Trailblazer and heard a loud *CRACK*?

Or maybe the motor is just whining and the window won't budge.

Either way, this ECCPP window regulator and motor assembly is exactly what you need to get that window working again.
\n
This is for the front driver's side (left side, front left).

It's a complete unit—the regulator mechanism and the electric motor are already assembled, so you just swap out the whole thing.

It's a direct replacement, meaning it bolts right in using the factory mounting points and plugs into your existing wiring harness with the correct 4-pin plug.
\n
The regulator is made with stainless steel, and the motor is a direct OEM replacement for part numbers 741690 and 741-690.

It's a new unit, sold individually.

The color is a mix of black and silver, with a smooth surface finish.
\n
A quick heads-up: mounting hardware is not included, so you might need to reuse your old bolts.

Also, double-check that this fits your specific Trailblazer using the compatibility chart.

But if it's the right one, installation is pretty straightforward and gets that window rolling up and down smoothly again.
