SKU B001SNYY32 Category


Is your passenger side tail light out? Don’t pay dealer prices to replace the entire tail light assembly. This tail light circuit board by Dorman is an affordable repair option that directly replaces the OE circuit board in compatible GM vehicles.

Installing this repair part can get your tail light working again in minutes compared to the hassle and cost of replacing the entire tail light.

Direct Fit Replacement Tail Light Circuit Board

This circuit board is engineered as a direct replacement for the factory part in select Cadillac, Chevrolet, and GMC models. It matches the original connector type and wiring layout for a seamless installation.

Simply unplug the original circuit board from the tail light assembly and plug this new part in. No splicing required!

With an identical fit and function, this affordable circuit board restores your tail light’s functions just like the original.

Repair Melted or Short-Circuited Boards

Circuit boards can short, overheat, and melt inside tail light housings, causing the lights to malfunction or not work at all.

Rather than spend $500 or more on a completely new tail light assembly, replacing just the circuit board is a quick and cost-effective repair.

This durable circuit board stands up to heat and electrical loads to prevent future failure. It comes with a 1-year warranty for reliable performance.

Easy, Bolt-On Installation

Installation takes just minutes with basic mechanical skills and common hand tools. No need to remove the entire tail light.

Simply remove the trunk trim or rear lamp access panel to gain access to the back of the tail light housing.

Locate the electrical connector on the end of the circuit board. Unplug it from the tail light wires and remove the old circuit board.

Plug in the new Dorman circuit board until it clicks into place. Reinstall the trunk trim and you’re all set!
