2013 GMC Sierra 2500 HD Switches

Genuine GM switches for the 2013 GMC Sierra 2500 HD, at wholesale prices. Switch part numbers split on trim, door position and whether the vehicle has express up and down. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Signs it is time

A window that only works from one door, or a switch that sticks. On a heavy duty pickup, box length and cab style drive more part number splits here than the engine does.

What you get ordering from us

• Factory sourced. These switches are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical switches numbers for you.
• Ships from Dallas. Switches ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on switches that did not fit.

Making sure it fits

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
