This is one refurbished 2003-2004 Chevy Trailblazer and GMC Envoy automatic AC control module. The backlight bulbs have all been replaced and the temp switches have been tested.
This will also fit 2004 Buick Rainier and 2003-2004 Oldsmobile Bravada.
If you have problem with blend doors, air not going to the correct locations, hot and cold delivery problems then the issue might be your servos in the dashboard. This is typically NOT a problem with the climate control.
We rebuild or replace climate control buttons that fail. Common issues are not being able to select the temperature or the dials go past the temperature that you select, or the temperature jumps around. We also replace all of the light bulbs in the unit and repair any issues related to the display failing or going dim. We use OEM GM original climate control units so the fit, finish, and function will be exactly like your unit.
Please keep in mind that these are previously used units, so there may be lightly worn buttons or minor scratches from normal wear and tear.
