Thank you for reading this far—it’s important!
This listing is for a repair service, which means you’ll need to ship your climate control unit to us so we can perform the repair. You may notice that the price is similar to our replacement climate control units. However, this does not mean you’re purchasing a replacement—this listing is specifically for repairing the unit you send in. Since there are multiple versions of climate controls, we can’t ship you a replacement unless we know exactly which unit you need, and this listing isn’t intended for that.

If you intended to purchase a replacement unit, please visit our [Climate Controls section] to find the correct one for your vehicle.

If you plan to send in your unit for repair, you’re in the right place—please continue reading. Be sure to click the “What Happens Next?” tab to download and print the work order form and to find our shipping address.

Tanin Auto Electronix started repairing and selling GMC and Chevy Truck heater control units back in 2015. There were two different climate control units offered in all of the 2003 through 2007 GM trucks. The unit was either fully automatic where you set the temperature desired on the passenger side and driver side with two different knobs or the GM truck came with a traditional manual hvac control module. A manual climate control featured vertical sliding knobs for the driver and passenger. These were not temperature-specific, but either “hot” or “cold”. Manual temperature climate control units had a disadvantage because you constantly needed to adjust the knob up or down depending on how hot or cold the vehicle became. The climate control didn’t know what the actual temperature was inside.

The repair process for each of these GM HVAC climate control modules is very different. They each used different bulbs, bulb sizes, and bulb voltage. The disassembly process is also different. Unfortunately, you cannot swap in an automatic climate control into a manual climate control spot. There are other servos and wiring not present in these vehicles that would need to be changed or added.

Our basic rebuild includes all new lighting which is the most common problem. We can repair automatic climate control module knobs that seem to have a mind of their own. Typically the temperature reading will jump around as you turn the knob and is not accurate. This is all covered.

We designed and manufactured a brand new “blue” lens that is in the center of the automatic GM or Chevy climate control module. These often break, crack, and become scratched, hazy, and distorted. We will advise you if this is needed or you can request it. You can also buy our Tanin Electronix 2002 – 2009 GM Chevy GMC Auto Climate Control Blue Plastic Screen Lens

Recently we have seen an extremely worn out left side “up and down” button on the automatic climate control on almost every climate control we refurbish or sell. You can buy our Tanin Electronix 2002 – 2009 GM Chevy GMC Auto Climate Control FAN speed up down button

If you need either the lens or the button we can invoice you after your unit arrives and is repaired.

That about covers our climate control rebuild service. Issues with servos, air blowing out of the wrong vents, or wrong locations are typically truck issues and not climate control issues.
