Tanin Auto Electronix started repairing and selling GM and Chevy Truck climate 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 truck came with a traditional manual climate control. 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 climate control units 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 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 service is performed at an additional cost.

We designed and manufactured a brand new “blue” lens that is in the center of the automatic climate control unit. These often break, crack, become scratched, hazy, and distorted. We will advise you if this is needed or you can request it.

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. We are currently in the process of re-creating this button and offering it for sale and with our rebuilds.

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.
