Dorman 599-210XD Patented Climate Control Module with Manual A/C Controls Assembled in USA Compatible with Select Models (OE FIX)

Fixed me right up. It ran an automatic setup mode when I first plugged it in. Took it like a minute to start working. Kinda weird, but it's working great now for 6 months.

I bought this for my 05 GMC Duramax because the one it came with, the temperature lights had gone out. It seems to work with all the adjustments however it does make my truck throw a code when I use my scan tool.

Perfect fit for our truck

This unit fixed my long-standing problem of reversed temperature controls and inaccurate vent position/mode actuator settings.I have a 2006 GMC Sierra 2500 LBZ. One of the stock climate control temperature levers pulled out and broke. Replacing this with a used factory "compatible" part caused both right and left temperature/blend actuator controls to be reversed. The left blend door actuator was also either full hot or full cold with no mixing. It caused my vent control/mode actuator settings to be inaccurate. I tried the recalibration procedure and swapped out two stock used "compatible" HVAC control units and new blend door actuators with no improvement.After hours and hours of troubleshooting, this instantly solved my problem. I don't know how long it'll last, but for now it is well worth the money.The only con I noticed is I can no longer communicate with or troubleshoot the climate control system with my autel scan tool. This is presumably because the dorman unit has its own internal programming and automatically self calibrates. I'll hold onto my old climate control units and swap them in if I ever need to do any further testing with my scan tool.

2006 Silverado with rear defrost. I had no lights on my old one, so I ordered this. It works perfectly and was a simple install. The self-calibration took less than 20 seconds. My only gripe is that the unit sits a little farther into my dash and leaves a gap between the trim. See photo. That's a stick of gum for reference. Not a deal breaker at all. I can use a washer behind the unit to bring it flush. Overall, highly satisfied and hoping it lasts.

When the unit stops working then you need to unplug so that it can reprogram, and this will fix many of the issues that people are having.

It works but the back-lights are very dim....???

Only had these unit in my console couple of months and the buttons to turn on the AC won't work. And I feel that when I push the dials all the way down for cold it doesn't reach the cold limitI had to put my old unit back in.
