Dorman599-210XD Patented Climate Control Module with Manual A/C Controls Assembled in USA Compatible with Select Models (OE FIX)

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.

. This one is tighter controls and all the lights work, it controlled the temperatures perfectly on both sides of the vehicle. UPDATE: the passenger side slider for temp adjustment fell off, nobody abused it and as a matter of fact I hardly have a passenger in the vehicle. I slid it down one morning aand noticed it was sloppy, then it fell out. Dorman needs to stop following the crappy manufacturers and get their quality control in order to make sure We the people are not buying junk repeadely for no damn reason other than to line their pockets with our money. Now , the whole unit stopped working except for fan speed control. The Rt temp is stuck on hot the left is stuck on cool ??? No defrost light no nothing.These are just poor quality the sliders are held in with plastic glue or something ??? Just garbage !Where can I get decent quality ?

Got here on time didn't end up installing because the rear defrost botton didn't work and was refused return

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.

This thing worked on 03 z71. Easy to setup. Unfortunately this did not fix my issue with only have Ac fan blowing only on high fan settings. Turns out I need a AC Fan blower resistor instead. Otherwise I would recommend it.

impressive very good product 10 out of 10

Easy install and replacement after a short time putting unit in the dial to select air speed has stopped working. Def not made to last. Equipment has completely stopped working
