Dorman 599-211XD Patended Climate Control Module with Automatic A/C Controls Assembled in USA Compatible with Select Models (OE FIX)

2003 Sierra.....Driving down the road and my screen went dark. None of the buttons for defrost or AC would work. I ordered this part. It was super easy to install and solved the problem. My display was really dim for years and I just lived with it. This new module is so easy to see!

Usually dorman is a good product but I should've accepted the reviews. Product configured correctly and seemed to work right at first but then it didn't. Didn't come close to operating like the original, which only problem was the temp numbers jumping around when trying to change the temp. So I put the old one back in. From the time I turned on the key it would blow full blast until I manually had to cut it down. The dual zone wouldn't work right. Would have them both set to 70 and then start turning the temp up on the driver side, all it would do is cut the air flow down on the driver side but still blow cold. Only way to get any heat was to cut both sides up. When keeping the settings at my normal 70 for both sides it still tried to freeze me out. Only up side was the panel was new and bright. The down side to that is that it was too bright. It didn't match any of the other instruments and when you adjusted the dimmer it only made it harder to see the others.

I did not realize how bad my old unit looked until I got this new one. What a difference!The OEM unit had lost all of its lighting and I purchased an LED kit to replace them myself. However, after replacing the bulbs along the bottom none of them would light. Double checked my work, added power manually to each bulb, to the string of bulbs, and no matter what I did the LEDs would not light when plugged into the car even though they worked fine during manual testing.So after a couple of hours of frustration soldering and resoldering and testing, I threw in the towel and purchased this Dorman unit.It immediately came to life and appears to work exactly as they old one did, except it looks brand new and now lights up! I did notice the buttons are a bit stiffer than the OEM, but the OEM was 16 years old with over 260,000 miles under it, so maybe they just got "softer" over time?Well worth the money.

Got it in a nice packaged box fit as it should seems legit buttons all work good and feel nice has white back light which is nice and clean works as it should no issues the screen is a little odd to me had faint red lines in the background I’ve seen some comments and pics about it mine is not bad at all just a little noticeable as long as it stays that way and works good I’m cool with it for the price beats double the price for a new one but it works fine if anything changes I’ll update the review so far tho I’m happy with it I’m sure a lot of comments are like anything just a bad batch here and there unfortunately I recommend it

Update: 3-4 weeks after install, its 17F outside and my truck has no heat. The unit lights up, the temperatures show they're adjusting, but no heat or air is coming out any of the vents. Also the rear defroster couldn't be controlled with this unit anymore. I checked fuses, restarted the truck a few times, all fuses were good. I reinstalled the original OEM I'd swapped out and BOOM heat works just fine! The original reason I switched the unit was because my backlights stopped working, but the controls always worked just fine. Needless to say, I'll take no backlights and heat in the truck any day over a unit that looks good but doesn't work. Note: I canceled the insurance policy too as I won't be requesting a replacement if this is the quality I get out of the box.Works perfectly so far for my 2003 Chevy Avalanche. Pop the bezel off the dash, 2 screws and a few clips and 2 plugs. Literally 5 mins to install! I did order the warranty as another reviewer suggested as electronics rarely fail immediately but I paid $19 for a 4 year warranty just in case. The only thing is the lights are WAAAAY brighter than the stock unit, though only 50% of the lights worked on the unit I swapped out, hence the swap. So far, I’m impressed and I’d recommend it—also, can’t beat the price as I got the unit for $119!

4 stars because of the service, 1 star first the one, lasted a couple of weeks, the display and buttons stoped working, factory defect, (display went blank). BUT they sent a new one and so far it's working fine.

The part is fine works as advertised

This has been installed in my 2005 Tahoe for almost 2 years, about a year ago the display started getting dimmer. Now it it basically unreadable. Worked well initially but now it has some quirks. Possibly failing completely.
