Review on Dorman 599 211XD Climate Control Module by Mark Hayes

Do not buy this item! I tried that, ran the program flow twice, which worked fine. However, I sent it back because it destroyed my battery! Somehow it didn't turn off completely and my fan ran at a very low speed, I could barely tell it was on. After later replacing my dead $170 battery, I reinstalled my old OEM box and somehow the returned part reprogrammed something and now my battery keeps dying because something in the system won't turn off completely. I hear a faint buzzing noise under my glove box, which is what the fan motor is telling me. I'm still having trouble filming all of this, but it all happened after installing this part.
