Review on Dorman 599-210 Climate Control Module: A Perfect Fit for Select Vehicle Models by Luckie Coonrod

This is an obvious aftermarket unit that fits multiple models. Make sure it fits your vehicle. The 2004 Silverado Crew Cab took about 5 minutes to install. I tested the device and everything works accordingly. All headlights work, actuators respond to temperature and door operation, and all fan speeds work. Bring the steering column to the lowest position - remove the instrument panel with your hands (lift and remove) - remove the panel - unscrew the two 7mm screws on each side of the block - tighten the four pins and remove the air conditioning block - separate the block . Reverse the installation order.
