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

The module is made of a lighter material than the original and therefore requires TLC for durability. All functions work well and setting 5 for maximum air conditioning works much better with this air conditioning control module. It no longer worked on the old existing module. The AC ON and recirculation buttons are more responsive to presses than to a quick touch of the button, as it sometimes didn't work. The new dash looks out of place on the old dash, but it's the second step in Tahoe's update after eBay's new LED dash lights.
