Volvo Climate Control Unit Up for sale is a Volvo climate control unit. Volvo made several types of these, I probably have the one you need listed. This is in good working Condition, removed from a recent crash damaged car, and comes with a 30 day warranty. Part number is 3522159. Check the part number off your original to be sure if this is right for your car. These parts are insanely priced at the dealer, and are still a lot of money for a remanufactured unit. this is about as cheap as you will find for a correct unit anywhere! This is a very good item to use or keep as a spare since these units are so expensive!! A faulty one can be noted by the climate control being stuck on one position regardless of the setting on the climate control, also by buttons that don't function or stick.
