Any suggestions on what might be causing this?? My dealership wants to replace the whole controller compartment for 2 grand.... I just find this hard to believe when I think it just needs to be re programed.2. CQ Says: y Tag: I have a 2004 Range Rover and my vents in the dash no long blow air or heat!!!?
