New to this site and Range Rover ownership. Bought a used 07 RRS for my daughter. Starting getting cooler at night so we tried the heat. No hot air on Drivers side and very little heat on passenger side. Everything blows up or down left or right as suppose to. Just very little heat. Clean the heater core? Would like to know if anyone has information on what each damper/motor is suppose to do. Apparently there are 5 dampers/motors. 2 on drivers side, 2 on passenger side and one on the heater. If I can narrow down which one is not working. Does each side have its own heating damper or is that controlled by the single damper at the blower? Not much info on this out there other than 3k repair price from dealership.
