Has anyone had any issues with this. I have a 2004 Range Rover HSE. My Ac unit wont no matter what. If the car is on and im drving and I turn the fan speed all the way off it sounds like it is still running in defrost mode ( threw the vents) then when i get out of the car and turn it off it is still running. I have to pull the first 50 amp fuse to turn it of so my battery wont die. I think it may be a blower motor resistaor but im not sure. Also my battery light is on after i changed my battery out. Is there a way to reset this lite?Any helo will be greatly appreciated.
