basically what it is is my mates car is only blowing out warm air from the heater vents.... removed the glovebox etc and found the problem to be in the motor that is held in with 2 torx screws, does anyone know what this actual motor is called ?? its the one tht goes onto the red arm to change it from hot to cold ! phoned vauxhall today with the part number and everything and apparently they dont know what it is lmao !!
