Hi I have a 2004 S80 D5 2.4 . The climate control on the passenger side is really cold but not the same on the drivers side. I have swapped the ECU climate control module. but this has made no difference. I am thinking it may be an actuator that is not closing/opening correctly. Has anyone had this issue and is it hard to fix ( full dash board removal?)
Many thanks
