Right I have a 2002 1.9i z3 and all is fine but I have a annoying problem.
The cab heater blows cold or very hot there is no half way.
When I first had the car I fitted a new cab heater valve and changed the main radiator and thermostat.
How dose the system set the cab temp is it by mixing cold and warm air or is the another valve in the hot water delivery system I have missed.
Any help please or a link would help.
Fan in blower works at all speeds.
