W124 heater
W124 Coupe 1994
I can’t turn the heater off! I have checked the duo valve and it shuts fine. The power to them (with the heater control at minimum) is 12v for the 1st few min but then comes on and off allowing heat through!
Where do i look 1st - I have checked the inside air temp thermocouple and it’s fine?
Thanks
Geoff
