- 1989 W124 Estate, rescused after standing 14 months with a blown engine!
I have a 1989 W124 estate, last week the air coming into the car from the heater is always hot, when i turn the heater control dails down to cold it makes no differance. Is this a duo valve issue, if not any ideas before i start investigating,
