1987 300SDL no heat
I have no heat, I've replaced the mono valve and the climate control head unit and still she blows cold. Even on defrost, she's an icy wench.
The climate control head unit is acting weird, it will surge the cabin fan even in the off position. So I'll have to check that.
I can't figure out what is going on.
All I can think is the new mono valve is bad, the climate control is bad, the thermostat is stuck open (even though it runs at 85C) or the water pump is not pushing enough coolant.
I'm open to suggestions.
