no heat in my '79 300SD
no heat in my '79 300SD
after white smoke and a burning smell entered the cabin, the heating stopped.
The heating amplifier had burned out.
Replaced.
No heat.
The AC Servo may have been the problem but was fixed by George Murphy of Performance Analysis in Tennessee.
No heat.
The secondary electric water pump may have been at issue. Replaced.
No heat.
Vacuum works to the locks ...
Possibly the interior temperature sensor quit?
The hoses to the AC Servo get hot ... but no heat is being transferred.
HELP :'(
