ignition/defroster ghost 86 300 E
L6 / 3.0L Gas ,FI, N
This car had a wiring short which toasted some wiring. The previous owner had installed a non MB radio and a CD Changer. There have been numerous problems from this, however the defroster was not affected for 2 years.
Situation; The defroster (wind shield ) only operates normally when the Car is Warm: About 20 minutes.
The problem started when I started using the re circulating function. When cold, To defrost the shield, I turn off the ignition ( key ) when the ignition is again on, the defroster blows for 5 to 10 seconds and stops.
It feels like a relay is opening due to too much demand for wattage. I replaced the ignition tumbler earlier and could correct the problem by turning the key to the â€śsweet spotâ€ť and the problem would be corrected. Sometimes when the defrost is working and I push another button for lower heat, there is no result, I can't turn it off (the Heater that is).
