Looks like our 98 ML320 just went into "old age" failure mode this weekend - the ventilation system just started blowing out a acrid electrical burning smell.
Fuse #44 blew, and the wipers stopped working along with the power mirror adjustment. The AC blower motor still worked fine!
I suspect either a bad resistor array for the AC system or perhaps even a bad wiper motor - there was a wisp of smoke coming from under the plastic cowl cover at the base of the windshield on the DS next to the WW jet.
I checked and replaced fuse #44 and all works as NORMAL again, except I get the strong odor of burned electrical components.
Anyone have any ideas? Anyone tackled changing the wiper motor or AC blower resistor array? I don't have a shop manual, so it's pretty exploratory - I have no problem working on cars (have 3 older Porsches to keep that skill in line) - electrical or mechanical. Let me know what's involved, your experiences.
YIKES!! Just checked a source and it quoted 15.5 hours for Re&Re of the heater case assembly!! Hope it is not the resistor array!
WW motor is a 2.4 hour replacement and looks like the motor costs $34.50!
Thanks to all in advance! These forums are a godsend! []
