I've been living with this, but for quite some time (a couple years, anyway) my heater motor will cut out when I hit a bump. It might come back on in a couple blocks or maybe the next time I start the van. It has variable speeds (at least high and medium). I've seen other threads regarding relays, breakers and motor replacement, but I can't seem to find anything specific to this intermittent operation.
I have smelled "old mouse" in the past, but not for a couple years (this van stays in CA and is typically not driven for half the year). I have had the dash off to replace a wiper motor, so I could get in there and inspect the ducting/blower housing, but I'd just as soon not.
There is a fair amount of rust on the vehicle, so grounding could be suspect.
Does anyone have any ideas? It's always nice to have a target.
Thanks,
Scott
