The heater fan on my '99 9-5 SE (2.3l LPT) has gone intermittant - as
in, usually doesn't run. When it runs it runs full speed, when it
doesn't, I get a VERY low trickle of air from the vents I select.
I can use the ACC to change from floor to dash to wind****eld, and I can
hear the servos clicking and the little bit of air does go where I tell
it. My temperature gage is behaving normally and I have sufficient
coolant. The air that comes out is warm, but there's very little of it.
The ACC does respond normally to me setting the fan to level 1-8 (or
however many bars are on the graph for that) - but, the fan doesn't
acutally speed up.
When it works, the fan starts out kind of growly-sounding. To me, I'm
thinking the fan is going south but, what's the track record of this?
Does this failure mode point more to the fan, or to the controller? All
the fuses are OK, and I've swapped relays around with no change in
behavior.
Thanks,
Dave Hinz
