I have a 97 SL1 which I bought new in Salt Lake City. It had a bad smell
coming from the vents after the air conditioning was shut off. I took it to
the dealer and they put something on it that run the ventilation fan after
the air conditioning was shut off. They told me condensation on the coil
was causing mold, and that the addition would dry the condensation. The fan
would run after I shut the car.

I've since moved to Portland Oregon. Now the fan sometimes runs all night
and drains the battery. (very annoying) I contacted Saturn of Portland.
They have no idea what I'm talking about. I'd really appreciate any insight
anyone has on this problem... how to disable the aftermarket circuit... or
whatever. I'd much rather have the smell than a dead battery all the time.

Thanks in advance.
