When we bought our 1994 Saturn SW2 while in warranty we complained to the dealer of an odor after running the air conditoner. The dealer installed a device which runs the heater blower motor to dry the heater core area after the engine is shut off for a few minutes. Lately the heater blower comes on occasionally which runs down the battery. Contacted a Saturn dealer about a year ago and they said they have heard of no such device Saturn installed. I would like to remove this device if possible. Thanks

Yes, removing it, or disconnecting it, would be a good idea.

I’ve never heard of this, either, but whoever installed it should be able to remove it.

Sadly, I don’t think there are any Saturn dealers anymore.

A mechanic with a wiring diagram for your car should be able to locate and remove whatever sort of timer was installed.

It sounds like a “turbo timer” or something similar.

The device is called a “delayed blower control module” There is a number 21020418 on a tag added to the power connector to the blower motor. This is probably an after market device the dealer installed since I am told the 94’s had no such device although a Saturn Parts Company on the web says that number has been discontinued described as a wiring harness.

Any suggestions as to where to look would be appreciated.

Thanks,
