[Tech II]

I did not think of the after blow module aspect.....like I said before, the only thing I ever saw was the blower just would not shut off, and would kill the battery, and this was fixed by replacing the blower control module(in some rare cases, the blower motor had to be replaced also, due to spikes caused by the motor which would take out the new blower module)......however, like I said, I never saw one cycle the way you describe it....

If you are driving along, and use your defroster, which may or may not turn on the Compressor due to ambient temp, and then then say after 5-10 minutes, while driving, you turn the system off, does the blower stay off?

If it does, when you come to a stop, and then put it in park, with car running, is it still off?

Then, when you remove the key, is that when the blower comes on?

If yes, then this could have something to do with an after blow module setup(this is not the same thing as a blower control module).....I'm not sure on this year model, if they actually put in an afterblow module, OR if they could just "program" it into the system.....I know in the newer vehicles, they could program it into the control head/programmer.....in older cars, they had to add the afterblow module.....

The afterblow module was used to turn the blower motor on, when the car was shut off, in high humidity situations......there would be condensate left on the evaporator, and this would breed the growth of bacteria, which would create a sort of "fungus" smell when you would turn the blower on......with the blower motor running a few minutes after the vehicle was shut off, this would "dry out" the fins of the evaporator, preventing this growth....
