The fan runs depending on the engine temperature........last weekend, very hot in Chicago, the fan was on when I stopped the car. The fan then switched off (car in garage, engine off) and then switched back on and ran for about 10 minutes before it finally stopped...........

The engine compartment purge fan rarely comes on. Mine has only come on twice -- and I live in 90 plus degree California! Here are the conditions the fan comes on at.

Switch-on conditions for engine compartment fan (this fan pulls air into the engine compartment). The engine compartment fan is switched on when the engine compartment temperature is > 176 degrees F or the coolant temperature is > 216 degrees F.

After-running of engine compartment fan

If the ignition is switched off and the engine compartment temperature is more than 140 degrees F, the DME control module remains in readiness for another 20 minutes. During this time, the engine compartment temperature is retrieved every 10 seconds. If the engine compartment temperature is > 185 degrees F , the engine compartment fan is switched on for 20 seconds. If the engine compartment temperature is still > 185 degrees F after this time, the fan remains on for a further 30 seconds.

I live in 100+ degf Houston, and I have never heard it come on during the past 4 months of ownership. And recently I didn't even bother to install the fan when I put the taco wing on. I figured I would get a fan fault light if it wanted to turn on, but it hasn't given me a light yet. I'll probably still put the fan in for completeness, but it seems like it's more for show....

Came home from work last week and put the car in the garage, shut the door. Went back to get something out of the car and heard the fan running. It went off after a while and came back on again. It was a particularly hot day in S. Florida, garage was sweltering. Seemed to act the way described in Loren's post.

I wondered how often the car "came alive" when I wasn't looking :D
