This is a new one for me...
My wife parked and turned off van after a 30 mile trip yesterday. I noticed a few minutes later the fan (psgr side) was running. Engine off, no key. Turned key to check gauges... temp OK, in middle. A "service engine" light on dash was on, but had been on a few days. Fan seemed to go faster, then slower, repeat. Finally, disconnected the + battery cable and it stopped. Reconnected it this AM, ran engine a little while, then turned it off. Has not reoccurred...
Sticker under hood says fan may come on at any time when ignition is ON... Never had it do this (to my knowledge) with it off though.
Any ideas what this is caused by? ('97 3.8 Gr Carvn ES)
THANKS!
