My 90' 4runner was in a bad fire and I just recently had it up and running after three months. For some reason the fan comes on as soon as I turn the truck on. Is this normal, I mean is the ecu sending check signals since its been off for so long? Or have a crossed some wire along the way? Also having trouble with the power window/ doors. Will not work unless I have the back passenger door open! Any help would be appreciated. I would also like to thank everybody who has posted replies to some of my questions on this forum. Your advice has been very helpful through this rebuild. Thanks
