I've got a 1991 Integra LS with a B18A (I think that's all the LS came with). She's a champ, but when you turn it off, the radiator fan keeps blowing. I disconnected the motor for now, but I'm curious if it's the switch or the fuse or the relay or what? Any help would be appreciated.

TIA, fellas.

 

It can't be the fuse. A blown fuse would prevent it from running AT ALL.

Unplug the fan switch. If it keeps running, then you know it's NOT the fan switch's fault. Then you just have to figure out between a bad relay vs. shorted wiring.

I don't have a '91... I don't know it it's supposed to be able to keep running after you turn off, when it's really hot. But I know it isn't summertime in Wooster these days.

 

I believe as cars get older they have problems with the Fan Relay sticking.. That's jus what I heard.. Never replaced it myself..
