My Dodge Caravan is a 4 cyl. and the cooling does not seem to come on. I just had the head gasket replaced so I don't want to leave it running indefinatly just to see if the fan will eventually come on. I don't want to blow out the gasket again. In the Haynes manual it says to unplug the fan switch and if the fan comes on then the switch is bad. That doesn't seem logical to me. The Haynes manual is loaded with errors. I have replaced the switch and I did the test stated in the Haynes manual and the fan does come on when I unplugged the switch. Is this correct and does it mean I put a defective switch. Not sure what to do here. Any good insite would be a big help. Thanks.
unplug your temp. sensor its the 2 wire one the fan should come on when unplugged if so replace the sensor
