87 Nissan Maxima, Cooling Fan Problems
Q: I have an Ď87 Nissan Maxima and I thought it is normal for the cooling fan to run after the car has stopped, but the fan just keeps on running. So the next day the battery was dead (from the fan is my guess). Could you tell me what might cause this? I looked on your FAQ and found out about fans that don't work, mine overworks..... J Lynn Wollam

A: Your Nissan is equipped with 2 cooling fans and 3 relays to operate these cooling fans. Itís likely that one of the relays is sticking on. On the left front of the vehicle near the battery is a bank of relays. The 3 cooling fan relays are side by side and have a blue dot in the top of the relay. The next time you shut your vehicle off and the cooling fan or fans are still running, unplug the relays and plug them back in one at a time until the fans stop. When the fans do stop youíve likely found the offending relay. If so the fix is a new relay.
