92 Civic radiator fan doesn't work

My 92 Civic runs hot because the fan doesn't work. I jump wire the radiator
fan off the condenser fan plug and the radiator fan works; so it's not the
fan. What else could stop the radiator fan from working? Is there a sensor
for this? If so, where is it located and how do I check it?

Thanks,
Al

 

If your car has no fan switch relay (like the '91s), go here:

Your switch is bad. Easy replacement, and cheap. The one in the pic has had
its connectors repaired on account of a ham-fisted oil change by me eleven
years ago.

If it *does* have a fan switch relay, try here:
