I am at wit's end. My 90 civic hatchback 1.5l F/I, no a/c has a cooling fan that won't run. Replaced the thermo switch - even though now I don't think it was bad, the fan motor is good and i did find a blown fuse. The fuse was replaced, has not blown again, but still no fan. I bypassed the thermo switch, still no fan. The dealer says there is a relay in that circuit, doesn't know where. Haynes shows a generic skematic with a relay in the circuit but the troubleshooting instructions don't mention it.My next step is to trace the wires from the thermo to the fan- what fun. any help appreciated.
