Normally the temp guage needle doesn't get above the mid point, but lately it has risen above it and I have had to turn on the heater to bring it back down. I didn't find a blown fuse under to hood or near the steering wheel. I reseated most of the relays. But nothing changed. If I disconnect the cable to the temp switch near the bottom of the radiator, the fans come on with just the ignition turned on. If I disconnect the same cable near the battery, the fans comes on. And I verified with a meter that this section of the cable does not have a short, so it seems the circuit in the temp switch is closed and remains closed even when it gets too hot. Is there anything else I can check and should replacing that temp switch at the bottom of the radiator fix the problem? TIA.
