Overheating warning light

[reidfussell]

I replaced a hose in which I to raise the cab. I pressure washed the underbody while I had it open. I did take off the fan selinoid but hooked it back up. Now the overheating warning light comes on after it heats up. I reraised the cab and checked all connections and all were good. Any ideas on what is the problem? I'm at a lose.

does the fan kick on if not unplug the connector and check the pin connections and tug some on wires to see if one broke off causing a open circuit.

Yes the fan is kicking on and runs faster with more rpms

Since the problem started after pressure washing my thoughts are water in the connections. I know you said you checked them but water is tricky. Make sure to blow out the connections with compressed air and then spray them with a good contact cleaner like "WD-40 Specialist Contact Cleaner Spray". You can also use a dielectric grease to help keep them dry (Permatex 22058 Dielectric Tune-Up Grease).

Ok thank-you. I will try that.
