I recenlty noticed that my 90 accords cooling fan was running hours
after I turned the engine off, and kept running until the battery was
dead. I recharged the battery and started unpluging sensors while the
fan was running to locate the problem. When that didnt work I
unplugged the cooling fan relay located in the fuse box under the hood.
That finally shut the fan off. I then noticed that I could here some
clicking while I was replacing it. Nothing unusal, but it continued
clicking after it was pluged in (and the fan continued to run). I
unpluged the relay and called it a day. The next morning I pluged the
relay back in and the clicking noise was gone, and the fan wasnt
running. I thought the problem fixed itsefl until I drove it to work
and the damn thing started overheating. Now the fan wont come on at
all. I replaced the relay, and that didnt work (no clicking either).
I dont think there is any power going to the relay, but I dont know how
to check for that. I was told that it could be a bad cooling fan
switch that screws into the radiator. I was going to replace that next
but I want to get some professional feedback before I start replacing
parts. Any advice would be much apreciated.
