thanks for the help, and sorry for the delay in replying. I asked the question when I was 1000 miles away from my sons car, now I am home.
OK, the relay you pointed out is the cooling fan relay, but not the correct one in my case. The fan that runs 24/7 is the smaller fan next to the cooling fan.
I am not sure I got it right when I explained the situation originally. 2 fans, the bigger one(LHS looking from the front) works normally, seems to come on only when the air conditioner is turned on, the slightly smaller fan (RHS)supposed to come on when the car gets hot, and also when the air is turned on, that is the one one running all the time. I found the relay for that, it is one of two located at the front of the engine bay. So I disconnected that relay, reconnected the fan at the fan, and it is definitely the right relay, as the fan stayed off. Reconnected the relay, and it all works normally now, fan comes on when air on, comes on when temperature reaches a certain point, and goes off when engine cools down or ignition is shut down.
So, obviously whatever was causing the problem has gone away, but I fully expect it to return. So I have purchased a new thermo switch for the bottom of the radiator, but can't find any details on the relay.
Can you give me a part number for the relay, or should I just buy one from Honda?
Many many thanks again for your help.
