Default 1990 LX Radiator Fan Problems

I finally got this running and now the rad fan will only come on once it warms up and I turn off the key. It will come on when it is running and will eventually over heat if I don't turn it off. I know what you are thinking, Relay, Fuse, or temp switch right? I have checked all of these. replaced all 4 switches with ones I know that work on another accord.

Can you guys think of anything else it could be? Thanks.

Mistake: It will not come on while the car is running and will eventually over heat if I don't turn it off.

the most often cause of this problem is temp switch 'A' at the T-stat housing.
Quick test is to put a jumper in the plug to see if the fans run with key on.
Beyond that you can check the fan controller and relays.

Thank you Sir, one more thing, sorry forgot to ask for the component location pic too. I tore a complete RA1 apart here to export all the parts and I did not see this module on the JDM model unless it was smaller than I expected to see and I may have completely missed it, maybe the JDM just does not use it, I was suprised.

Highjacking a thread for a similar issue is allowed. Thanks for the pics dude. I also can claim as others have, no JDM forum. You did answer my question 100%.

I owned one before, never had a need to look, parted one out for export, did not notice the module, I am picking one up today to resell so I will look for it again so thanks. I expect the wire colors to be different.
