Excel Overheating

I have a '95 model Hyundai Excel Twin-Cam which is overheating. I have traced it to the cooling fans not switching on. It has air conditioning and the aux. Fan also will not switch on. I believe they operate separately from each other? All the fuses are intact and the wiring looks to be in good order. Problem is I can't find the thermo switch, I am presuming it is separate to the temperature gauge sensor.
Do you
have the same problem?

When U say "Falls" into neutral, does the shift lever move? Or do you just loose power? If U loose power check fluid level! If thats OK Tranny needs a rebuild.

The is a sensor that senses the coolant then sends it to a sending unit which in turn sends it to the ECM. Find the one and follow the wires to the other.

Should be right bellow the throttle body under the air intake hoses. Ill try to find you a diagram online. Should be hooked to one of the coolant lines.

Thanks for your help, blackop555. I found the problem. Would you believe ants! Yes, tiny ants! They had gotten into the fuse/relay box and into the relays - 3 of the relays didn't work. I pulled them apart and 2 had ants squashed between the coil contacts, the other one the offending matter fell out when I opened the relay cover. There were ants all through the fuse box. As soon as I had cleaned the relay contacts, they worked again! I HAVE seen this before, in the Northern Territory of Australia. The ants seem to have a liking for small electromagnetic fields.
