Radiator Fan Not Coming On

[Paulk]

Can anyone help out there.
I have a 1981 Beta Coupe 2000. The radiator overheats as the fan doesn't come on when hot.
I have replaced the sensor and tested the motor and everything seems fine that I can see.
The only thing that I can see that does not look right is there is no relay under the fan fuses in the fuse box.
Should all relay bays be used under the 16 fuses. The two on the far right of mine are empty.
Not sure if this is related to the problem.?
If so, where could I get replacement relays from.?

There should definitely be a relay for the radiator fan. On the facelift fuse box there is a picture on the clear cover where it fits. They are fairly common relays. I'd try ebay first.

Thanks Neil.

Hi Can anybody send me a picture of the last 2 relays in the fuse / relay tray on the right hand side, I need to know the configuration of the pins. !?
Theres a diagram on the front of the relay.
cheers Paul.

Update-
I have definitely got a relay in the fan housing. (Switched one from one of the other bays as they seem the same)
I connected the wires to the heater switch together, so bypassing the need to heat the water or the switch, and all I get is a click from the relay.!

Unless there is any other components in the equation I have to assume there is a problem with the actual wiring from the relay / fuse back to the fan .!?

Always worth checking the earth from the fan as well. If the earth isn't connected (probably to the earth rose under the passenger side headlight unit), then the fan won't spin. I've been working on mine today, but didn't see your message until now. I'll take a look at my setup when I go back over to it on Saturday, and see if I can see anything else worth checking. Mine's an 81, so probably the same as yours.

Thanks, - that's another thing my earth rose is falling to bits.!

Sussed it, after testing all the components and buying a new switch i traced it to a dodgy wire connection. !!
Thanks for your help,
