Near side fan

[drivingfroggy]

Sorry about the repeat topic. Does anyone know how the nearside radiator fan is controlled? My offside fan works OK, and both fans work on the default setting (plug disconnected). I swapped around the relays and the offside fan works correctly with both relays. The car doesn't have air con, so I have ruled out a trinary switch, unless of course TVR fitted trinary switches to all cars regardless of air con or not. Any help mucho appreciated.

Have you checked the fuses, no 1 and 15 !!

Fuses!? D'oh! I haven't checked. but I will tomorrow, let's hope it's something as simple as that.

It was the problem on mine when I had the same symptoms. Take a look at this post as there are a few other suggestions;

Haven't checked the linky, but, the other 'bad actor' is the multi-plug connector on the fans - right at the front of the car.

Renowned for the connectors to corrode and stop the fan working.

Well I've checked the fuses, swapped the relays and cleaned any corrosion off the plugs.The nearside fan still won't run. The only thing left in the system is the sensor. Is this a two stage affair? or does an ecu tell the car what to do. Surely a cooling fan system shouldn't be this complicated?

Sounds like the ECU may not be doing it's stuff. Have you got the lead and software to see whether it thinks they are on or not?

The o/s fan comes on first, then the n/s as well when it gets hotter. Are you waiting long enough for it to do this? Someone else will confirm the temps they come on it, but I think it's 92 and 96 respectively.

The offside fan comes on at 96 no problem. I've ordered a new sensor, I'll stick that in and hope for the best

Finally got both fans working! Fitted the new sensor, still only one fan working. Spliced in a new plug to go onto the sensor, and hey presto! Turns out one of the wires had corroded and snapped inside the plug right at the spade connector where it couldn't be seen. For those that are interested the plug is available on ebay......
