Radiator Fan

[johnlampett]

Hello

I have 2.1 L Caravelle GL and the Radiator fan is staying on all the time

I had to pull the fuse before it flattened the battery .
I disconnected the Thermo switch and it still stayed on
I suspect the relay, anyone any ideas how to check it ?

Thanks

Sounds like a short somewhere, the fan (both speeds) is fed through the thermo switch by the same 12V feed wire (red/white in the 3 wire plug is the 12V feed) If you pulled the plug off the switch and it`s still running then it`s getting a feed from somewhere else. Had mine off the other day checking something else, and to get the fan to run I jumped the red/white wire to either of the other two to make it run. No feed, no fan.

Yes thanks still no luck
Been away for a few days thinking about it

Just checked the relay, I thought the contacts may be stuck
but looks in order .

not sure how to go from here

did you here a click from it when switched on.

there quite cheap

take a look at the wiring diagram and follow the Feed wiring route maybe you might spot a fault

The high-speed relay is fed from the same 12v supply (in the 3 wire plug at the thermo switch) as the normal speed on the fan, so unless it`s getting a feed from somewhere else, it doesn`t run at all

The high speed part of the thermoswitch supplies a relay that actually gets the fan on high speed. To me it sounds like the relay contacts have welded. The relay you need to check lives behind the dashboard so you'll need to pull that out before you get to the relay.

I think it is fixed, a loose connection on the fan
At least I pushed the connection home, it moved and the Fan does not stay on anymore.

I give it a run tomorrow to see if it will cut back in

Lesson learned - my camper bares no resembalance to the cct diagrams

Thanks for the support
