adam78 0 Posted September 24, 2007 Report Share Posted September 24, 2007 Hi all,I have a little problem my Aux water pump it wont stop running. When I park the car up at night and return the following morning it is still running!!!! I have had to take the 20 amp fuse out to stop this. Please can any one point me the right direction. Is it the relay? Is the relay the thing that the fuse goes into? Any ideas would be greatly welcomed.Adam Link to post Share on other sites

thegoth 5 Posted September 26, 2007 Report Share Posted September 26, 2007 Try disconnecting the plug from the yellow sensor in the thermostat housing. This contains the switch which controls the run on. If that stops it, you'll need a new sensor, if not my guess is it will be the fan control unit (under the header tank) which I think has to be replaced as one. Link to post Share on other sites

dagovernor 0 Posted September 26, 2007 Report Share Posted September 26, 2007 Is it your Aux water pump or all your electrics? one time my car went crazy and the wipers were working when i got up even though the keys were in my pocket. When i checked the Aux water pump was still going aswell. I had to take the battery out. Think it turned out to be a headlight bulb? Was strange might b worth checking.
