BCM,
you can't miss it. Just look along the line of the radiator to the left. Its a small pump mounted horizontal.
Make sure the engine is not at full running temperature as you don't want the radiator fan kicking in and grinding your wrist off!!! Start the engine then turn it off to open the switch to the pump. Now apply some pressure in various directions to the connector on the RHS of the pump. If its the same
problem as mine then the pump will come on when the connector is pushed in a certain direction. I bent the connector in the opposite directon and it was sorted when i connected it back up.
If its not this, try the pump fuse. Look in the owner's manual, I think there are several devices running off the same one. Take it out and have a look at the wire to see if its blown.
