I sqirted a considerable amount of freeze spray into the BEM today when the car was hot enough to fault. Fired 1st go.
Drove the car for 10mins and then found power windows wouldn't work. I then heard a click-click-click sound; Reaching down, I could feel that something inside the BEM was switching (like a solenoid) causing the sound. 1st click=windows dead, 2nd click=windows worked, 3rd click windows dead etc...
Taking advantage of this opportunity, I stopped the car and started it, fired 1st go. Stopped the car and waited for the next click... tried to start again, wouldn't fire. But wait, this is the best bit... whilst cranking and cranking and cranking, the 3rd click occured and the engine sprung to life! Sounds pretty conclusive to me :):):):):)
Additionally, the Smartlock lite was constantly illuminated as I drove the car home.
I'll get a new BEM and see how that goes.
