Any more suggestions on the solution to this? :) Sounds similar to a problem I had last weekend. Sitting in a queue of traffic on a hill, in heavy rain, wipers on intermittent, they suddenly went crazy and hurtled across the screen, still intermittently. Switching off at the stalk switch didnt make any difference, only turning off the ignition stopped them going. Later, on turning on ignition again they behaved ok. Could this be the control module getting wet? :)
