I took my car to get washed at a hand carwash the other day, they didnt was under the bonnet but jetwashed the front of the car and bonnet. When I went to turn the car back on it cut out immediatly all the dashboard lights came on but wouldnt restart. The lights in the car all work and the radio, but I cannot turn the lights off now I have had to disconnect the battery. It also wont lock the central locking. When I put the key in the ignition now it clicks once but as I turn it again to try and turn the engine on it makes no noise and just turns all the way as it would when you start the car but doesnt turn over? Any idea what this could be please?
