Hi, i am wondering if someone can offer me some advice on what may be wrong with our car. We have a 57 plate ford focus st 2.5. We have had it around 18 months and its done 25000 miles. Last week my partner said that the power assisted steering didnt seem to be working properly altho i hadnt noticed it at all. Tonight i have reversed the car into the drive, once id turned the engine of i realised i had left the window down however the car will now not start what so ever! I managed to get the window up without the engine running, however the window moved much slower then normal. My partner has been out since to try to get the car to start but still no joy. He has noticed that the electrics are playing up, if he trys to turn the window down the radio goes off, if he turns the radio up then the lights go off etc etc etc. The dash says ''engine system failure'' and ''acceleration decrease''

anyone any thoughts on what it could be? No idea if it is related but three nights ago someone tried to break into the car and managed to get the passanger window a few inchs but other then that there seems to be no apparent damage???

thanks in advance
