Ford Focus st170 Wing mirror/electric problem. UREGENT?

Recently had my drivers mirror smashed off whilst car was parked with alarm on. alarm went off and everytime i stopped it on the remote it kept going off. eventually it stopped. Temporarily taped the mirror on. when i came to drive the car, the light on the dash saying that there is a door open is lit up. all doors are shut. Central locking and alarm dont work, have to do manually with key in the doors. occasionally the left indicator flashes quicklyas if a bulb has gone, but then 5 or 10 mins later its back to normal. Not got a clue wots wrong. PLEASE HELP.
