Hi guys I have a 124 230e straight 4. Everything works but the vacuum pump has no power going to it. The pump works I know that. The fault evolved when I connected a jump lead to the aerial wiring in the boot in order to activate the pump when my battery had died from the alarm setting itself off. On this occasion the leads touched when I sent power through it. The pump activated opened all doors but look all four doors or I can't get in. I have to leave one rear door open. In order to get in. One of the door locks returns back in the hole even when opened from inside. Can anyone help please. Could you please dumb it down as much as possible as you'll lose me if you get technical
