Hi Everyone Just Wondering IF Anyone knows why my vr keeps blowing number 9 fuse everytime I use the central locking. It started doing this ages ago but my key stuffed up so I didnt use the central locking for ages but the other day I got a new key and everything worked fine central locking was working perfectly then today it locked then It didnt unlock and had blown the fuse it is a pain cause it is the same fuse that does the power windows and stereo so it was a hot quiet drive home yesterday. I replaced the fuse 5 times (whole Packet ) and it still keeps doing it I can lock the door manually from the drivers side and that is all anything related to using the central locking and it just blows the fuse It is a pian if anyone has any ideas please share.
All I can say is a process of elimination...Check and test all wires coming from the doors. check that none are pinched in the corner of doors. Just follow everything all the way to the BCM.
The drivers side door lock is very hard to lock and unlock could this be doing it. Also If I disconnect each power lock module in each door and test manually and try to eliminate which door is doing it will the other ones still work Or Do they run off the drivers door central locking unit
I think is runs parallel, not too sure. If I remember the rears you can dissconect. Yeah I would be checking the drivers first. Check all connections. Maybe give them a spray.
would the BCM be the switch/control device for the circuit? i know its not actually a switch but because it only blows a fuse when the central locking is activated it has to be after the switching part of the circuit... lol hopefully u know wot i mean. just a little bit of information to try help with the fault finding.
Okay I got the door trim off today the lock on the drivers side is really hard to lock and unlock but I can open with the key ok I have sprayed it and it is still really hard to move. the prob I have is I just dont understand why all of a suddden it would do this after working fine the day before. the doors lock when I press the button and the fuse goes straight away. The only thing I can think And I am not sure if this has anything to do with it and that is my power windows has started stuffing up and doesnt go all the way up about 20 cm from the top and I have to manually pull it up could this have anything to do with this thanks
The power windows usually stuffs up because the channel jams on the window as it goes up with also a drop in speed ...you can easily fix that by putting it down and putting the channel back in its right position as the window goes up. If you disconnect all the other door locks 2 rear and front left and concentrate on the drivers door to start with and it still does ....Id look at the wiring in the door...for the fuse to blow there has to be two much current being drawn.....2 ways ....short to body or negative somewhere in wiring etc or jammed mechanism(not sure if this would actually blow the fuse but it would draw more current) If previously everything worked with locking the car with the key...you would assume since all the other locks operated electically the problem must lie with the drivers door.....and the only difference when you use the button on the keyhead is that the right hand lockmotor is now being asked to unlock from the bcm on a brown/red wire by putting 12v on that wire. Put fuse back in and disconnect drivers lock motor try operating button on key and see if the fuse blows...if it does the wiring is shorted somewhere ..probably inside door....maybe the window mechanism as it is going up touches the wiring and shorts it out (long shot)?
central locking :rip:Okay I disconnected the drivers lock mechanism and the passenger lock mechanism and the fuse still blew. All that happened was the interior light turned on and off but indictators did on the first button press but then didnt work after that. When I press the button I can hear a clicking sound coming from around the fuse panel I take it this is just the signal trying to get through. I dont know whether to take it to an auto electrician all the door trims off so it might be easier to just just take it to an auto electrician before I put them back together. I just have a feeling it is something stupid and I dont want to waste money hey. I checked all the wiring in the door and everything seems to be fine any ideas ?
so uve tried it by disconnected each mechanism one by one? id disconnect each one and see if it helps, if u get really stuck and cant figure it out and feel u need to take it to an auto electrician then take all the door trims off take it to the auto electrician, get him to fix it and tell him to leave all the trims off... put them back on urself, this will mean he spends less time trying to find the fault... less time, less labour costs can anyone confirm whether the central locking is in series or parallel?
All I can think of is you've put fog lights in or something that is interfering with the C/L. Seems to me that if it all looks good the wiring and no shorting, then its either and another mod or appliance that is interfering with it. At the end of the day you've a big headache from all of this would be best just to get some elecy input from a professional. Could be the BCM in someway but it's pretty rare for it to cause a short in the system. Just another idea the BCM...
I will Prob Just Put it in to the auto electrician the Electric windows is stuffed as well it wount go all the way up stops about 20 cm from the top and the regulator keeps making a clunking sound when I keep trying to put it up. Thw indows is running on the guides fine so I just have to pull the windows up manually, when I want to wind it down I have to pull it 20 cm down ans then the window mechanism engages. As for the Locking system I will have another look today, as i got frustrated with it yesterday, and lost my patience I havent added any mods to it so I can definatley rule that one out. Just a question as well what are the wires that come off the lock barrel on the inside of the door. Thanks
