Title: Central locking fuse randomly blows
Post by: addy on 11 July 2018, 09:51:45
Here's a strange one for everyone. Maybe someone might be able to answer it for me? The Central locking fuse on the wifes 1995 CD Estate keeps blowing randomly, it works for a couple of days then just blows the fuse. The central locking doesn't seem stiff locking and unlocking no problem. A while ago it had the lazy locking symptom on the drivers door, but after spraying the locks and motor with lubricant (it was the none sticky type), it worked OK and still seems to be, it just keeps blowing the fuse, random now. My thought is that even though the locking motor is working, it is on its way out so causing a overload. does this sound reasonable? Other people have suggested maybe the heating element is shorting, as it is on the same fuse. The heated seats haven't been on due to the hot weather, so would the fuse still blow if they are not on? What wires to the drivers and passenger seat do I have to disconnect to see if it stops blowing the fuse? The lights flash when pressing the fob, just doesn't lock, check fuse and it's blown. It has the correct rated fuse.

All help is appreciated.

Is it the IR or RF locking?

I had that on mine it was the boot wire in between the the boot and the shell. might be same on yours but not rule out the door rubbers. the wires were splitting and every now and then would ark and blow the fuse. then be fine again until the lock stopped completely.

Hi Chazza12
Was your break inside the actual loom part under the rubber cover going from the boot lid, to inside the car? If it was how did you manage to track it down?

TheBoy, sorry not sure. It is a 1995 model, where the door lock fob is seperate to the key, with 2 buttons if that is of any help?

If you have to aim fob at dome in roof at max 1-2 meters away its ir. If you can just aim in the cars direction from 10-15 m away its rf:)

I took the roof lining out at that end and the side panels in boot sides and removed the boot covers. And used a meter to test the wires. By hooking them up at each end. Took out old wires when found the damaged ones just cut them off and used a bendy strong wire to put new ones in pass side has heater window and a few wires radio etc drivers side has locking and back feed and break light on mine. 3 wire were spilt on mine think it was one return earth and the heater and locking power feed. Would recommend to stick the wires back to the lining when finished as makes some funny sounds on the roof if not.
