I replaced my side light bulb today as it wasn't working. Nice simple job, took the grill and the headlight out, made sure the light was working and put it all back together. Once I had gathered my tools and got everything sorted I pressed the button on the key to lock the doors and... nothing!
I tried a few times unsuccessfully and tried locking via the drivers door. Drivers door locked but the central locking didn't work at all. Now I am a little worried. Started the car to check that I hadn't shorted anything and the battery was still ok and it all started up fine. Checked the fuses under the dash and the fuse for locks was fine. Tried the door lock button inside the car and it worked perfectly.
After saying a few choice words I started unpacking my tools again - the sidelight hasn't been working since I got the car so obviously there is some kind of wiring fault that those £*$%&'s who sold the car to me were covering up. Then I had a last minute thought, before I started removing the headlight again I checked all of the doors.
The passenger door was slightly ajar
A waste of 10 minutes and stressing out all for nothing, I now have a full compliment of working lights and my central locking is perfect.
