Rear indicator light not working on Alfa 147
The passenger side (LHD model) rear indicator/yellow blinker light does not work. I had the whole cluster out yesterday afternoon and swapped the bulbs and holder with the driver's side to no avail (it worked on the driver's side).
I even got the multimeter out on it and although it read a voltage with the bulb out when the light should have been illuminated, it seemed different to the working driver's side. It's difficult to say as reading a changing voltage with a digital multimeter is difficult, but I guess the drivers side read +12, then +5 maybe, whereas the broken one read just +12, then 0v. I'm assuming there was no current as the bulb still didn't illuminate when it was connected and I didn't read any voltage. Additionally when I took the bulb out, the relay clicking increased in frequency (which I understood happens when the bulb is broke)... so it seems that the cabling between the control unit (?) and the cluster is intact.
I checked the fuses under the bonnet also to no avail, is there another fuse/relay or controller box under the dash for smaller circuitry like this?
Additionally it seems intermittent--sometimes it does work, but this is very rare. Could be a loose connection?
