Some might remember I had a problem with my Peugeot 306 1998/S speedo sticking, only increasing and not returning to 0 following cold weather. Well, I visited the dealers yesterday to ask about the price of a new instrument cluster. I was politely told £365 inc VAT, pay up front, and non-returnable as it's an electrical item. They said it certainly sounded like the instruments, especially as I said the digital odometer was increasing correctly (so speed sensor is okay).
Well, after a little work, I removed both the 2 small geared motors (stepper motors?) which work the speedo and rev counter and swapped them over.
Result? Rev counter now sticks, doesn't return to 0 and increases each time you rev the engine. Speedo now works perfectly.
I then removed the new rev counter (ex. speedo) dial and plan to dismantle it to see if there's some problem in the gearing or something. No idea if I can find a replacement for it - but no point keeping it in there whilst it's not working.
Only problem is now without the motor + dial there the backlights shine through at night - I'll just stick something over the hole for now.
Any suggestions as to where I might be able to source a replacement motor? No idea of the manufacturer, pin outs, or where to start. My only real chance is finding another broken/cheap speedo and remove the motor from that (probably easier than finding the exact model spec instrument cluster). Just need a working motor - not any of the rest of the instruments.
Some pictures of what I did, including the part I want to find a replacement for:
