Lights on Heater Control Panel

[PaulQ]

This is a picture of the PCB in the heater panel:

and this is the whole back

There are 2 holes for capless bulbs. Are there any more lights in the unit? (e.g. under the power input.) I ask as I replaced the bulb nearer the heater speed switch and it's still not lighting up. It could have blown again, but there seems to be no reason for this to be the case.

No, just the two bulbs you see. That is all. It has blown again. Or, maybe, the bulb is not seated properly and losing a contact

Thanks. I'll have another go. Given how simple the contacts are, it's hard to see why it should blow but the last one had. Perhaps the contacts in the cap are touching: I'll have to wear my glasses this time.

I forgot about this until I found a capless bulb and its mounting rolling about in the footwell... I put it back and all is OK. Another non-event on a reliable Puma.
