I am in the process of putting my car back together, but have found out my ventilation controller is not operating. The lights work, but the fan controller does not.
I am looking for a good quality controller if anyone has one that they want to let go of reasonably.
TIA

have you tried cleaning all of the contacts?

Also check the fan itself.

NOS one on ebay, not cheap. Make sure the plastic has not melted between tracks and run on to tracks.

I have this one. I have tested it with an ohmmeter and all three fan speeds, as well as the illumination light contacts, work well. As you can see, the contacts need to be cleaned or they don't make a good electrical path and tend to melt the plastic substrate. Yours might need this treatment as well.
