Heater control illumination

Post by Jon Sanderson »

I'll admit now that I'm no mechanic, but I did feel pretty proud when I correctly dismantled the heater control panel of my car and managed to get the blower working again (the little metal contact on the control disc had fallen out).

Only problem now is that my heater control illumination now doesn't work along with the illumination for the cigarette lighter.

Can anyone advise what I should check when I take it all apart again?

Cheers Tim, but they were working prior to me taking it apart - if it's just bulbs then that's an easy fix for me, but it seemed odd that they should all go at once?

Good point, do you have lamps in the speedo. Could be just a bad connection probably, I would take it apart again and check everything back together properly.

That happened to me, it was the panel light rheostat.

Ahh good point, Jon check its not come unattached, (its under the steering column) theres a neat hole not far from it you can stick your finger in and poke the rheostat out from inside the column casing.

I've had them ' go ' on me many times before and now when doing such a job , change them as a matter of course if they look to have dark glass and above all, check everthing works before reassembly

The lights in the dashboard binnacle still work, would it still be the rheostat in that case?

Nope. I would take it apart again and check the connector that powers the bulbs is pushed fully on.

The heater card connector plugs onto the back of the board near the top, be aware that the bulb holders there are slightly different to the ones in the binnacle, do not swap them over.

Yeh that!

The bulbs pull out of the holders in the heater control quite easily, normally by hand.
