Illumination light out on air control module

[bradleyheathhays]

Hey there. '96 XJ here and my air control module in the dash has been dark about ever since I bought her ten years ago. I think 6-7 years ago the light for the unit came on just a couple of times sporadically but nothing ever since, which to me suggests a short somewhere maybe in the unit, dunno.

Any advice on how I should go about researching fixing this problem? First I guess i should install a new bulb just to make sure that's not it. Are the bulbs replaceable on these units?

thanks

Yes. Its one tiny bulb. Done remember the number tho. Pretty easy to change. Check the socket and wiring while you're in there. If any doubt, use a test light to check power and ground.

Thanks, all good advice.

I've been told too that I should change out the LEDs (?) in there as well. Didn't know there were any in there but if that's needed might as well get at em. Are they as easy to access as the bulb is?

Theres only a bulb in the HVAC control head.

I think they are talking about the mini bulbs (not true LED's) Switch illum for the rear window heater, rear wiper etc.

The plastic holder for these bulbs is junk, about half the time the little holding tabs break off. Most of mine are stuck in there with tiny drops of super glue.
