a/c control backlighting

[68oldshotrod]

1999 T4R Limited. A/C control backlighting not working when lights are on. Is there a bulb that can be replaced or does the unit have to be replaced?

It's a bulb. If it's the buttons then the backlighting uses a neowedge A and if it's the LCD screen then the backlighting is a neowedge B.

Where can I find thse bulbs?

I have used autolumination.com on a couple of occasions. I would recommend replacing them in pairs, i.e. if one neowedge B needs to be replaced I would replace them both so that there is no difference in the lighting.

Same P/N bulb for 4th gens?
(Just asking before I tear apart my dash for the thousandth time)
I have no lights on the left 2 of my climate control knobbie things. I should probably check a fuse - but I would think that all 3 would be out if were a fuse.

I just ordered 3 replacement bulbs for my temp up-down thingy and my fan speed control backlighting. I got one extra just in case. I should have the bulbs on wed. I will post the P/N when I get them.
