Heater / A/C / Panel Lamp

[Mikey1989]

If I am reading this correctly, pg 61 of the '88 electrical manual shows an illumination circuit for the heater controls.

 

Sure would be nice if my '89 had a light on the heater controls. But I'll be darned if I can see where a bulb would even go. Maybe this was only in trims that had the A/C - mine has no A/C.

All Jeeps have it. The lamp is twisted into place on the right side behind the panel. Careful, the socket is fragile. It should be a small “74” bulb I think. Same bulb that goes into the info center on the cluster. I do not remember which way it comes out but I think it’s regular lefty loosey

In one of those twilight zone events last night the heater panel was lit!

That did not happen by accident so likley to not stay so. Must have been something I poked earlier in the day when I was working on the radio. Still have the instrument panel trim off so I'm going to take a look and see if I can figure out what happened to make it start working. The glove box light is missing presumably the same bulb.

That’s a different bulb. Bit bigger and same bulb as the bulbs that light up the cluster gauges.

I was having problems with my radio display light going out.  The radio would play and keep memory, so I knew it was getting power.

 

I did Cruiser's instrument panel ground upgrade and that fixed the radio display and the other lights improve a lot.
