Does anyone know how the heater instrument light is removed? I know that it's from behind, but it in there pretty snug and I don't want to just pull on it or twist it and end up snapping something off.
I think the best way to get at it will be to remove the instrument cluster faceplate, then remove the clock or blankoff plate (comes out from the front of the dash) and go in thru the clock opening. That way you can see down into the HVAC control and get a bit better view of what you're doing.
This the floodlight above the HVAC head, right? Bulb replacement should be remove the floodlight lens and replace the bulb if that's all you need to do.

There are two light bulbs in the lower part part of the dash just over the heater control levers (same as over the wiper switch on the other side of the steering wheel). When you remove the phillips head screw and green acrylic lens, there is a small metal diffuser that is part of the lower dash, so the bulbs aren't accessible by just removing the acrylic lens. I can reach the bulbs with my fingers from under the dash, but they would not come out by pulling them straight out or twisting them, as you would for the rest of the dash light bulb sockets.
I'll see if I can find a reference - I've replaced many bulbs. I "think" the bulb(s) you're after are 161 bulbs. I'll have a look at the PIM to find a number to cross reference but I'm rather certain they're of the 161 type.
So far, no luck. I think there exists a chart in either the CSM or the PIM which lists the bulbs/lamps and locations? Can't recall. I was hoping the page which lists the flood light filter would list the bulb/lamp - no such luck, sorry.
Sorry can't provide more help. I just can't remember exactly which bulb it is. Even the chart Joe listed in this (below) URL link doesn't provide the exact position for your situation (that I could find). It's an inquiry you made yourself some time ago. Good Luck.
They are in plastic housings that need a quarter turn counter clockwise to remove (counter clockwise if you're laying under the dash looking at the back of the bulb). Easiest to get to by pulling the clock (or tach).
The plastic is probably extremely brittle and will break. That's more or less OK - it'll still hold the bulb but might rattle. Replacement housings are surprisingly hard to find. You can get an entire accessory light harness with the right housings, or try a generic "twist lock 168 bulb socket". You need the ones with wires - not the ones that have wipers that go onto a circuit board. I haven't verified that the generic ones actually fit though.
Thanks for this info. Kind of what I figured, but did want to just snap them off. I've had the car since 1978, so I guess I can't complain that I have a bulb out.
