anyone know what size bulb goes in there?
Thanks for the help. I took another look at the service manual and see what you mean. I will do it when the weather moderates a little bit. But do you know the numbers for the bulbs that the factory used? I can't seem to get a definitive answer even through the FSM or on the blog. I'd like to be able to take it apart replace the bulbs and put it back together all in one day without having to order the bulbs and wait. ps I see your handle- I had a 1970 Cougar Eliminator with a 428CJ and a 1971 XR7 429 CJ back in my Ford days.You don't have to remove the upper dash panel. You DO have to remove the lower dash panel. It's the lower dash panel that includes the bezel that covers the climate control unit.
The #37(OEM?) is the dimmer of the two but lasts way longer than the #74 which runs hotter.
I do not know how to replace these bulbs without removing some dash trim and the CC. Have a look at the CC:

Most of these bulbs will last a lot longer if you just turn the dimmer down as low as you can.
