I have a 2017 Express 2500 that has a bulb out in the front climate control panel. Does anyone know what size the twist type bulb that is so I can replace it? I have the bulb out but know one cane tell me the size. Thanks.

I found that a PC74 twist type bulb works if you just shave a small amount of the plastic off the side of the holder. Fit perfectly and cost me $1.50. The dealership wanted $200 to replace the whole unit.

I came up with a Phillips 912 but if it works use it.

sometimes the part number is printed right on the bulb.

Looks like a 192. Sometimes called a "wedge"

It’s a lot smaller then that and the bulb can’t be removed from the base.

then put something in the photo for scale.

This is what I used for the replacement.
