I own a 1993 dakota that has a blown bulb in the heater/ac dash unit. All the rest of my dash lights work. I have pulled the unit out of the dash, but I can't find where the light socket/bulb is located. Any ideas would be helpful. Also my 4wd light stays on all the time. Adjustment of linkage? The transfer case does pop out of low range when you let off of the gas in gear.

 

The FAQ has the service manual to download. That will be your best option for a light bulb location.
