Ok so there is a snow storm outside and i was driving to a friend's place and decided to play in a parking lot on the way. When i tried to engage the 4x4 it wont work. I have a 93 XLT with push button transfer case and automatic locking hubs. I Just used the 4x4 successfully a few days ago, so I cant figure out why it wont engage now. I let my car warm up for about 5-10 mins before i drove it. I tried engaging 4x4 in every gear and still nothing. When I push the 4x4 button, i noticed my instrument panel lighting dims slightly for a scond, and the volt meter dips. I really need 4x4 to get around in this weather so HEEEELP PLEASE!!!
