Need some help, left a 2000 deposit on a 2000 ford explorer. Nice vechile, but concerned that it is not what it seems. On the dash the guy tells me that the cigarette lighter is missing.. This vechile is an AWD and yet there is no button to switch from 2 wheel to AWD. should there be a button or is it just AWD all the time and I am worried about nothing. This is a 2000 ford explorer XLT Please help
