Set Clock on '96 Explorer

We got the windows working but we still haven't figured out how to set the clock on the radio! It's the factory one with the cassette deck and everything works but we can't set the clock; don't know how to!

check the owners manual, or just mess around with it till you figure it out

If you do not have an owners manual, try this link.

if it has a clock button and the seek buttons turn off the stereo, Hold the clock button and use the seek buttons to change it.
