why does my drivers window go down when I turn on the a/c? on 2000 Ford F-350 Super Duty

Happens only occasionally. Plug a trailer into it today and the window is down and I cannot get it to go up now. When I push the up botton the dash lights up, high beam indicator lights up, both turn indicators light on the dash.
