Drive Train. Your Ford dealer lied to you. Call the bulbs on the instrument cluster are replaceable. You do not need to buy anything except some bulbs. Here is a backside pic of your cluster. The arrows show replaceable bulbs for our dash.

I would bet that your headlight switch is bad at the rheostat for the light switch. This is common with most H/l switches in general. Sometimes you can move them slowly and they will contact and work, but usually when bad, its replacement time.

Click on my "akdoggie" tag and you can see the picture that I couldn't show you here. Weird but its in my Service Manual. you'll see the pics. Good luck

 

Never never never trust a dealer.... I don't know if being a pathological liar is a requirement to be employed at these places, or if they just do a lousy job training their techs and service writers... But they rarely seem to do anything right. Last time I went to one they said my front brake pads were worn down past specs (I only went because I got 2 years of free oil changes on my Town Car as a perk of buying from them) so I checked when I got home... They were practically new......
