OK, you need some soldering to do internally inside the radio. This video is from a 2000 Ford Explorer which I believe has the same radio (MACH RDS) you have. The way it is bolted on your Escape is a little different from the video. But you have to find it out how to take off the radio.
If you don't want to fix the radio, your better of buying a used one either on eBay or a junk yard. Or if you a want to upgrade, go for the aftermarket ones. Good Luck.
Thanks. The radio works fine whether the display is on or not. I'd like for the clock to display. The clock and radio display are either both on or both off (when they should be on). The problem is with something that powers both.
