Ford Repair: Does this sound like a computer problem to you?, power steering rack, mom and dad

Question
Ok, so our 1998 Windstar has been running ok and has about 130k+ miles
on it. We've replaced the transmission, battery, O2 sensors, power steering
rack, and a bunch of other minor junk on it. Now, this summer, our alternator
went out. So, we replaced it. After the new one was in place, the car ran
great, but we lost our electric windows. Today we went to my Mom and Dad's,
and my Dad had looked at the car manual, and thought he had an idea on
how to fix it. He pulled open the wiring panel on the driver side door, and
used a continuity device to make sure everything was connected and had
power. Everything checked out ok. Next, he and my husband checked all the
relay switches on the driver side area to make sure there were all in and ok.
They were. Next, they checked all of the fuses under the hood. Again,
everything seemed fine. They put everything back together and figured that
was it, and we'd have to go without windows. Fair enough. However, when we
were going to leave, the car didn't start. It wouldn't even turn over. My Dad
hooked his code reading device to it, and it could not even pick up a link with
the vehicle. They rechecked all of the fuses and switches to make sure
everything was properly connected. My Dad also decided to disconnect the
battery to see if he could even reset the computer. After everything was
reconnected, it still wouldn't start. So first, we went from no windows, to now
having no car. We're a one car family. It's stressful. We don't really have the
funds for a new vehicle, but if this is an expensive prob, we might have to
find a way. What do you think? Computer? Electrical? Wiring? Both? Any help
is greatly appreciated. Thank you.

Answer
no it doesn't sound like a computer problem
first did the battery run down while windows were being checked-
connections at the battery and on the block tight and clean
disconnecting the battery only helps if you have a bad connection and reconnecting it you may get a better connection-if there were any codes stored the they may have been compromised when battery was disconnected
could be a bad ignition switch tap on steering column while wiggling or rocking key back and forth trying to start truck.
does any lights come on dash-headlamps or wipers and blower motor? while key is on.
first i would be looking for connections and or bad battery
let me know.
