Water getting into the computer inside the firewall on 1994 Ford Ranger

windshield was taken out and reset and checked for any holes around that area

So i guess that didn't help? Get inside with a good flashlight, doors closed, and have someone spray water on first one place then another starting at pass. side cowl area and try to see the leak. Also check under hood around the firewall at the ecm harness connector. Spray and then wait it will take a few seconds for leak to appear. Dont just spray all over, start in one spot to help locate area of leak! May want to use a jug and pour water in one place. I hate trying to find leaks, pain in the a...neck!
