Its been said that the GEM module doesnt like water, and common windshield leaks can provide a path to the GEM. No electronics like water. If this 02 has a GEM module(?) look for water leaking around it. Im not well versed with this problem only learned about it here.
Remove and clean all the battery cables down to the starter. Do this first to insure everything has a chance at a good connection from the battery & alternator to ground. Then start digging. Look for critter chewed wires especially if this truck sits for long periods. Might have to take it somewhere and have them plug into the truck and look for stored and present trouble codes. Trace the power window and radio circuits and look for a bad or lose connection. Typically the cowl to door harness can become fatigued from repeated door open/close cycles and the wires simply break. You could have two unrelated problems too? If you're having a shop trouble shoot this its time consuming and costly to do. Start with the simple stuff you can do first. Report back on the fix.
