Overnight the power windows and locks quit working. Later in the day the fuel gauge, heater, radio antenna, and dashboard started to act up as well. But it starts and runs fine. Cleaned the grounds I could find. Checked connectors on the ecm. All looks fine. Thinking the solenoid or ecm. Am I close

Not even close. Check battery for condition including load test most places do for free. Have a pro check to see if your dash is bad as this h appens a lot.

F door locks and windows aren't working and power goes to switch see If power goes to window motor if not check for a broken wires between door and jamb. That happens on older cars. Why does everyone jump to a bad ecm whe it has nothing to do with window operation? Also check relays at base of a pillar for locking and unlocking. If power does go to window motor then slam door hard as you can without breaking window. If it works motor is bad.
