Spade connector popped out -Help Please

Do your wipers work?

If you're confident that it is part of the wiper harness, get your multi meter out, turn on ignition, turn on wiper switch and check the bulkhead for power.

To be sure you have the correct spot, turn the wiper switch off and check the same hole where you found power while it was on.

There appears to be an empty hole in the bottom right connector.
