Hi Bruce, welcome to

Please check voltage between hot & neutral (white) then between hit & ground (green or bare) & let me know what you find. Thank you

Between hot and neutral is 106v, between hot and ground is 123V.

Thank you, this is an indication of a loose connection on the neutral.. the bad connection could be in that switch box in any box between there and the panel or in the panel. I would start in that box reach with the neutral connection and put a good wire nut on it then keep working back from there until you get good voltage.

Unfortunately it's just a time-consuming process search for the bad connection until you find it.

I am here to work with you until it is resolved so let me know when you have questions thank you

If your outlets are wired using the back-wire, push-in connections instead of the screw terminals, one of these connections is likely to be the culprit.
