1999 Ford Expedition - Blinker dying

Me and my husband inherited a 1999 Ford Expedition and the blinker will intermittently stop working. It seems to be getting worse. What could be the problem?

The list is far too long for me to post here. 20 year old vehicle with unknown corrosion issues.

Best I can suggest is find a shop known for solving electrical issues.
