Wipers come on when using turn signal

This was replaced when flasher light module was changed. this all happened after changing the headlight on the left front cause high beam was out. Everything worked ok for 4 days after the switch and bulb and light module changed, and now my daughter says this turn signal/ wiper issue
 
If you are in a position to check, go over all of the contacts and grounds that were touched during the switch/bulb/light module change.

Seconding this, especially if you replaced the MFS already. My wiper/turn signal issue was the loose common ground behind the driver-side headlamp assembly. The screw had wiggled it's way out.

My MFS issues were quite a bit more fun before I figured that one out... Headlights would go out permanently if you used turn signals or fog lights while the switch was hot
