2016 Front turn signals won't flash

I just had some body work done to my 2016 mustang that required taking the front cap off. Now the front turn signals will not flash. They do come on as driving lights. The mirror and rear lights flash as they should. I was thinking a relay, but which one is it?

Thanks!

My front signals will not flash. They are on with the headlights on, but will not flash. Which relay controls the front?

Thanks!
