Turn Signal Issue

I just purchased a 2007 FLHTCU and took it on a trip. On the way home I noticed that the right turn signal wasn't working. Check the bulbs, they were fine, tried the four way flasher and all the lights worked, both the right turn signal, along with the left.
I called the shop and they were baffled. I ended up making an appointment for them to look at it but it will be three weeks before they can get it in. Anyone have any ideas on what I can check before then?

My bike just recently did this. I have an 08 Flhtpi. Everything was working fine and left for a ride today and I had no turn signals or break lights. I just rode it the other day and everything was fine. I checked the fuses and relays and everything seemed fine. I am also baffled.

Sounds like the TSM is in its death throws, I have seen them do this several times just one side not work but the 4 ways work just fine.

I'm new to this and still learning the lingo, what is a TSM?

Turn signal Module, if you have a HD security system then is it is the Turn Signal Security Module.

go to HD and have them plug it into the digitech.. its the only way to check the TSM if its going bad.. and if you have a handsfree sec system. RUN to HD to check, thats a tell tale its going bad, i just had to replace mine after a lengthy process of illimination
