2004 C320 turn signals stuck on
 

Hello,

Been a long time since I have posted here. I have a 2004 C320 that has its front turn signals stuck on (even with the car off and the key out). Until now I have just left them unscrewed and prayed I didn't get pulled over. I finally have some money to fix it so I am.

I have found out I have to replace the SAM module and bit the bullet and bought the part from the dealer to avoid having to reprogram it ($315). Are there any gotchas or bugaboos I need to look out for?

I found a video any other advice? https://www.youtube.com/watch?v=HWYOFoanOKQ


Thanks in advance
