Welcome. I am also pretty new to this forum stuff but getting tons of info and really enjoying it.
You might want to post more specific chassis info to get more specific feedback ( ford, Chevy, etc)
Try the coach manufacturer for manuals that you can download and same for the chassis.
I amI sure with enough info to work with someone on the site will know exactly how to fix. Maybe a little more detail about problem. Any clicking, do other lights work? Definatley get flasher checked out
