workhorse 4 way flasher module

Anybody having problems with the 4 way flashers not working? I think I have isolated the problem to the module. Anyone had one replaced? Anyone have the workhorse part number? Source for the part? Cost of the Part? I have a 2002 w-22 under a Southwind. Thanks for anny info.

You might still be under warrenty. 3 years or 36000 miles. If so WCC will replace the module.
