From what I can tell, the RHR P/N # is P68092000AC. High speed unit that will fit:
Will fit and work in:
2008 - 2013 Town & Country
2008 - 2013 Caravan
2009 - 2010 Journey
2009 - 2012 RAM 1500
2010 - 2012 RAM 2500/3500/4500
2007 - 2012 Nitro
2008 - 2013 Liberty
2007 - 2013 Wrangler (verify mounting style)
Not sure why mine is not working?? Could it be that my RER is low speed?? Andy, do you know of anyplace to have this unit looked at and repaired if necessary?
Thanks again for all your help!
