Hi..I have a 2004 crossfire..6 spd manual..around 40k miles..Car runs great..When I took it for inspection earlier this year they said they could not get back-up lights to work..but passed it anyway...When I got home they seemed to work ok..Then and now either intermittant or not at all...Is there a switch that needs adjusting or something else that I need to replace? Please advise....Wayne..
