I'm on my second cruise control module. they both worked fine for about a week then they would only work some of the time, but after about two weeks they won't set at all. The fact that the second one that I just installed is doing the same thing leads me to believe that something outside the Module is causing the module to go bad. Anyone?

 

Relay (if there even is one lol. I dunno)? Fuse? Wiring?

If the module's are in working order before installing, you might want to consider it's something on your car that's messed up.
