Have a 2014 Sierra K1500 conventional cab. I would like to have a rear slider window installed but seems like nobody will do it. heard comments about it having to do with the defroster in this window. I really don't care if the defroster is there or not; would just like to have a sliding rear window. Or is there something with the circuitry in the truck that would get screwed up by not having that window? Sure would appreciate any input on this. thanks.
