daytime headlight sensor
is there a way to cancel the auto headlight sensor out completely, so that it is a manual function ie.pull headlight switch only when I want the lights on.Now dont get me wrong the daytime lights that are on all the time are ok. but the headlights popping up in my garage or under a brigde or when the sun goes behind a cloud is alittle to much! 
When itook it to GM the tech tried to cancel it out but couldnt. Ihave tried the parking brake handleup a little,Ihave tried to cover the sensor on the dash no go.if anyone out here knows if theres a fuse or something else I greatly appreciated. 
It is Canadian car 2002 roadser that Ihave had no other problems with,but ihave already replaced one headlight motor,cause of defect probobly unessesary over use,so you have it.Signed joni eh!
