On my 75 pickup, whenever it is less than 60ish degrees outside on a cold start, I get this crazy squeaking/rubbing noise. It gets louder as I speed up. If it's really cold it gets really loud. If it's a warm day, it doesn't happen. Doesn't happen at rest. Seems like once the cab is warmed up it goes away. It seems to be coming from the lower left windshield area. Since it only happens while driving I am a little stumped.
