96 Blazer driver side door buzzer

My driver side door open buzzer comes on, only when its cold outside, when the door is shut, and when i turn right. The buzzer goes off when i pull on the door handle, but as soon as i let go of the handle, the buzzer comes back on. It will eventually stay off when the cabin warms up. Does anyone know if there is a switch in the door that maybe getting stuck from the cold? Any tips would be appreciated.
