DOOR MODULE WONT WORK WHEN TEMPERATURE IS BELLOW 50 ? Any sujestion?

I have a Envoy SLT 2002. The past winter, when outside temperature is bellow 50 the Driver Side door control module don't work at all. If i'm reset the batterie when the cart is re connected the door work but is a clink in the back for a few minutes and them gone.
Now... temperature is getting better and the door work perfect... windows work great, the seat heater work perfect and the memorie work too. Any one have any idea what it can be?
I check the door and looks like the door panel was remove... any possibility the plastic covert was remove and the door loos insolation?
I hope undestand my broke english and find somebody who can help me. Thank you
