Door cold lock

Hi Everybody

I have a suzuki sidekick 1994. In cold weather, my doors aren't closed more as if it would be cold. I am obliged to run my engine during 20 minutes for thawed out my doors and be able to leave. Would somebody have a solution to prevent my doors of cold?

p.s. It is not cold within the framework of the door but in the working procedure door

Thank you in advance

I would be tempted to take it apart and remove all traces of the old grease and grime. Then reapply a decent amount of white lithium grease to it. A fair amount of the parts inside are nylon and could be worn as well.
Enjoy.
