as in the title, we got down to -19 and i went out and the doors opened fine as i had waxed the seals but the door lock itself froze in the open position which wasn't so bad on the drivers side as i could hold that one and drive but i had opened the rear passenger door to get my snow brush out and the same thing, luckily by the time i had shovelled snow e.t.c the car had warmed up enough to release the rear door so it would close and lock but the drivers door took until i got to work to defrost enough, anyone know a quick fix for this? i geuss over the years the grease in the lock mechanism has broken down and let water mix in with it does anyone know of a product that i could sparay in there to give some protection, i was thinking silicon spray but the original problem will still be the grease that's in there any ideas on a quick way to clean this out, i'm not really interested in taking the pesky door panels off!.
