2006 Volkswagen – lubricating door parts

Dear Doctor: I have a 2006 Volkswagen with 33,000 miles on it.  I have had a problem with the driver’s side door. When the weather is very cold, I am unable to unlock the driver’s side door with the remote. All the other doors open without a problem. I have to go into the car from the passenger side, start it up and get it warm, then the door will open from the inside of the car but not the outside. After the car has warmed up, it’s fine. We have used de-icier and the dealer even put a new lock on the door, all to no avail. Do you have any advice? Opal

Dear Opal: When it comes to frozen doors in cold weather, lubrication usually takes care of the problem — not replacing parts. When lubricating any moving door parts and/or linkage never use regular petroleum oil. You need to use a synthetic oil or graphite only. You also need to lubricate all the rubber seals, including the trunk seal. Have the technician remove the door panel and lubricate all the moving door linkage. As for lubricating the door key cylinder, use only graphite and do not over-lubricate.
