Freezin's the Reason These Doors Are a Chore

Dear Car Talk:

I have a 2004 Hyundai Accent two-door. This is a winter question that I'd like to get fixed now, before it starts happening again. When the temperature drops below freezing for more than a week, I cannot open my doors from the outside. I have to crawl through my trunk and open the doors from the inside, or leave a window open so I can reach in and use the inside door handle. I cannot afford to get it fixed right now, but I am tired of crawling through my trunk.

What is wrong, and is it an expensive fix? Thank you. -- Kathy

That must be quite a show you're putting on for the neighbors every morning, Kathy. We'll look for you on YouTube.

There are lots of problems that can crop up inside old car doors. One possibility is that the latch mechanism itself is freezing. That's the easiest thing for you to fix yourself, Kathy.

You just open the door, and at the edge of the door (the edge that faces toward the back of the car when the door is closed), you'll see the latch mechanism. Start by spraying that with some WD-40 to clean it up and remove any dirt and moisture that you can. And then spray it with some lightweight lithium grease to lubricate it and repel moisture. You can get both of those things at any auto-parts store or department.

If that doesn't fix it, then the problem is inside the door. There are a bunch of rods and levers that connect the outside door handle to that latch mechanism. On old cars, they can get sloppy, rusty, bent or broken, so that the motion of your hand on the door handle is no longer getting transmitted to the latch. And if there's water in there, all that stuff can freeze, too.

The solution for that is to remove the inside door panel and expose the inner workings of the door. Once the inside of the door is exposed, you can have someone operate the handle, and you'll see what's moving easily and what's not. Then clean up everything you can, spray it with WD-40 (I would not use lithium grease on that stuff) and hope that keeps it from freezing.

The hardest part of that job is getting the inside door panel back on. It attaches with a bunch of clips, and you never end up with the same number you started with. And if you do leave the door panel off -- which you can -- you have to be careful not to get grease or WD-40 all over the left side of your clothes when you're driving.

But if it's a choice between elbowing in through the trunk and driving with a poorly attached inner-door panel for a while, I think I know which one I'd choose. Good luck, Kathy.
