Hey Guys!

I purchased a 2009 c30 about a month ago.
It was cold yesterday and today, about 5 deg F today, and the drivers door would not stay shut! Yesterday it worked after a few min, but today it was much colder, so I found a different way to get to work.

Does this meant that the lock mechanism needs to be replaced? Door lock actuator? Is this a hard job to diy?

Thanks!

 

Thanks for the reply.

After it warmed up a bit, ~20 deg F, the door lock started working again. I sprayed the locking mechanism with some wd40 to drive off any water and the door has been working properly (even in -5 deg F, I am so ready for this winter to be over)!

If it malfunctions again I will replace the actuator.
