No need to douse everything; just get some wd-40 into the cable and work it like mad until it comes out the bottom.

If you don't get below zero where you live you have no concerns about the dla freezing up.

You can prevent DHC from breaking by using my awr-fix guide on the subject: 1 stainless zip tie will prevent the DHC from self destruct where it won't function. (it can break in a way that it's more difficult to operate but you can still get the door open).

Oh: and I've read that you can also swap dhc without removing the door panel by unclipping the cable through the same hole used to access the 4mm screw that holds the DHC into the car! (I will be trying this soon as one of my dhc is in "acting up" mode and I need to figure out what's up with it.
