Many of the stories here seem to be about rain or water getting in and freezing the latch, then freezing when the door is locked. We donít need to lock the doors at night and rarely do unless traveling. Will removing the SD tab help in other situations? If my door is not locked, but the latch freezes, does it matter if the SD tab is there or not?

The door handle can take 100s of pins
Pounds of force.

The DHC will break if either the self destruct button is stuck while the door is unlocked and the door handle is yanked OR the latch is frozen and you yank on the handle.

If the handle is free to lift (normal operation), you can pull as hard as you want it won't break. The problem is when the handle is restricted and then you pull, the hinge will be over stressed and increases the odds of breaking.

The DHC can break at any time just from fatigue failure, it happened to my left rear door a while back and it's still on my to-do list to take it out and repair it.

I think the self destruct button only engages when locked so it will help not break the DHC if not locked however, if you ever replace or repair a DHC, you should delete the self destruct tab it's ∞ more likely to cause a failure and serves no real purpose. (It's primary job is to allow the door to unlock while somebody is lifting the handle vs. the normal situation where you have to re-do the unlock command.

The door freeze situation can happen just from condensation it doesn't need rain just cold and humid then freezing temps.

So: symptoms; if the handle will lift bit no unlatch sounds, the handle is locked from the self destruct tab. Pulling harder will not help at all until the SD tab moves.

If the handle won't lift but the door is unlocked, then the latch is frozen. You can yank pretty firmly to try to break the ice free, but if 2-3 good tugs won't break it free, stop and open from inside.

Once open use hot air into the latch to deice and get the latch working.

Oh one other symptom/solution: if it's the weather seal that is frozen, the handle will pop up properly and you will hear/feel feel the latch mechanism work.

In this case you actually can pull quite hard on the door* and not break anything, but the proper way to unstick a frozen door seal is to PUSH on the door not pull. 5-8 firm pushes in on the door while holding the handle up (push pull push pull) will crack the ice off the weather seal by flexing it. I've done re his trick about four times this season.

Lubricant gets gummy when cold and will cause the self destruct button to keep handle locked when door is unlocked.

I have to walk back on use of wd-40 that's not a lubricant and when used as I show above it's intent is to displace water from the latch not the DHC.

Sadly I tried to treat wife's latch worth wd-40 and it still froze so either I missed or it wasn't effective. I'll do another test before I remove the actuator to fix like I did for passenger side.

Door Handle Carrier

It's the mechanism that connects the outer door handle to the door lock/actuators.

So I did the retro fix on wife's passenger door but only sprayed inside driver door. The next morning the driver door frozen: the latch not the DHC or door seal. I'm going to work on that door tomorrow and hope I can get my snake camera in to take a look before I take the door apart. Maybe with the snake wd-40 and looking with the camera I can avoid taking it apart.

FYI: I used my heat gun to activate (soften) the black goo that holds the vapor barrier and it worked very well.
