Condition
Some customers may comment on a door latch freezing due to ice accumulation in cold temperatures.
Cause
Water from a car wash or off the road may have entered the latch and frozen, causing the detent to move slowly.
GM Super Lube(R) has been found to be an ideal solution to resolve latch freezing.
Correction
1.
Verify that the striker properly engages the latch and that no obstructions are preventing the door from closing.
Important:
The latch and its backing plate have been removed on the above illustration to show the location for the lube.
