When Honda CR-V doors rust or seize, you always face the problem of a stuck actuator inside the door that won't let it open or close. This is a very common problem and has a simple fix. In understanding the basic operation of the door hinge on your CR-V, you can define the problem and learn how to fix it.
Inside your CR-V, there is a latch that hooks over the piece of metal on the other side of the door to keep it closed. This piece of metal is called the "striker". Now, behind the latch is a hinge which causes most of our problems. This hinge connects to the latch and also the door handle. When you pull the door handle, the hinge opens the latch and allows it to disengage from the striker for the door to open. If any of these variables are off, it will cause problems with the entire door latch assembly. Dependent on your problem, there are simple solutions which will help repair your CR-V's door latch.
If your door isn't closing because the striker is loose or out of place, adjust the striker. Your CR-V will have small hex bolts holding the striker into place that may have become loose. Align the striker with the hinge by closing the door until you can get a good eye to make sure the alignment is right, and then tighten the bolts to the striker. This will give your door a better feel and allow the latch to operate.
This is a slightly bigger problem. In this case, your door will not open or close due to the hinge not releasing the latch, so it sticks open or closed. Remove the door panel of your CR-V and you can locate the entire door latch assembly. Use a screwdriver to disconnect the hinge from the latch so the latch can close or, in the case of it being stuck close, spray WD-40 on the connection between the latch and the hinge to lubricate it and allow it to open.
In either case, use WD-40 to lubricate the hinge so that it has better communication with your latch. The lubrication will keep things from seizing and sticking in the future. Once the lubrication is done, re-attach the door panel and test the door handle to make sure it is fully operational.
