Honda CR-V Tailgate Light on Dash May Filcker
Honda CR-V Problem

I had this same problem after a long trip. The fix was very simple actually. I noticed the screw on the rear latch had worked it's way loose. I fixed it with a simple Phillips Head screw driver and just tightened it up.

Rear hatch light flickers when driving. Cannot lock doors with key fob due to "mistaken" rear hatch window open. Must use key to lock doors because of this problem

We bought the car used and everything worked fine. Just yesterday the tail "idiot" light would not go off. We discovered that it would go off if the latch was pushed in all the way. Then we noticed that the latch was sticky...like something had been taped to it. So we decided to try attaching little sponge-pads to it. (Bought at any department store or hardware store. We used the ones that are about the same circumference as a pencil eraser and about 1/8 of an inch thickness.) It took three of the little pads piled on each other to get the light to go off. I put a fourth on for good measure. But problem solved. None of the screws in the area of the latch were loose at all. I'm keeping a stash of these little pads in the door of the CR-V for future use as I expect they will fall off or get too squished eventually.
same problem, dashboard red light on indicating rear hatchback door open...can't use remote lock button when light is on (have to insert key into lock to lock/unlock doors). Tried a little WD-40 to latch and hinge and will tighten all screws in latch area and hope for the best. Even though the light is on that it's open, after manually locking the car, the back door is locked. **** UPDATE ****IT WORKED!!!! I tighten all the screws around the silver U shaped latch, and even though only one screw tighten only a half a turn it must have been enough to realign the sensor that the hatch was closed because the light is OFF! Thanks to "msbellamy" (report #6 of this page) for your sound advise and for sharing it, so appreciate it. I'm sure his/her advise saved me a minimum of several hundred dollars! Also thank you internet for all the advise over the years, I'm sure it's saved me thousands!

Same problem with blinking light, happens more often uphill. Pressing the window doesn't make it blink, but if you press it down towards the ground, then it will light on. Will try to fasten the screws tomorrow.

There are two check-switches that the car reads. One in the flip-up window, and another on the left side of the side-opening door. Don't assume it's one and not the other. I did and spent an hour messing with the window switch before realizing that it was the door switch instead.
The door switch is a sliding black piece that contacts the door when it closes. It's on the left side of the rear of the car. That is where the phillips head screw is that others have mentioned.
