my car says the right rear door is open but it isn't.
What is your question?
Sometimes this makes the overhead lights/dome lights come on by themselves at random times, even when I'm driving. Mostly, it seems, when I come to a stop at light or stop sign. Also, and this is the main problem....I can't use my security system to lock my car. I can lock it down, but after a half hour or so, the security system seems to think my door has been opened and it sets off the alarm which is a real hassle for me as I live in an apartment and don't always hear it from inside. I get all kinds of complaints from neighbors about it continually going off as well as things i may have in my car are not secure enough if I keep it unlocked to keep it quiet
What makes this problem better or worse?
it seems to be less problematic when the outside temperature is colder
How long has your 2005 Mercury Mariner had this problem?
since I bought the car, used. About 2 or 3 months.
RepairPal Certified shops can diagnose and repair your 2005 Mercury Mariner. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
The door ajar switch is located 'inside' of the door latch assembly .. *Liberally* spraying WD-40 or the like inside the door latch will usually free up the sticking - malfunctioning door ajar switch.
I have pretty good results with that procedure at the shop... Sometimes using compressed air from the shop air compressor in addition to the lubricant is necessary.
I agree with PushRod's answer - the door ajar switch is inside the door latch/lock actuator. You can try to clean and lubricate it. If that does not work, replacement of the actuator would be required.
