2003 ford focus zx5 door ajar indicator lights remains on for some reason getting a signal that the rear hatch is open when it is indeed shut tightly. It appears to be the rear hatch specifically because the hatch compartment convenience light remains illuminated. Is there a switch that I can replace?

The switches that control the lights for open doors are made right into the door latches and they have a history of sticking and causing problems like that.

Here is a technique that often works well and eliminates the problem at no cost.

Get a can of spray lube like WD40 or something like it and has a straw on the nozzle. Spray it generously up into the latch mechanism. Now open and close the door numerous times to work it in. Repeat this process several times.

Thanks for the quick reply. I had actually given this a shot yesterday thinking that maybe some WD40 might "loosen things up." Unfortunately, even after repeating today, that didn't cure the issue. If you have any additional insight, I'd appreciate it.

Then you'll probably have to replace the switch. You will have to contact the dealer to determine if it's sold separately from the latch.
