I own a 2005 Ford Focus 4-door sedan. The button on the FOB and button on the dashboard to open the trunk no longer works. I can hear a click inside the car when I push the button. It started about 6 months ago. I have been using the key to open the trunk. I tried a few weeks ago and the push of the button (on both FOB and dash) would make the lock work when the trunk lid was open but not to open the trunk. The button worked until the lid was several inches above closing but stopped working when it was shut or almost shut. I tried again today and it only gives a click inside the car when you push the button. Does anybody know how to fix this problem. The FOB works fine with the door locks.

The click should be the latch solenoid firing so the signal should be fine I wouldn't think the FOB is the issue.
My bet is that the solenoid does not have enough power to disengage the latch try spraying some penetrating oil (WD-40 or similar) onto the latch claw and latch pin to see if that helps loosen it up.
If you don't have any penetrating oil you could use a small amount of grease or maybe even a small amount of cooking oil for the time being just to see if the lubrication helps. If it doesn't you may need a new solenoid/actuator.
I'd start by checking Fuse#34 (20A) in the driver side underdash fusebox.
If that fuse is fine I'd investigate voltage @ the release solenoid itself. Looks like the white/green wire should get 12V when trunk pop is activated.
If that signal is good you may have a bad solenoid.
