Makita HR3000c green light comes when trigger depressed but doesnt work

From the owner's manual: Indicator lamp The green power-ON indicator lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. If the indicator lamp does not light up and the tool does not start, the ON/OFF switch or the mains cord may be defective.

The easiest to check is the brushes. Most newer tools have brushes with a spring loaded pin in them so when they wear down the pin pops and stops the motor so you don't wear the armature. Even without the pin the wire from the contact to the brush is short so the spring doesn't contact and ruin the armature. If the brushes are OK, you'll have to check the switch for continuity.
