Question AC Blower Fan Relay???

Blower fan stopped working on AC unit in automatic mode. Will not come on when stat is set to Fan on. Getting 24v between R and G so the transformer is okay. Also getting 24v between C and G so I figure it is a bad fan relay right? Fan motor spins fine by hand so bearings on motor are good. This is a combo heating-air conditioning unit, horizontal in attic. Any help greatly appreciated.

Get a piece of wire and jumper across R and G. Does the fan come on? If so, might have a bad thermostat. If not, might have a bad fan motor, fan capacitor, board, or fan relay.

Thanks for the reply. As I suspected and lucky for me a new $8.00 fan relay did the trick. Don't even know what service calls cost these days and I know I would have been charged $30 for the part, so thanks to what I learned by sifting through similar problems, it's fixed.
