Bosch GBH 24 VF drill fault

[andyshed]

Hi all this is my first post so i will thank you in advance.

I have a bosch gbh 24 vf battery drill and all was going well until today.
My battery is fully charged but when i pull the trigger....nothing.

If i press the trigger then manually turn the chuck it all springs in to life, release the trigger and try again (without turning chuck) nothing.

Has my baby gone for good or a fixable problem ?.

Thank you.

Brushes would be the first thing to look at and the cleanliness of the commutator they run on
