if the indicators work but not the hazards, this is normally the switch. seen lots pack up . if you remove switch and press about, they normally work now and again then new switch.
as for the window if you can hear the motor working and it doesnt sound rough/noisy etc , then chances the plastic retaing clip has off the motor to glass link. if it is noisy then new motor , as above done lots of each.
if no noise at all, check fuses then switches etc. live to motor etc .
did the company have door pad off?
