Further ideas. The heater and defroster have an electric motor that moves the air, is the motor burned out? Need to check that, too.
Turn signals, need a working flasher unit, to work properly, as well as four working turn signal bulbs. Check the flasher unit, located under the dash, silver round thingy with prongs that go into the fuse block, left side under dash. Check the turn signal and brake light bulbs, for proper operation , too.

Check fuse, bulbs, and flasher relay.
Check fuses and turn signal flasher
