Default Electrical problem

Lately the heater blower and the turn signals randomly stop working at the same time.

This is preceded by a loud buzzing sound under the dash to the left of the steering wheel, close to the fuse box.

Whenever the buzzing starts, neither the heater blower nor the turn signals work anymore. The buzzing stops after a few seconds but the turn signals and the blower stay dead for a random amount of time - from seconds to hours.

Is there a relay to the left of the steering column that switches power to both the blower and the turn signal stalk? If I push the hazard button, the lights do blink correctly...

Default There are a bank of relays in that general area...>>

Under the lower dash cover, on the left up near the firewall...

It does sound like a relay issue..

Turns and hazards, while located in the same part, are two completely different circuits...
