Re: '94 100 S Avant, V6 automatic non-quattro. The hazards (or both turn
signals) come on when the turn signal switch is moved left or right.

He replaced the hazard light switch with a used one -- no change.
He then replaced the turn signal switch with a used one -- no change.

I assume the used switches were good, as they were sourced from Force 5.

Probably not the ignition switch, as the other electrics (sunroof, wipers,
heater fan, etc.) still seem to work normally.

The problem started when he opened a door and the alarm went off. He canceled
the alarm, and then when he put on the turn signal (left or right), both
would come on like hazard lights.

We'll try the blinker relay next, and then ...?  Chris Semple suggested
following the Bentley wiring diagram, which I don't have.

Any other suggestions (besides, "It's an old Audi, what do you expect?"?).
