Wipers don't work, horn doesnt work low beams don't work, blinkers don't work (hazards do), brake lights don't work. Every other light works. Is there a common connection for all these? They all stopped at the same time.
Did you check the fusebox? Which would be the first thing to check. Don't do a visual check but instead use a multimeter.

Bumping this thread because it's still an issue. I've gotten the low beams to work and tracked it to the wrong relay put in by the previous owner.
However brake lights, wipers, and blinkers do not work. The hazards work and all the bulbs have been tested.
Is there a common connection for all of these? They all went out at the same exact time.
I can't think of any common problem that would cause this. I was thinking an unloader relay could be mixed up, but that will only shut off the wipers. I had an E30 with a damaged fuse box circuit board that caused all sorts of fun, but that's rare.
Did the car have a security system installed? Back in the day these aftermarket systems would usually tap into all sorts of fun places...like the flashers/blinkers, horn, start signal, ignition coil + and sometimes use the brake light as a power source.

The car is bone stock. Nothing was added or deleted. Just a really weird gremlin.
Do those components all use a common ground under the steering shaft somewhere? Maybe not the brake lights, but the rest should have a ground on the steering column. I feel I should know this, but I don't recall where the column is grounded out. Probably on the firewall, anyone know offhand?
It just occurred to me that I had a similar problem last year. My turn signal switch was flaky, it caused random headlight flickering. Sometimes a pin gets bent or damaged inside the connectors too.
