I am trying to tie up some loose ends regarding the relays in the fuse panel. Let me first ask the question, is this the right functionality/description of each?

1st round relay ( closest to driver door) - buzzer, controls the door buzzer when the key is in and the door is open

2nd round relay - aux lights, Controls the fog lights

3rd round relay - fresh air box, controls wipers, fresh air box, horn?

4th square relay - headlight dimmer, controls high beam low beam?

5th round metal relay (behind square relay) - don't know

I had been having an issue with my fresh air and wipers and believe that the relay was the cause. It would work intermittently and even keep the fresh air on after the car was turned off. I swapped in a used one I got off ebay, but it didn't seem to fix it. I then swapped it with one of the other 2. It worked and I was able to turn on the wipers and fresh air. When I turned off the car the fresh air would stop. I was not able to hit the horn button when the car was not on.

Question 2 does your horn work if the car is off?

I swapped in the supposed faulty relay into the fog light position and it worked.

Question 3 can part of the relay fail to function, but in other spots it work?

Question 4 how can you test a relay to ensure it works?

Question 5 does anyone know which accessories work when the car is off besides the running lights and hazards?

Thanks!
