So, like the title says, I'm having a bit of an issue with some electrical crap in my car. I have a 93 miata and have done the following already:
- Checked all fuses both inside and under the hood. Everything checks out.
- Removed and cleaned the ignition switch
- Removed and cleaned the window switches, and radio connection
And still, nothing works. I've exhausted all of my knowledge, and need some help or suggestions. Thanks.

That’s all dash harness stuff. Is this a sudden development or was there recent work/modifications performed?
It's a sudden development. I took out the TNS and headlight relay yesterday to get part numbers, and nothing has worked since.

Upon further inspection, the power mirrors also don't work. Could I just have a bad ignition switch? I took it out and polished the connections. It was in a pretty bad way.

Perhaps it is the ign switch, as those items you are having trouble with are on switched power ( not sure about the power mirrors though ). Does the car start and run?
Car starts and runs fine. The AC/heat blower works as well.Quote:

Man, that is weird. There is a big cluster of grounds near that TNS relay, maybe poking around near there broke some? I had to fix some corrosion on mine there when I swapped harnesses. I might also look under the dash, driver’s side, and behind the radio for loose connections.
The FSM does a decent job in the schematics for wire tracing.
Good luck! Sorry I can’t help more. Please report back when you solve it!
It was the ignition switch. Replaced it with a new one and it works like new.
