I replaced blinker switch. Because I had no dim light it fixed the problem. But a few days later I went out to finish putting the dash back together and it would turn over but not start. So, I figured it was the TBC fuse for the security lock out thing again. So, a few days later got fuse put it in. Fob would work, no dash lights, I had binging with key for a little bit. Emergency flasher I could hear but not see. Now nothing.

Hi,

It sounds like the battery is discharged. Have you checked? I say that because you may have caused a short at some point and it is draining the battery.

If possible, take a voltmeter or multimeter and see how much voltage is present in the battery. Or try this simple load test on the battery and let me know what you find:

If you have a jumper pack or a means to try jump-starting the engine, give that a try as well. You could also remove the battery and have it load-tested at a parts store. Most do it free of charge.

Let me know what you find.

Take care,

Joe
