This is common when the ignition switch goes out. To be sure, here is a guide to help you to test for power at the brown, yellow, pink, and orange wire with the ignition switch on. You should do the test when the gauges etc., are not working.

I've already changed the ignition switch out twice thinking that it was it because that was it on the first one it worked for about a week on this one and then now, I got the issue of the indicator light on the shift is not working but now I turn the heater on and indicated like won't work at all turn the heater off indicator light works now what's the issue.

That sounds like a bad ground, I would check the under dash ground points, here are the locations in the diagrams below.
