The heater in my 93 civic refuses to work. The fuses are good, it just seems like there is no power going to it. I can’t figure out what the problem is. The unit won’t power up. I don’t have any sort of electrical tester to see if power is actually going to it. Any ideas what to do?

If your fans are working, but no warm air…

You problem is likely the cable adjustment leading from the dial to the valve in the engine bay. Or it is possible there is a blockage in your heater core.
