My heater don't get hot enough on my 92 geo prizm. Can anyone give me any help?

It is a car!

Never had that specific problem but I will attempt to help;
You could start by checking the manual 'valve' that controls the quantity of hot water flowing to your heater core. from inside the car, slide the lever back and forth from hot to cold and walk out to the engine and make sure it is moving the valve appropriately.

I am assuming 92' have manual heat controls.

I have went through the process of limitation. I have checked the valve it works ok. I put a new thermostat in it that didn't help. I have tried flushimg it with a good cleaner. If anything comes up let me know.
