Heater switch only works with level 4. Levels 1, 2, 3 don't work. Is it a switch problem? Please let me know, thanks

No, that will most likely be a bad blower motor resister. It's located in the blower housing, right next to the blower motor.

Yes, most likely. In rare cases it can be the switch but 9 out of 10 times it's the resister.
