Tried fixing my chirping AC......and now it only works on high

As the title says I tried geting rid of the annoying chirp in my ac today. I tried the method of adjusting the screws to balance it out or whatever so that it doesnt chirp anymore. After adjusting one of the two screws for a couple minutes to try and find the sweet spot where it didnt chirp anymore, it didnt work on the lower settings. However it does work on the high setting. I have replaced the HVAC blower resistor before because of the lower settings not working and im hoping thats all that is wrong with it now. Do yall think I should be ok? I already ordered another resistor hoping it will fix it, idk what else it could be
