Heater/ac blower issue

My heat and ac work great, gets real hot or cold. My problem is the position 3 on the blower doesn't work. I'm guessing it's electrical, but I'm not sure. It's not a big deal, I would just like to fix. Did anyone else have this issue before?

Yes, that would be your blower motor resistor network. As seen here.

Sounds like your blower motor resistor.

Is that located behind the position switch or somewhere else?

OK, thanks a lot. I'll probably be ordering one soon and fixing it up.

Don't get a used one from ebay or junkyard unless you are selling the car tomorrow. This part in particular is better bought new. I purcased one for my moms Cavalier for 32$.

Sorry for the super long reply wait. I haven't purchased one yet, but I will buy new. I don't have a problem with 3 not working for now. Eventually it will be fixed
