My AC works fine, but my heater only blows hot air very mildly/softly.

It still blows out hot air but barely blows.

I was looking at a blower fan/resistor replacement but I was wondering if the blower is the same for the AC as it is for the heater?

The cold works fine, so I'm trying to isolate the trouble.

I've checked the vents, and they seem to be opening/closing correctly, so I'm not sure what is next to check besides the blower(if the blower is heat-specific) components.
