What is the issue? No air or sporadic operation Check or replace the fan speed resistor (very common)

I replaced the blower motor resistor and it's not that i was wondering if there is a relay or something else?

Dude I just read on this. There is a motor relay. Its has a part inside that is for the high fan speed for when the high fan switch is on high. When its lower than high the resistor comes into play. Makes sense its not your resistor. I would check the motor if its spining at the max speed. Trace for any frayed wires ect. first. Check if your switch is also working. Sounds like relay to me too.
