I was wondering any of y'all know what could be wrong with my AC blower. I checked all the fuses they're good not broken. I check my resistor to see if the metal part had any buildup on it it didn't. So I ended up checking my blower motor took it out and took the fan off and had a lot of black residue like if the motor had burnt. So what I did was I bought a new motor and install the old fan. I ended up installing the new motor and I turned on my car to see if the AC would work and the AC blower still doesn't blow any air. I don't know what else to look for could it be that even the resistor looks good it still could be bad maybe is that what I need to replace. I am just at wit's end and I could use y'all's help anything would be greatly appreciated

The resistor could still be bad, but check the wiring that goes to the blower motor and resistor as it can go bad too (I think it was a bad design that was later updated).

Just as tartilc said, check the wiring that goes to blower motor. It is a bad design. The wiring is too short annd over a period of time it shorts out or tears off. Happened to me. Took it to my mechanic who installed everything over with new harness.

your problem is the power connector under front edge of glove box
You can replace it or simply cut it out- to splice in new segments to the motor.
As noted by others, the resistor failure- located on the back side of blower mounting plate- it has a heat sink you have to remove for inspection
BUT 90% of the time the problem started with power supply then burned out the rest

this happened to me. i checked all the fuses, changed the resistor and nothing worked. Turns out the blower crapped out and took about 6 inches of the harness with it.

more likely the connector failed and took out the wiring and motor
replace or competely remove the connector (solder in new wire segments) under glovebox- the power for cabin fan motor
