Nope. No resistor.
Firstly, there are two blower motors, one on each side, wired in parallel. Are they both working?
2ndly, the motors are 4 wire, one for each speed, plus ground. Between the two motors, once the cover is off, there are two relays. They control which of the 3 blower wires gets power, iirc.
So, foregoing the "is there a relay" question, I'd start at the blower switch, testing for output at each of the ON positions first.
