I have a 2009 Hyundai Sonata v6 that I bought with no air conditioning. The blower doesn't kick at all. I started with the fuses and they all looked fine, I also swapped every single fuse that says AC, blower, or condenser on it with new fuses. I also put a new resistor and blower relay with no luck. I could also test the blower itself and the switch knob by taking off the blower relay cover and connecting the two metal pieces inside the relay and the blower started kicking, and I tried to change the fan speed and it worked. Now I'm sure it's not the switch, resistor, fuses, nor the relay. But the blower still won't run at all, either on AC nor heat. What else could it be?
Sorry to hear you've had so much trouble fixing the HVAC on your Hyundai Sonata. It sounds like it might be time for you to take your Hyundai Sonata to a technician to help identify the problem.
