1. The a/c worked fine yesterday but just now I started the car and now the blower does not have any speed and will only work on high. Hoping someone can tell me what has happened and what needs to be replaced. THank you in advance for any help you can provide. .

 

Blower motor resistor needs to be replaced.

 

Hey, quick question. I Ordered a resistor due to my fan staying on full blast even when I turn the system off and screen for controls goes off. However It did not resolve my issue and Im skeptical whether the part I ordered through carparts.com is defective. I made sure the new resistor is for an automatic climate control. Is there a certain ohm range because on the new one because I'm getting 3.76 m ohms for the top pin to the bottom left pin, and 13.26 k ohms touching the first top pin with the bottom right pin. Seems a bit high but I don't have any range to compare with. The old resistor had exceeded resistance to even read between certain pins so I was sure this would fix it. Thank you for anyone who reads and can help in any way.
