To be clear, I’m not an electrician. Just a weekend warrior. So my blower motor stopped working and this is how I went about diagnosing it and I’m not 100% sure if it’s the correct way. Remove the glove box and you’ll see the blower motor connector in red.
The yellow is your relay that’s secured by a screw you cant see that holds a c clamp around the relay.
I used a test light to check for power at the blower connector with the key on and blower on. Wasn’t getting power so for now I can rule out the motor. When switching the fan speed you should here the relay click. I tested power there and it only came on on one wire when switching from speed 3-4 only. Idk if that’s normal. So I removed the resistor. It’s a pain to remove the two screws. Wear mechanical glove bc the metal around the glove is extremely sharp.
I used a long needle nose in one hand from the bottom and used the other the pull the connector off. It’s held in with two 9/32 screws. 1/4 inch short socket works best.
Off to the parts store.
Hope so his helps someone!
