So I've read the previous post regarded issues with a blower motor resistor and what not. As helpful as it was it didn't fix my issue. I have a manual HVAC system(Knobs) and no climate control. I get no response from my control knobs.

My issue started about 6 months ago. I was able to turn on the heat and it would jump all over the place with fan speeds or turn off completely. Eventually it just stopped working. Tonight a buddy and me went through some pretty redneck troubleshooting to try to determine the issue.

1. We checked the two fuses on the left side of the dash and they are both fine.

2. We removed the motor from the dash and tested with a battery. The fan turns when it gets electricity.

3. I stopped at my local autoparts store and replaced the resistor because the original looked like it had seen better days and from what i read it was the next logical step.

We had a multi-meter to start the night off but for some reason it decided to crap out on us. I would imagine the next step is to make sure that the clip that plugs into the resistor is getting juice. If anyone can throw some idea's my way I would greatly appreciate it.

Now upon replacing the resistor I am still getting NO power to the motor from what it seems.
