  1. Do you have a auto or manual climate control?
  2. Do you own a test light or volt meter, so we can diagnose this?

Manual or automatic, can you control the driver and passenger temp independent of each other, if so its auto.

Thanks, ***** ***** hood remove the blower relay. Start the vehicle and turn the HVAC on. At the relay pins you should be getting power all the time on pin 3, power with the key on pin 1, ground from the HVAC on pin 2. Below is a link to a relay diagram.

Let me know which is not working right, and if all are working then get the blower into a none working state and do the tests again. I will be gone for a few hours after this post for a dinner date but will be back later.

Well the damn thing started working then I turned off it wouldn't come back on then it came back on an I heard a motor noise though what seamed through speakers any ideas

You would test pin 1 the same way you checked pin 3.

Pin 2 ground you connect your test light to battery power and probe pin 2 to see if the light comes on from pin 2 providing a ground.
