My air conditioner was working, but the blower motor was making a very loud noise and vibrating the dash. After a few days, I went to turn it on to show a friend the noise for advice. The motor would not come on at all. I replaced the relay and the blower motor. I also cleaned out all the leaves and debris behind the resistor. The same results though. Nothing happens when I turn the switch on. What could it be?

I have been on "Prodemand"

I have found a diagram (it had two choices-Limited and SR-5) I chose the Limited, the diagrams maybe the same for the air conditioner circuits, if not, I will get the other for you.

I can only screenshot the diagrams in Prodemand.

It took three shots, they overlap, so there is no missing information.

Picture one is top/ two is middle/ three is bottom.

Locations of the components are listed, the blower itself is on the first diagram sort of bottom right.

Keep us posted on progress!
