Red face 126 AC problem

So it was spinning and blowing air yesterday.. But today it stopped.. I checked the blower fuse and the kilma.. They looked ok.. What do you guys think.

Before posting , I searched the forum.. And couldn't find anything close to my problem.

I took out the climate control
Unit out today.. Cleaned it and inspected the plugs . Put the whole thing back and still no sign of life...

Thanks guys

Have you check the blower motor under the dashboard on the passenger side? If you hook up a battery to the pos and neg prongs of the blower motor, it should spin. If it doesn't then you will have to replace it. This is what it looks like: http://www.myrecycledparts.com/product_p/12824.htm

Easy, it is under the glove box compartment. You have to remove the carpet piece that are in front of you knees when you are seating. Once you remove this part, you will find a cover that looks like this: http://www.myrecycledparts.com/product_p/12825.htm
Remove it and you will see the blower motor.

Let me know if you need more help.

Took the blower out and connected to the battery.. It spins like a champ so how do I check the regulator.. Or could it be something up the line.. The climate control? Thanks for your help man

There is no easy way to test the blower regulator. It is usually a part that will go bad this is what it looks like and it is next to the blower motor.

Also, the ac control unit may have gone bad. What year and model is your car?
