Have a 2001 Kia spectra 1.8L,Problem is blower motor is not working when speed selector is turned on.We replaced the blower motor resistor and still nothing,we took motor out and wired it direct to battery and it spun so its good,there is no power at plug that connects to the back of selector switches what could cause that fuses are good and relays are good i assume, we changed them out and still nothing any ideas.Thanks

There isn't supposed to be any power coming out of the switch. The motor receives constant power on the Red with white wire. Check for that.

So there is no power to the plug that plugs into back of blower speed selector on dash even with ignition on?

That's what i said.
The switch controls the ground side of the circuit and the motor is powered all the time.

Ok thanks so if there is power on that red/white wire what could be wrong? and if there isn't what could be wrong?

One step at a time. Check that and we'll go from there.

Ok we got power to the plug for blower motor checked with voltmeter,so what we did was take a wire plugged it into the ground on the blower plug then used the power from the radio and touched them to the motor and it works on all speeds but soon as you use the power from the blower plug it wont work,also we put wires in the blower plug and used gator clips to touch motor prongs and it goes from 12 volts to nothing soon as the you touch em to motor.

I have no idea what you are connecting to what here. You need to stop jumping wires around before you fry something. As I stated, the motor gets constant power and the switch routes the ground to various resisters for the speeds.
If you know how to test for ground, you can do that on the various speed wires coming out of the switch to test whether it's the switch or the resister.

To be more clear we used the constant power from radio and the motor worked on all speeds soon as you use the power from blower motor plug it dont work but there is power to the plug and soon as you hook the motor up the power goes away if that is more clear sorry about that.

OK, then you have a connection problem on that side of the circuit.
That power comes from the blower motor relay which is #61 in the picture.
Make sure none of the contact plugs aren't burnt in the relay socket.

You're going to need some electrical knowledge to follow that wiring diagram to find out where the issue is.
You might try swapping that relay with another one, just don't take it from something important.

We done did that and same result,I have a question for time being could I take the correct gauge wire with connectors and put one end in the ground on the plug then to the motor for ground,then take wire from the battery to a toggle switch then to the power side of the motor for power and just turn it on and off that way?

Hell no. I don't even want to tell you what we call messes like that. The circuit goes through a relay for a reason. Fix it right or don't fix it at all.

I gave you the wiring diagram. It's just a matter of tracing the circuit until you find the problem but like I already said, it you don't have any electrical knowledge, someone else is going to have to do this.

Your making this too hard, pull the plug of the blower motor and check voltage there at the plug, WITH the ignition ON, AND, AND the blower switch in the high position. Do you have 12 volts at the plug then? Reply back with the results, this is a very simple circuit, shouldn't be hard to trace out. If you do not have 12 volts, then using your volt meter and using the car battery first test with the meter positive probe on bat + and negative probe in blower motor conn. plug on negative side, what about now? Then test with the meter negative probe on the batt - and the meter positive probe in the blower motor conn. plug positive term. What then? The answers to those will tell you where the fault lies.
