Bad power switch - Revlon Health & Beauty

If you are getting power to the switch, make sure you are getting power to the motors when the switch is moved. If so, make sure the motors have a good ground. If not, check the fuse box. If you have power to the switch and the switch is sending power to the motor and the motor has a good ground. you have a bad motor. If you have power to the switch, but are not getting power to the motor, you have a bad switch. If you don't have power to the switch, you might have a bad fuse. If you don't have power to the fuse, you might need to check a wiring diagram to see what feed power to that circuit in the fuse box.

Power fuse 30A in instrument panel junction box. Power flow from fuse to the Power main relay. From there it goes to the master switch. Check for battery voltage on the black wire at the master switch with engine running. If you're getting power there, the problem is either a bad master switch, bad wiring from switch to window motor or a bad window motor.

if I am understanding you right the fan isn't blowing anything. this could be a couple of things it could be a blown fuse, a bad relay, a bad switch, a bad fan motor, or a bad wire. I would start with checking the fuses and relay if they are all good I would see if there is power to the motor when it is on if there is power it is ether a bad motor or bad resistors if your fan runs on high but nothing else it is probably the resistors if nothing works it is probably the motor. if there is no power at the motor when there should be I would check for power at the switch if there is power going into the switch but no power coming out of the switch the switch is probably bad. if there is no power going to the switch you may have a brake in a wire if there is power coming out from the switch but no power at the fan you may have a brake in a wire if you suspect a brake in a wire you can test the resistance going throw the wire by setting a dvom to resistance and touching the positive lead to one end of a wire and the negative lead to the other end of the same wire high resistance bad wire no resistance good wire make sure there is no power going throw the wire when you test is though or it could throw off the test.

Hi,

Remove the switch and see if the switch is bad or if the motor has went bad...

If there is power through the switch then it is the motor...

If there is no power through the switch then the switch is bad...

Suggest you see if the problem is the Power On switch, or the Power Supply.

(First check to see if the receptacle in the surge protector, that the computer is plugged into, has power.
Have had a few bad surge protectors, where just THAT receptacle was bad.

"Hmmm, surge protector power on LED light is lit. Monitor, printer, and router have power, that are plugged into the surge protector.

Plugged a lamp into THAT receptacle, and found it to be bad)

To test whether the Power On switch, or the Power Supply is bad, a jumper wire is used to bypass the Power On switch.

[ The Power On switch is located inside the plastic Power On button.
This is an example of a generic ATX Power On switch, that I have found fits many computers,

The jumper wire is used on the 20, or 24-pin ATX main power cable's connector.
While still plugged into the motherboard.

The jumper wire connects to the Soft Power On wire, (Green), and to any Ground wire. (Black)

Example of a 20-pin ATX main power cable, and it's respective connector,

Using the jumper (Wire) to bypass the Power On switch, turns the Power Supply on?
The problem is a bad Power On switch.

Using the jumper to bypass the Power On switch, does Not turn the Power Supply on?
The problem is a bad Power Supply.

There is a correct procedure for performing this test.

Suggestion is to bypass the Power On switch, to see if the problem is the Power On switch, or a bad Power Supply.

If upon bypassing the Power On switch, results in the Power Supply coming on, the problem is a bad Power On switch.

If bypassing the Power on switch results in the Power Supply does Not come on, the problem is a bad Power Supply.

I would like to refer you to a previous problem, that I just gave a solution to concerning this,

you can test the voltage that comes out of the switch, if no voltage, then switch is bad. If there is 12 volts coming out then the motor is bad or dirty.

Bad Power On switch, (Located behind the Power On button), or bad power supply.

There is a technique to bypass the Power On switch, in order to see if the switch is bad, or the power supply.

Bad or borken wire harness in the steering coloum. check power to brake switch, should have power on one side, if not check the fuse if fuse is good and you have no power then your turn signal switch or harness is bad.

check to see if you have power to the window motor.. if so then the window motor is bad, if not the switch is bad...good luck keith...
