Test (jumper) to see if washer motor or switch is broke
Does anyone know how to check to see where the problem lies - the washer motor or the switch on the steering column? I checked fuses and put a new washer motor in, but no success. This leaves the switch, but I think I'll have to remove the steering wheel w/air bag and I hear that is a real mess to do. I want to be sure before I start down this road....

Re: test (jumper) to see if washer motor or switch is...
If you replaced the motor then it is your switch that is bad. Be careful doing this as not to set off your airbag. Un hook both your wires to your battery to really make sure you cover yourself. When airbags go off they hurt especially when you are working on something and they pop. Good luck please rate. Thank you for using FIXYA.COM

Starter motor relay ! Do you know how a starter system works ? Do you know how to do electrical testing , how to read a wiring diagram ? How to voltage drop test starter motor circuit Replacing parts without testing isn't very bright . What the he** is a
ignition actuator, I know what an ignition switch is . ignition actuator , key lock cylinder . Is there a security light lit on the dash , Anti-theft .
First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse
Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.
Don't the wipers work in any mode ?
Did you review the Wiper/Washer System description and operation and perform the necessary inspections?
YES - Go to Step 2
NO - Go to Symptoms - Wiper/Washer Systems
Turn ON the ignition , with the engine OFF.
Operate the windshield wiper/washer switch through all the switch positions.
Does the windshield wiper/washer system operate normally?
YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
NO - Go to Step 3
Turn OFF the ignition.
Disconnect the harness connector of the windshield wiper motor.
Turn the ignition ON, with the engine OFF.
Connect a test lamp from the accessory voltage circuit of the windshield wiper motor to a good ground.
Does the test lamp illuminate?
YES - Go to Step 4
NO - Go to Step 13
Connect a test lamp from the accessory voltage circuit to the ground circuit of the windshield wiper motor.
Does the test lamp illuminate?
YES - Go to Step 5
NO - Go to Step 14
Connect a test lamp from the signal 2 circuit of the windshield wiper switch to a good ground.
Press the windshield washer switch.
Does the test lamp illuminate?
YES - Go to Step 11
NO - Go to Step 6
Let me know if you make it this far and i will send rest of diagnostic's
Check connections to the washer pump motor. Test the pump motor with a jumper from positive power or battery terminal to the
pump positive connection. Double check the negative side (ground) for good connection to the body metal. Corrosion does funny things to electrical connections. Bad pump motor? Replace the pump. If the motor is ok, follow wiring back to a controlling relay. Follow the wire from steering collum switch which could be bad to a relay. Check steering collum switch for voltage when turned on. No luck, Repair manual make, model year possibly at filepeep.com or manualslib.com
this circuit grounds in the steering column by the switch that activates it..did you test the pumpitself? if not you can with a jumper to the motor on the washer tank..see if the pump works use a battery charger so you dont burn up wires..unless you are comfortable that way..good luck..
If the wipers work on normal setting, would not be a relay problem. The intermittent wipers and the washer motor are separate issues-if all on the same stalk, it is probably a bad switch. Hot wire the washer motor with jumper wires to check motor operation. The motor is probably mounted on the bottom of the washer fluid reservoir. Good luck.
yep check fuse.if fuse good check to see if power going to switch if yes.sound like seat motor bad or there is a broke wire at switch going to power seat motor or the switch could be faulty.hot wire the power seat motor using jumper wires.if motor works problem in switch or it wires.if motor dont work it is faulty.
had same problem with 94. in the door jam there is a rubber boot that holds all the wires for your power windows and locks and stuff. remove the boot and check each of the wires in that harness to make sure they are not broke. that's what was wrong with mine on both doors. the wires break with repeated door openings.
Locate wires going into the motor, and with a 12vdc test light, probe one wire at a time for power when switch on, low, med, high. If you get power there, it's your motor, or bad ground. Simply use a jumper wire from known good ground and rub or attach it to metal of blower motor, to test for poor ground, with fan switch on. If no power there, I suspect you have a relay in line too, perhaps shows it in owners manual, in fuse box?
