Question about 1998 Toyota Camry

1 Answer

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....

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

    There should be two screws located on the bottom of the stearing colum. Remove those two screws and you can get the bottom cover off. After that the top cover wont lift all the way off but will realease enough to get the screw driver in there and enough for you to see.

2003 Pontiac Montana wipers not working how to fix


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 ?
1
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

NO - Go to Step 3
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
4
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
5
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

My wiper motor only works on high and stops were ever the wipers are at. And the washer motor doest #39;t work


Low Speed Windshield Wipers
Low speed is activated when the multifunction switch supplies a specific ground to the speed inputs of the windshield wiper motor module. The windshield wiper motor module then supplies ground to only the windshield wiper run/park relay coil, activating it. When the windshield wiper run/park relay is activated, the deactivated high/low relay connects voltage to the windshield wiper motor low input activating the wiper motor. The windshield wiper motor module continues to operate the windshield wiper motor in the same manner as in high speed, but in low speed with the wiper motor connected to the low speed input.
Washer System
The windshield washer is activated by the internal wiper motor module when it receives a ground signal input from the multifunction switch. Dependent on the switch selection, the internal wiper motor module activates the windshield washer relay (internal) by grounding the respective relay coil. When the relay is activated, it connects voltage to the washer pump while the washer level switch provides ground to the washer pump.

    I have problem with windscreen washer,i cant find some fuse or relays,any help,many thanks


    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

    Turn signal switch,intermittent wipers not working correctly,washer not working,is all this controlled by the turn signal switch assembly ? or could it be the wiper relay module and washer pump motor,


    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.

    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.

    Window defroster not running


    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?
