You need to disconnect the battery.
Remove the upper and lower steering column shrouding
Remove the torx bolts that holds on the horn pad
Center the steering wheel
Remove the horn pad and disconnect the air bag
Remove the large nut that holds on the steering wheel
Bump to loosen, and remove the steering wheel.
Remove the spiral cable assembly; 4 screws
note: do NOT move the spiral cable left or right; you will damage it.
The combination switch retention screws will now be visible.

All in all, a pretty easy job.

Wipers work when i turn left

You have two options here.

1. Replace the Combination Switch as your Wiper/Washer, Turn Signal, Emergency Flasher and High/Low Head Lights are all in the same switch.

2. Fix the broken wire inside of the switch.

Here are the steps you need:

1. Tilt the stearing wheel up and remove the lower dash panel. (Three 8mm Hex screws)

2. Remove the steel anti-theft place behind the lower dash panel (Five 5/16 Hex screws)

3. Remove the lower stearing column panel (four phillips screws) There is one on the left, three on the right. You will have to look all the way back on the right rear to get this one as it is slightly hidden behind the dash frame.

4. Lift slightly on the upper stearing column panel and remove the two #10 Torx scress that secure the combination switch and disconnect the electrical plugs.

5. Assemble in reverse.

Now, if your problem is related to the delay circuitry of the Wipers, you can remove the 5 Torx screws in the combination switch which will allow you to seperate the two halves. When you do, there will be on plastic contact slide that will come out of the top and you will have to fish this back in when reassembling but it is quite easy.

There will be a three wire plug that also connects to from the top housing and feeds into your turn signal lever. Slide a small screw driver into the lock mechanism and pull free.

These three wires (Red, Blue and Yellow) are what control your wipers and wiper delay. If one of them is broken, you can resolder to fix the problem.

If the wires are not broken, then you likely will have to buy a switch as you cannot get inside of the sealed handle. However, you can use an ohm meter to test the function of the switch.

Total time to remove and replace the switch is about 30 minutes. To disassemble the switch, replair and reinstall is about 1 hour depending on your abilities.

Replace combination wiper switch 2002 Pontiac Bonneville

I just pulled one of these switches from car. You need a t20 torx bit and a flat head screw driver. Disconnect the negative terminal under the backseat so the airbag doesn't go off, the steering wheel doesn't need to be pulled.

My windshield wipers will not turn off and I have no turn signals.

I think your combination switch is malfunctioning. The switches that control both the wipers and the
turn signals are built into the combination switch. And the headlight controls too on some cars.

Your car may have a switch that controls the wipers and the turn signals, but not the headlights.

But whether you have the type that controls wipers/turn signals/headlights or just turn signals/wipers Im not sure, you didnt mention the specific year and model. But you should replace the switch that controls your wipers/signals. They are expensive sometimes, especially if you have the combo switch that controls wipers, headlights and turn signals. But you can find one at a slavage yard for a lot less money than new.

But you should put the year/model of your car when you post a problem youre having. That makes it more likely that someone can help.

Wipper fuse keeps blowing out

As the question is concerned i think it is a electric circuit problem.. So you need to follow these instructions to curb the problem.
You'll need a voltmeter / continuity tester to test the windshield wiper switch, your ground wires and the wiring between the motor & the switch. You should be able to figure out where your problem is and fix it. It's just going to take you time to isolate the problem. If you're not familiar with troubleshooting electrical problems, then you'll have to take your car in to a mechanic or automotive wiring specialist.

How do i remove the turn signal switch from a 1984 nissan 300zx?

What you really want to remove is the "Combination Switch" which controls the
a) headlights b) turn signals, and c) windshield wipers.
The new switch comes with the Left-hand handle attached (expect to pay $$$).

I found your solution (with illustration and replacement parts) at
Autozone will expect you to register with the site - free. Since your car is a 1984, buy
a Haynes manual - $20 anywhere (try Pep Boys, Advance Auto Parts, etc.)

(I don't work for Autozone) Autozone sells 2 replacement switches:
the one you want is: Duralast SW1836 $122.99 - it has the combination switch and handle only.
They also sell: Duralast SW1690 $170.99, which has the combination switch/handle and also a
collar going around the steering wheel and another switch and handle on the right side of the column.

1. remove steering column cover.
2. unfasten the wiper switch electrical connector.
3. remove the wiper switch-to-combination switch retaining screws, then pull the wiper switch off of the combination switch.
4. The combination switch is now disconnected and can be removed.
5. Installation of new part is reverse of removal.

My windshield wipers (front) on a 2000 dodge grand caravan go off and on on their own. They wont work most of the time but they will just pop on on their own or if u turn the lights or high beams off and...

My best guess is the switch is bad. Did you replace it? The problem could also be the bcm, but I would test the switch first. Remove it and check it with an ohmmeter.


Turn Signal Switch

The Supplemental Inflatable Restraint (SIR) system must be disarmed before working around the air bag or SIR system wiring. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.

  1. Disconnect and isolate the negative battery cable from the battery.
  2. In order to disarm the air bag system, allow the system capacitor to discharge for at least 2 minutes, before performing any removal procedures.
  3. Remove the upper and lower steering column shrouds.
  4. Disconnect the electrical connector from behind the combination switch.
  5. Remove the mounting screws securing the combination switch to the steering column adapter collar.
  6. Remove the combination switch from the vehicle.
To install:
  1. Install the combination switch to the steering column adapter collar. Tighten the combination switch mounting screws.
  2. Reconnect the electrical connector to the combination switch.
  3. Install the upper and lower steering column shrouds and tighten the retaining screws.
  4. Reconnect the negative battery cable and check all functions of the combination switch for proper operation.

From the service manual, which is available relatively inexpensive at here

 Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room)
 Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM (body control module)
 BCM controls front wiper LO, HI, and INT (intermittent) operation
 IPDM E/R operates the wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times
 through 50A fusible link (letter f , located in the fuse and fusible link box)
 to BCM terminal 70, and
 through 20A fuse (No. 39, located in the IPDM E/R)
 to front wiper relay, located in the IPDM E/R
With the ignition switch in ON or START position, power is supplied at all times
 through 10A fuse [No. 1, located in the fuse block (J/B)]
