1996 Jetta testing the headlight switch

1996 Jetta how do I go about testing the headlight switch? Where can I find a diagram of the terminal layout on the back of the switch? I just want to make sure the switch is the problem before I dump $100 on a new one. Any advice in diagnosing the headlight prob is appreciated. Marker/tail lights and the like come onwith the switch, but the brights will only come on momentarily when I use the dimmer switch, and the low beams won't come on at all. I jumpered the wire and they lit up, so its not the bulb or something silly like that, fuses are also fine.

Use a test lamp to see if there is current going through the low beam fuses when the headlight switch is turned on. Do your daytime running lights go on?

There is usually a relay under the hood that controls these. They could be run in a series which would explain your lack of a blower motor also. Good Luck.

  1. Open the vehicle's hood and secure it in an upright position.
  2. Disconnect the negative battery cable.
  3. Remove the socket cover by pulling it straight off, or turning it clockwise then pulling it off.
  4. Carefully twist the bulb and socket counterclockwise, then pull the assembly from the headlight housing.
  5. Holding the base of the bulb, detach it from the connector harness.

To install:
  1. Holding the base of the bulb, install it securely in the connector.
  2. Install the connector and bulb assembly in the housing and twist to lock into position.
  3. Install the sealing cover by pushing it on and/or turning it counterclockwise. Make sure the cover is installed securely or the lens will be out of focus, or water may get into the light unit.
  4. Disconnect the negative battery cable and check the headlight operation.

SOURCE: 2004 jetta headlights going out when switching low/high beams

There is no recall regarding the headlights on that vehicle.

What typically happens is the wiring inside the light housing melts and the bare wires randomly touch each other.

You can verify this by taking one of the plastic covers off the back of a headlamp housing and checking out the three wire harness inside. It is extremely common for this to occur on that vehicle.
The wiring can be repaired, though difficult without removing the lamp.
If you wish to replace the wiring with factory replacement parts, there is no service parts for the lamp, you must replace the entire housing unfortunately. For this reason most people just repair the melted wires.

Headlight Switch

ABCDEFGHIJKLMNOPQRSTUVWXYZ The headlight switch controls most of the vehicle's lighting systems. Many complaints concerning the lighting systems can be the result of a faulty headlight switch. For example, dim or no instrument panel lights, dim or no headlights, dim or no parking lights, and improperly operating dome lights can all be caused by the headlight switch.
Dash-Mounted Switches
f36-12.jpg A headlight switch. You'll need to remove the switch to test it. With the switch removed it can be tested for continuity and the connector plug will serve as a test point for the lighting circuits. First test at the connector.
In this procedure the terminals are identified as follows:
  • Terminal B = battery
  • Terminal A = fuse
  • Terminal H = headlights
  • Terminal R = rear park and side marker lights
  • Terminal I = instrument panel lights
  • Terminal D1 = dome feed light
  • Terminal D2 = dome light
Consult the service manual for terminal identification for the vehicle you are working on. If this is not listed in a separate chart, you should be able to identify the circuits from the wiring diagram.
  • Connect the 12-volt test light across terminal B and ground. The test light should light. If not, there is an open in the circuit back to the battery.
f_aee_cc14.19.jpg Testing for battery voltage to the connector. Reprinted with permission of Ford Motor Company.
  • Connect the test light across terminal A and ground. The test light should come on. If not, repair the circuit back to the fuse panel.
  • Connect a jumper wire between terminals B and H. The headlights should come on. If the headlights fail to turn on, trace the H circuit to the headlights. Also check the ground circuit side from the headlights.
  • Connect a jumper wire between terminals A and R. The rear lamps should illuminate. If not, trace the circuit to the rear lights. Also check the ground return path.
  • Connect a jumper wire between terminals A and I. The instrument panel lights should come on. If not, trace the circuit to the panel lights.
The chart below indicates the test results that should be obtained when testing the headlight switch for continuity. use an ohmmeter or a self-powered test light to test the switch.
Steering Column-Mounted Switches
On some vehicles it is possible to test the steering column-mounted switch without removing it. The test is conducted at the connector at the base of the column. However, on some vehicles it is necessary to remove the column cover and/or steering wheel to gain access.

2005 cavalier no low beam or drl lights need wiring diagram

Hi, the problem may be the body control module, the DRL relay, or the DRL resistor. The relay is in the fuse box under the dash. Pull out the relay and check the socket with a voltmeter or test light. With the headlight switch full on, there should be 3 ground terminals in the socket and one hot terminal. With the headlight switch off, there should be 2 ground terminals and one hot terminal. If there are the proper number of ground terminals, replace the relay. If not, check the DRL resistor for an open condition. If the number of ground terminals does not change with the headlight switch on, replace the switch. If everything checks out OK, replace the BCM. Please let me know if you have questions, and thanks for using FixYa.

1996 vw jetta problem with the headlights. The daytime running lights work fine the high beams work fine, but when you turn on the lights from the switch the driver side headlight turns off. I've checked...

I don't have a wiring diagram ,but on most cars I would say your low beam bulb is bad. Try swapping sides to see if the problem goes with it, or just replace the bulb. You can always keep the new one until needed someday... shadetree mech by necessity.

My headlights stopped working on my 1996 dodge dakota and i need to know what to look for to fix the problem.

First check fuse. If OK, find headlight relay in relay box under hood. Turn on lights, pull relay out, and use a test light to test each terminal in the socket for power. There should be 2 hot terminals, one from th ebattery and one from the switch. If you have only one, your switch or wiring are bad. Next, plug the relay back in and listen for a click as you do. If you had 2 hot terminals, the relay should click. If not, replace the relay. If you have 2 hopt terminals and the relay is working, the problem is in the wiring going form the relay box to the headlights. If you have more questions, please let us know.

Where can I find the electrical specs? the blinkers both stopped working. The hazard blinkers do work.

Any other strange electrical issues? Headlights, blower, wipers?
Its quite possibly the ignition switch. Just had to replace it on my daughter's 97 jetta. She had first the blinkers behaving erratically, then it was random electrical issues after that. At first we were sure it was in the combination switch, or the arms off the steering column that operate the blinkers, wipers etc. Unfortunately, that change didn't fix it. After a bit more research I learned the ignition switch on these creates these symptoms. Changing the switch wasn't very difficult with a diagram and a bit of experience and the part was only about 30.00.
Hope I've helped -Good luck!

Headlights stay on in 91 festiva ! with switch turned off

The headlight switch is most likely defective. If you can get to the back of the switch you can do a continuity test to see if the switch is opening and closing.
