96 Honda Civic. In cold weather, headlights won't come on unless high/low dimmer switch is pulled towards driver. As long as the switch is held in that position, the headlights work. After a couple of minutes, the headlights will continue to work normally, but if the switch is released too soon, the headlights go off.
I was told it is the dimmer switch, but I have been told that it is part of a 'combo switch' and the whole thing needs to be replaced and I have been told that it is possible to replace only the dimmer switch itself. Which is correct (if either)?
Can anyone give me instructions for replacing the needed part?
Re: 96 Honda Civic. In cold weather, headlights won't...
The "dimmer switch" is part of the combination switch. They wear down, internally - I've taken apart a used one, so I know. Also, the headlamp connectors like to corrode on that model year ( I also have 96 civic, and had to replace a headlamp connector). https://www.hondapartsnow.com/parts-list/1996-honda-civic-4dr_ex-ka-4at/combination-switch.html (parts 8 and 9)

Here is how they are suppose to work .
The headlamps may be turned on two different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the OFF position, for automatic lamp control (ALC). During ALC, the headlamps will be in day time running lamp (DRL) operation in daylight conditions, or low beam operation in low light conditions. The LH HDLPand RH HDLP fuses, supply battery positive voltage from the underhood junction block to the left and right headlamps. The circuit continues through both low and high beam lamps, then back to the underhood junction block. The low beam and high beam circuits continue to the headlamp switch. The low beam and high beam circuits also provide the body control module (BCM) with both low and high beam inputs. The headlamp switch includes the dimmer switch and the flash-to-pass switch. When the headlamp switch is placed in the HEADLAMP position a path to ground is provided. Ground is provided at G201. Depending on the position of the high/low beam switch, either the low or high beam circuit will now have power and ground.
The LH HDLP fuse in the underhood junction block, supplies battery positive voltage to the automatic lamp control (ALC) headlamp relay coil circuit. The ALC relay switch circuit is connected to the low beam circuit at the headlamp switch. When the headlamp switch is placed in the OFF position, the BCM will automatically turn on the low beams in low light conditions. The BCM energizes the ALC relay, closing the switch contacts and grounding the low beam circuit. Ground is provided at G201. With the headlights in the low beam position, the high beams may be momentarily turned on or flashed with the dimmer switch handle. The flash-to-pass feature is accomplished by pulling the dimmer switch handle toward the driver. The headlights may be switched to high beam with the opposite movement of the dimmer switch lever. When the headlamp dimmer switch handle is pulled toward the driver, the flash-to-pass switch closes grounding the high beam circuit. Ground is provided at G201. Both high beams will remain on until the driver releases the switch handle.
If the driver places the headlight switch in the HEADLAMP position , the headlights will remain on until turned off or the battery runs dead.
Both the headlight switch and the BCM provide a ground, or control circuit, to the headlight relay coil circuit for manual or automatic headlamp operation. When you place the headlamp switch in the OFF position, and the ambient light sensor indicates low light conditions, the BCM energizes the headlamp relay for low beam operation. You may switch the headlights to high beam by pulling the dimmer switch handle toward you until the dimmer switch is activated. When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp.
Low and High Beams Headlamps Inoperative ?
Replace the headlamp switch. Refer to Headlamp Switch Replacement .
Did you check the headlamp relay ? Location ,left instrument panel
If your high beams come on only when you hold the lever, and you have no headlights otherwise, i would suggest it has to be the dimmer switch that is faulty. First, though, use a test light to see if you have power to the low beams. Just pull the bulb out, and test in the socket. If you have power there, the problem is just the bulbs. No... they didn't both burn out at once, but you don't notice until they are both gone. You meet cars all the time with one headlight. When the second one goes, they over think the problem.
The fact that your dimmer switch has to be held to get any headlights would lead me to believe it's the dimmer switch that is faulty.
I have a 2004 ram 2500 and all my lights work except for low beams. It is not in the switch, I haver replaced the switch with no change. This is a circuit problem with these dodge pickups. I haven't firgured out what it is but it isn't the switch. and unless the low beams and high beams are fused seperate, it isn't a fuse problem either. i have looked for a fuse and can't even find the fuse for the headlights. Im lost like you!
In 96-98 Civics the dimmer simply pushes in under the left dash vent and is held in place on both sides by metal flexing tabs (no screws). If it were possible to grab it you could pull it straight out with a bit of rocking / side to side motion to help to release it. Unfortunately the proper way to remove it requires removing the lower panel as follows:
You need to remove the plastic cover panel that is underneath the steering column (the one with the switches, coin pocket, and fuse box cover built in). To do this you remove three screws (one above the switches on the upper left, one in the lower left corner, and one on the lower right. You will then need to pull the bottom edge out slightly from the dash and tug the entire panel down towards the floor of the car as gently as possible. You will be pulling out three metal snap-in retainers at the top of the panel, two on the left and one on the right. It is often hard to remove plastic panels without damaging them so be careful. Now unplug the switches (mirror, sunroof, fog light) and set the panel aside. At this point you can easily reach behind the dimmer switch, push it out, pull it through the front of the dash, and unplug it.
