Question about 1992 GMC Yukon

What is this switch below the light switch for?

Below the rocker switch for turning the headlights on/off, is a small slide switch. The writing by it is unreadable and it doesn't seem to do anything noticeable. What is this switch used for? Thanks in advance for the assistance.

I have a very clean 89 Crown Victoria from Florida! An old lady owned it bought brand new! I resently replaced all external lights now when I turn on my lights all my front turn signal lights my dash...


The dimmer switch for the headlights only affect the headlights. The dimmer control for the dash lights only affect the dash lights.
So if the parking lights are going off too, I would say its the headlight switch. Thats about the only thing that involves all three circuits.
It could also be the harness plug at the headlight switch.
BTW - the turn signal lights are another circuit from the parking lights.

Headlights will not come on automaticly at nite time.


There are 2 slider switches on the left side below the headlight switch. The vary bottom one must not be all the way to the left, gently slide it to the right. That should solve your problem.

I own a 1999 Buick Regal GSE with 94K miles. I recently noticed that my dashboard lights sometimes come on, and sometimes don't. Sometimes, during the day, if my dashboard lights are on, and I pull out...


In the 99 Regal, the headlamp switch is also the dimmer switch for the instrument cluster.
With the headlights on, try rotating the switch to bring up the "nighttime" intensity.
If the headlight switch has a pre-set dimming function for the instrument cluster lighting (in other words, not adjustible by rotating the knob), then
replacement of the headlight switch would be the only way to fix the instrument cluster lighting problem.
See Wiring Schematic below.

Hi, try disconnecting the connector from the headlight switch. If this doesn't turn the lights off, the problem is the body control module. If disconnecting the headlight switch DOES turn the lights orff, replace the headlight switch. You can probably get a used body control module from a salvage yard. They may also have the headlight switch, but you can get those at your local parts chain. To access the switch, pull the bezel straight out as shown below. The BCM is behind the fuse panel as shown below. Please let me know if you have any questions, anmd thanks for using FixYa.

Removal of head light assy 1989 ford ranger.


Hello,

To remove the front head light please follow the steps below:
  1. Place the Ford Ranger in "Park." Turn the engine off. Turn the headlights off. Remove the key from the ignition. Allow the truck to cool for about 20 minutes.
  2. Open the hood of the vehicle. Locate the two retainer pins on the headlight assembly of the light that needs to be replaced. Pry the retainer pins open with your finger. This releases the headlight assembly from the Ranger.
  3. Pull the headlight assembly forward. Unplug the electrical connector from the back of the assembly by hand. Rotate the retaining ring counterclockwise and slide it off the plastic bulb base.
  4. Pull the burned out bulb straight out of the headlight assembly. Discard the used bulb. Insert a replacement bulb into the headlight assembly and push it straight into the socket until it clicks into place. Slide the retaining ring around the bulb and rotate it clockwise to secure it.
  5. Plug the electrical connector into the back of the unit. Slide the headlight assembly back into the Ranger. Push the retaining pins back down to secure the headlight assembly.
Hope this helped. thank You for using FixYa!!!

My headlights come on but my taillights have just stop working.But when I press the brake they come on.What do I surpose to do?


Check your fuses first. In a '92 Roadmaster, they would be number 14 and 15, light blue 15A fuses. I am not sure about other years, but your owners manual should tell you. Otherwise it could be the headlight switch, or the Twilight Sentinel Module if your car has the option.
I had a similar problem a few months ago with my '92 Roadmaster Wagon. My problem was due to the Twilight Sentinel Module. If your parking lights do not come on (dash lights, too), but the headlights do when your Twilight Sentinel should turn them all on, try to use the rocker switch to turn on the lights. If the parking lights come on with the rocker switch, I believe you need a Twilight Sentinel Module. However, if you do not have a Twilight Sentinel Module, or your lights do not come on using the rocker switch, you may have a bad switch or faulty wiring. The Twilight Sentinel Module is located way up under the dash, to the right (passenger) side of the steering column where the column goes through the firewall. It looks like the one in the picture, and could be off white or gray, or perhaps a different color.
