The headlight switch that has the dash light dimmer knob. The dimmer switch went bad and you can only fix it by getting another headlight switch on most cars. Some though have a separate dimmer switch.
the dimmer should have a rating on it in Watts. dimmers are not suitable for low energy lamps though
possibly a bad headlight switch, or dimmer switch. Some later model buicks have a lighting module under the dash about in the middle. I think yours is too old to have that though.
make sure your dimmer switch isn't turned all the way down. Then check the fuses next.
Check first and make sure that someone didn't mess with your dimmer switch. If it's okay, you probably have a bad ground in the instrument cluster.
check the brake light switch above the brake pedal
The brake lights are a separate circuit from the other lights. Check the fuses and bulbs. If fuses and bulbs are okay I would suspect the brake light switch is at fault.
Though this theoretically could work on a very few power tools, it is NOT a good idea and most likely doing it will only wreck the tool (or the dimmer switch). And why would you want to lower the voltage anyway?
i know im a girl and im only 14 and all but there is a light level sensor built into the LCM which will make the dashboard lights dimmer in high quantities of light and make them brighter in the dark. there is a little dot just above your light switch knob which is the sensor. i don't actually think you can adjust them though
I'm going to assume that the switch that's getting warm is the dimmer. Even when a dimmer is working correctly it gets warm and that's just the electronic parts of it. The face of a dimmer is actually a heat sink to help remove excess heat. If you swap out the dimmer you will likely find your problem is resolved. Remember to de-energize the circuit by turning off the breaker before working on it. If in any doubt, consult a qualified electrician. Andy Be aware that a dimmer for lights does NOT work for fans (though it may sometimes appear to work, you can end up with noise, problems such as the light attached to the fan not working, the dimmer getting overheated, etc). So even though it might seem to work at first, you'll have problems, and it's against code to put the wrong kind of dimmer there. You can purchase a dimmer which is rated for ceiling fans at Home Depot or Lowes, but they are more expensive than light switch dimmers. Of course, if there is a single on/off switch at the wall which controls the fan and its light, then you might be better off buying a remote control unit to install in the fan - it will allow you to dim the fan and light separately (and safely). Or purchase a new fan with a remote... ceiling fans are cheap enough now that if yours is old enough, it might be a nice time for an update.
You probably have a faulty headlight switch. Replace it and that should fix it. Been there, done that.
The headlight switch may be bad. Try replacing. Its the Headlight switch. The switch has a built in Circuit Breaker that self resets. It has become bad and will eventually give it up.
