Please describe the old light fixture and the new light fixture. If the new light fixture is fluorescent, then using a dimmer with it won't work and is a fire hazard - unless you have a specially designed ballast which is designed to be used with a standard dimmer. If that is what you have, then the ballast in your new fixture is bad.

Interior Lamps Dimming
The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
• Power window switches
• HVAC control head assembly
• Radio
• The instrument panel cluster (IPC)
When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

I would have it checked for DTC'S - diagnostic trouble codes stored in the BCM !
DTC B2624 Display Dimming Input Range/Performance
The body control module (BCM) supplies voltage to the instrument panel dimmer switch through the instrument panel dimmer switch signal circuit. The dimmer switch varies the voltage and returns the new voltage to the BCM through the dimmer switch signal return circuit. The BCM uses this voltage to determine the illumination level of the instrument panel lamps.

DTC B2625 Display Dimming Pulse Width Modulation (PWM) Output Circuit Range/Performance
The body control module (BCM) receives a variable voltage from the instrument panel (I/P) lamp dimmer switch. The BCM uses this signal in order to vary the illumination level of the I/P lamps. The I/P dimming lamps output from the BCM is a pulse width modulated voltage supply used to light the I/P lamps. If a malfunction occurs in the I/P dimming lamps output circuit, this DTC is set.

DTC B2662 Park Lamp Switch Circuit Malfunction
The park lamps are controlled by the turn/headlamp switch. Positive battery voltage is supplied to the switch through the EXT LP fuse. When the turn/headlamp switch is placed in the park or head position, battery voltage is supplied to the park lamps. The body control module (BCM) is also connected to the park lamp circuit to sense whether or not the park lamps turn ON when the low beam or high beam headlamps are turned ON. The BCM also uses the parklamp battery positive voltage to power the instrument panel (I/P) dimmer output circuit. If the BCM senses that the low beam or high beam headlamps are ON and the park lamp input is not active, DTC B2662 sets.
Do the park lamps work ?

Dashboard lights will go out randomly. It has done it for short periods before but it did it for 200 miles on hwy in dark.


The sensor is usually located on the top of your dashboard. You might see it if you look into your vehicle through your windshield at your dash.
I have seen( one time ) that a gps was bright enough that it caused the dash lights not to come on because the sensor thought it was light outside.
Or you could have gotten a bad sensor.

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

I have a dimmer switch that is backlit. The switch itself is flickering - havent noticed this before. The lights still work and the dimmer on the side of it works also. Should I be concerned


Hello.
Had this problem my self a while back, here's what I found out. Firstly, it may simply be the switch is faulty. If this was a new install, take it back and try another. But before that, get all relevant information about the lights you are dimming. Here's why: Some light fixtures are incompatible with dimmers. They may dim - but not properly. Some lights/fixtures require specific dimmers to be used: incandescent or not, total wattage in fixture, and so on. Having this information may save you a trip if it's actually not the switch. Good luck.

3 way dimmer turns on and off, but does not dim


All your wiring looks good. Many times dimmer just have problems and are faulty. You should note that the dimmer can only handle 600 watts. If you have that or more on it, than you have probably fried the dimming mechanism. In either case the dimming mechanism is not working properly and you will have to take it back and get the same dimmer or a different one. Tell the store they sold you a faulty dimmer and you can get a replacement at no cost.

In general practice, you can only install ONE 3-way dimmer switch to control the lights. If you use two regular 3-way dimmer switches, the circuit won't work.

However, newer technology allows for double 3-way dimming from different locations. See this article about how to do this:

Installed 3 way dimmer - when turning off at 2nd location can not control dimming from first location until second location has been turned off then able to control dimming at first location - pass &...


Some dimmers are specific to which end of the 3-way system they are installed on "Power" or "Switch Leg". The way you can test which side is the power and switch leg is to test the wire on the "Black" screw of the switch (common) to ground with the lights OFF. If you have power on the "common" screw with the lights OFF it's the power end, if you have no power on the "common" screw with the lights OFF it's the switch leg end. Verify that you have the dimmer on the side specified in the instructions (switch leg). Sounds to me like you have it on the "Power End" so you are dimming on of the travelers instead of the light. That is why it is dimmed in one position and not in the other. (See page N-23)

Leviton slide dimmer switch w/locator light light comes on but doesnt dim


What sort of light is it , dimmer switches normally only work on Incandescent type lights not flourescent type.

Otherwise it sounds as if the dimmer function is faulty.
