    Does the dimmer also dim the Clock??? That is pretty dim now and I have noticed it has always been dim with the Headlights on....

  • woodfurd Jul 16, 2009

    THE DIMMER IS THE CONTROL U USE TO DIM THE DASH LIGHTING AT NIGHT



    U mUst Think I'm a Moron to tell me Something like that-----I'll dispute the charge with my C.C. Company-----You have been WORTHLESS.......

  • woodfurd Jul 16, 2009

    Maybe tomorrow I'l call you, To tell me what the Dimmer does was insulting.....

    And what wire is # 3 on the harness I assume you are talking about?? The harness into the Dash panel hase many wires and I don't think the problem is there.....



    I got no where close to the dimmer slide switch that operates the Dash panel lights-------I'm this far Into it I guess my next step is to pull the F'n Dimmer switch out......More screws and panels to remove.....



    FYI: I fixed the Intermintent wiper controle-----I put a glob of solder on the break in the burnt trace on the board.....



    This is not even my SUV-------Just trying to help a friend out who is going thru Forcloser.......

  • woodfurd Jul 17, 2009

    I was just hoping I didn't have to pull the dash apart more to get to the Dimmer switch. If you know so much about the Dimmer switch, What is the best way to remove it or test it Without removing it??

    As far as I can see I must Remove the Steering Colim shroud and go from there....What size driver do I need for the Screws holding the Colum shroud together ?? I already have the 1 Torx dirve out......



    You will impress me if you can answer these ?'s........

I would double check the fuses before you do anything else. If you have a multimeter, you should check across the fuse terminals for continuity. Sometimes a fuse can go bad, but you can't see the break inside of it. If they all seem good, you can pick up a repair manual for the Jeep, as it will have the wiring diagrams, along with wiring color codes in it for the dash lights. These manuals can be purchased at most auto parts stores for, around $20. A cheap multimeter, or a 12 volt test light can be used to trace out the wiring.
With the manual, and a test light, or meter, you can start checking voltage at the fuse block, and work your way towards the dash lights.

Make sure the connector at the3 back of the dash is fully inserted and locked, this is a common mistake, check to see if dash light feed has 12 volts when light are turned to brightest setting, also test the dimmer with a test lite.

    IT SHOULD DIM ALL DASH LIGHTS

  • yadayada
    yadayada Jul 16, 2009

    THE DIMMER IS THE CONTROL U USE TO DIM THE DASH LIGHTING AT NIGHT, YOU NEED TO PULL THAT OUT AND TEST IT (WITH IT CONNECTED), IT SHOULD HAVE 12 VOLTS INTO IT AND WITH A TEST LIGHT YOU SHOULD SEE THAT TEST LIGHT DIM AND BRIGHTEN WHEN YOU OPERATE THE DIMMER FROM THE BRIGHT TO DIM SETTING ON THE OUTPUT SIDE.

06 Malibu LT Dash lights shut off


hi, gm vech. are elec.complex with logic that is all there own. im a retired ford tech, and gm would drive me crazy sometimes. now some ideas, your dash light are controlled with an ecm, keep in mind, your dashlights and tail lights are on the same circut. i would check your batt. cables, if your ground cable has a high resistance it could cause issues. in fords they had bad dimmer switches that would cause the same issue. if you have someone with an obd2scanner it might have a code.hope that helps.

Head lights, tail lights and dash lights won't come on.replaced head light switch but didn't resolve problem


Not the turn signal switch if the dash is out also. Check the fuse for the dash/illumination first. If good, then you have a power or ground problem to the switch. If bad and they come on, replace the turn signal switch.

How do I test the dimmer switch on my 1987 chevy chevrolet nova? And if it's broken, how do I replace it? Asking because my dashboard lights don't come on even though all the fuses seem to be...


Dash lights are routed and controlled by the headlight switch. Dimmer switch should not affect the dash lights. You cannot test either switch, but if not working right, just try a replacement.

I have a 98 chevy malibu. the tail lights, running lights and instrument lights do not work but head lights do


The good news is that all of these problems stem from the same source: the 15A PARK LPS fuse in the underhood wiring harness junction block. When you set the turn/headlamp/wiper switch to PARK, the park lamp relay in the junction block closes and power is applied to the front marker lamps and the park filament of the front park/turn lamps as well as the tail filaments of the rear tail/stop lamps.

As for the instrument lights, that same PARK LPS fuse applies power to the same turn/headlamp/wiper switch that, when set to PARK or HEAD applies power to the variable panel dimmer switch which lets you set the illumination level. Switch output is applied to the lamp dimmer module and module output passes through the 10A INST LAMPS fuse in the right I/P wiring harness junction block to the instrument lamps

I have a 1988 ford thunderbird 5.0 auto trans the electronic instrument panel cluster has gone dim can hardly see panel all fuses are good has auto dim head lamps


Usually a problem with the mini-lights inside the cluster, the circuit board or the dash light dimmer switch.
You can take the cluster out and see if the bulbs can be replaced or check the dimmer.
Not connected to automatic dimmer headlights.

Dash lights go off intermittently


I'm no expert, I recently purchased a 2003 vibe. I noticed the automatic headlight's sensors can be super-sensitive, about an hour hours before dusk they'll kick my headlights on (when the sun is still shining!), or sometimes when I go into an underpass, and then sometimes they'll realize it's light enough and turn themselves off. This would cause your dash lights to go to the 'headlights on' mode and turn the headlamp signal on, the intensity is controlled by the dimmer/dome light control on the left side of the dash. Check to see if the dimmer is down too far, as this could cause the lights to dim when the automatic headlights turn on. It's also possible that the dimmer is not working, thus no power is getting to the dash lights through the dimmer. Try testing it by starting the car in daylight, then manually turn on the headlights, then adjust the dimmer. Like I say, I'm no expert, just guessing because I've noticed it happen similarly on my Vibe, but my dimmer was at half-way, as I like it for night driving. Someday, I'd like to disable the automatic sensors and DRL.

Dash lights go off when head lights are turned on.


Your car is perfectly fine. Your dash dimmer is turned all the way down. Your dash dimmer automatically turns on with your headlights. You need to locate your dash dimmer and turn it up.( will be easy to locate with owners manual).
