Dash lights goes out when head lights come on

No. It has auto lamps.all newer vehicles have them. Some you can turn off. You have to have the light switch in the dash. If it is in the turn signal switch/ column. Your out of luck.

It's not the switch that is the sole control for the Auto-On. You need the switch, plus the light sensor that goes in the top of the dash and the control circuit which is part of the climate control. Changing the switch will not give you auto-on.

head light switch has a fault. would need to be replaced if you want the dash lights to work. there is a resister on the switch so you can control the brightness of the dash lights it must of faild.

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: diyobd2.fr

ACDelco - Switch, Headlamp & Instrument Panel Lamp Dimmer Part # F1538 at oreilly auto parts or try any auto parts store

could the sensor be bad, dirty or have something sitting on it? I had this happen to me.

thier is problem with brake switch on master cylendre leaks brake fluid on top a abs madule and short the wires need to change switch, plug ,and abs madule

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

This sounds to me like you may have a faulty headlight switch. If the switch is on the steering column, you will need to replace the whole multi-function switch assembly, if it is on your dash panel, you should be able to just replace the actual headlight switch. Hope this helps.

WHAT YOU MIGHT CHECK IS THE FUSE FOR TAILLIGHTS, OR DASH LIGHTS. THEY WORK OFF THE SAME FUSE. IF THE FUSE IS BLOWN THE HEADLIGHTS WORK BUT NO TAIL OR DASH LIGHTS
