DOES THE DIMMER SWITCH FOR DASH LIGHTS NOT WORKING HAVE ANY THING TO DO WITH TAIL LIGHTS AND PARKING LIGHTS NOT WORKING

STOP and PARK LPS will be tail lights.

ILLUM and GAUGES will.be dash lights.



STOP
Stop/CHMSL, Stoplamps

GAUGES
IP Cluster, DRL Relay, DRL Module, HDLP Switch, Keyless Entry Illumination, Low Coolant Module, CHIME Module, DRAB Module

PARK LPS
License Plate Lamp, Parking Lamps, Taillamps, Front Sidemarkers, Glove Box Ashtray

ILLUM
LP Cluster, HVAC Controls, RR HVAC Controls, IP Switches, Radio Illumination, Door Switch Illumination

Both are separate fuses, check them first. Dash lights are controlled threw the dimmer switch. Park lights threw the turn signal switch. If you have front marker lights, then the rear is a ground problem. Ground is at the body, in the back, on the drivers side. If no marker lights at all , replace the turn signal switch. If the fuse is good for the dash, replace the dimmer switch.

i assume you have checked all lighting fuses. if you have not, start there. do you have brake lights? if you do have brake and head lights then i would suspect the dimmer/light switch.

could be a in line fuseable link

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

No. Dash lights being out could be a bad headlight switch, since the dash lights are routed through the headlight switch, not the dimmer switch. Park and tail lights also controlled by the headlight switch.

All go out at once, first check fuses,then dimmer switch for dash lights, finally headlight switch. To check dimmer switch, pull connection off back, on harness with test light and headlight switch activated, 1 of the leads should have power, if so, use ohm meter on dimmer to make sure it has reading between 0 and some value, if no value, open, dimmer is bad, if there wasn't power then check headlight switch, there should be heavier gauge wire that powers switch and 1 for output to hi/lo switch, smaller gauge wires for tail lamps, dash lights, license plate lamps, parking lights. The color wires from dimmer would correspond to the same colored wires on headlamp switch, probe that connection on headlamp switch with switch engaged and see if you have power, if not replace switch, if so, check wire from switch to dimmer.Now if the lights slowly went from bright one day, to less bright some other day, to not working, then the bulbs are bad... good luck...

Are your "Park" lamps working on the outside of the car? If not, then you probably have a problem with your headlamp switch. If the park lamps are working, then the problem is most likely with the dash light dimmer switch.

How are your dash lights? Usually dash lights and tail lights are on one circuit. The dimmer switch is also connected to both circuits. If there is a short in the dimmer switch, then either tail lights or dimmer switch could have problems.

there is a relay for those as well in the fuse box test the fuses for those tail lights and if they dont have power then its the relay.
