How to troubleshoot

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

Turn the parking lamps or headlamps on in order to illuminate the instrument panel and instrument panel cluster lamps. Voltage applies at all times through the TAIL fuse to the tail relay. Turning the turn signal/headlamp switch to the PARK or the HEAD position provides a ground path to the coil side of the relay to G202. The ground path energizes the coil of the relay. This closes the contacts in the relay. The closed contacts apply voltage to the IP dimmer illumination controller and all the illumination lamps. The illumination lamps are ground through the illumination controller. The controller is located on the left side of the instrument panel. Since the illumination controller is ground to G200, the lamps illuminate when voltage applies. The intensity of the instrument panel and the instrument panel cluster lamps is adjusted by the controller (4). The controller controls the intensity of the lamps by controlling the amount of current from the lamps to ground.Check the tail relay !

Just check every fuse with voltmeter, test lamp, or remove one at a time and inspect until you find blown fuse.

Check 20Amp LP Park Fuse in Underhood Fuse Block (mounted to right strut tower) Check 15Amp Tail Lic. Lamp Fuse In IP Fuse Block.

you blew a fuse. check fuses in both fuse boxes..
ahh yes, the IP cluster lamps are dad, but not the idiot warning lights
only the parking lights in the cluster are dead. right.?
and the park-tail, running lights and dash dim lights are all the same.
my guess three is a short on the TAIL fuse, the TAIL fuse blew
and took out: park-tail, running lights and dash dim lights are all the same.
it blew. most are marked tail even thought it runs side lamps and front parking lamps... TAIL is wrong, they are parking. lamps it truth.

There are a total of six fuses that control exterior lights and dash lights. Check all of these Fuses: 10, 21, 3, 7, 13, 33
Does the high mount stop light work when you apply the brakes?

Your instrument cluster and console lights are protected by fuse #2 (15 Amp) in the underhood fuse and relay box. They actually get power from the tail lamp relay. If the tail lamps are working, the relay and the fuse is not your problem. The brightness of these lights are controlled by the Multiplex Control Unit and theCPU built into the instrument gauge cluster. The dimmer circuits are actually integral with the instrument cluster. If the tail lights are working and the lighting in the instrument cluster is working, then the problem is either a CPU failure in the instrument cluster or an open circuit between the instrument cluster and the center console lights. The console lights themselves should have power all the time that the tail lights are turned on. The CPU in the instrument cluster provides ground for them to function. The wiring is a little different depending on which model you have and how it is equipped (LX, DX, EX, LX with side curtain airbags, etc.) however, the function is the same.

I highly recommend scanning your computer network for fault codes before spending a lot of time trying to perform electrical diagnosis. There may be a fault code present that will lead directly to the cause.

if its not the fuse then you have a bad headlight switch

the fuse for the tail lamp/instrument cluster may be bad.
