2003 Kia Sedona no parking lights at all, also no dash lights

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

Is it only the gauges or the all the instruments and heater controls? The first place I'd look at will be the dimmer switch. Normally the instrument lighting shares the same circuit as the parking/valet lights.

A service manual will provide a series of tests that may help troubleshooting steps. But, since this sounds intermittent then it may be a connection problem. Try a visual inspection looking for loose connections.

Hello, what scan tool do you use? You can try some Auto Diagnostic Tools at Chinasinoy. I have ever bought one there.

Daytime running lamps control module. Fuse #37 - inside the passenger compartment or under hood fuse box ? Do you know how to use a volt meter an wiring diagram to find electrical problems ? You have a direct short to ground or fuse #37 wouldn't blow. Underhood fuse box fuse # 37 is for the park lamps .Supply's B+ voltage to the daytime running lamps module an the headlamp switch plus 37
PARK LP Fuse
20A
Headlamp Switch, Body Control Module (BCM), and Vehicle Interface Unit (VIU)...
Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned ON when the headlamp switch is placed in either the PARK or HEADLAMP position, or anytime the headlights are requested. The PARK LP fuse in the underhood accessory wiring junction block. When the headlamp switch is placed in the PARK position, battery positive voltage is applied to the park lamp circuit. The parklamp circuit then applies battery positive voltage to the DRL control module and to all the marker, park and tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302 The inadvertent power control feature prevents the park lights from remaining on more than 10 minutes if left ON. If the park lights are turned ON after the ignition switch has been turned OFF, or is in the ACCY position, they will remain ON until turned OFF or the battery runs dead.

Finding The Source Of Electrical Shorts In Your Car

Did You Checked up the Lamp itself ?

makes no sense to me

You will need to check the brake fluid level. I had the same problem and it drove me crazy for a while. I believe this occurs because of where the sensor is located, as you turn, the fluid will shift to the opposite side causing the sensor to think that it is low in brake fluid. Solution: Just top off.

I'm afraid to say it is most likely the circuit board shorting out
but may be trace the earth point to the chassis. It's often a bad ground that causes faults.
After this - check bulbs and finally the cable run back to the switch.
