I have no dash lights or tail lights but no fuses are bad brake lights and headlights work !

SOURCE: left blinker light stays on solid when headlights are on

I have had this happen and it is rare, but I have had a filiment burn out in a two filment buld and short to the other filiment. It does happen and I think this might be your problem, the only way to find it is a visual inspection of each bulb. I am sure many people will think this is crazy, but I have had the exact same problem, I had the schematics, tested the circuits,etc. and them by accident found a stop/blinker 1157 bulb that had done this exact thing. I hope this helps you, check the bulbs in your headlights also.

the relays are usually adjacent to the fuses or on rear of fuse panel relays are different coloured as to what they control and are small square boxes which have flat terminals on one side for plug into a preset circuit if you have h/book it will give the info you req or tel dealer spares dept and enquire cost//colour// location? this is a simple diy hope this helps you? ps you do not mention if license plate lights are working as these are on rear light s same circuit

sounds like a broken wire in the harness. look around the bumper area,sometimes along the frame. may have to peel back some tape covering. also if you have a trailer harness look closely at those.

Before going ahead and spending money on a new module, test it first. The module is located under the steering column. You'll find a Brown wire on one of the connectors (i just looked at a wire diagram). Do no disconnect anything. Back probe the brown wire, which is the power feed to your park lights. With the lights off, there should be 0 volts on you voltmeter. Turn the park lamps on, There should be 12V. If there is not 12V, disconnect the connector and try to check voltage at the pin that feeds to the brown wire, if still not 12V, replace the module. If you do get 12V, then module is ok, find where the 12v is being dropped before making it to the lamps.

you have to check all fuses with a test light both fuse boxes under hood and under dash... if good next to look for is the light switch itself... has any radio work been done to the lately... if so alot of times hooked up wrong will blow park fuse as one of the wires to radio is the park voltage to tell radio to dim down some
