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 would have to check and see if you are getting any power out of the light switch. There is a seperate wire for the headlights and the dash lights.

Fuse is probably blown out. Replace fuses for respective functions. Find the fuse box: might be in engine near battery or below steering wheel. open top and check for blown fuses. Try replacing if blown fuses are found. If all fuses are OK then it is very unlikely that all the bulbs are blown.

Have you looked under the hood? There are more fuses under the hood. Is your dimmer turned down on your dash lights?

You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.
