Caterpillar 924F has no power to all four front facing work lamps, the switch is working OK, power in and out.

check that there is power to the relay from the switch or replace the head light module.

have you started with the basics check the fuses the head lights and the parking lights are different fuses

Four way flashers and turn signals are typically on the same circuit. If this is the case than no the turn signals would not work since the turn signal switch has been bypassed by the four way flasher.

I wiring diagram for this model would confirm whether or not it was wired in the above fashion.

hi,
That sound may from the color wheel. Open the angine, open block front of lamp.


open cover of color wheel and grap it.

Rotate color wheel manualy , listen it. If hear fristing sound, means color wheel is bad. Replace it too.
Good luck.

Problems with the DM assembly will cause perpetual "boot up" or blinking sequence, but if this is the case the TV never actually turns on. If you are able to turn power on after boot-up (which should only occur at plug in), then suspect lamp or ballast errors. The lamp is simple to inspect yourself, just don't touch the face of the bulb. If that's ok, you'll need a qualified service tech.

Try the hazard lights to check if all four lights flash, if not then check the bulbs. If the bulbs are ok check the contacts and the connections. if all all these are ok the problem could be the indicator switch. The flasher unit is fitted in the circuit before the indicator switch, that is why it operated although the lights might not.

Fog lamps are installed on the front bumper. The switch is located to the left of the steering column on the dash panel. The fog lamps are turned off by the circuit relay when the high beam driving lamps are turned on. The circuit relay is located on the right front wheelhouse panel near the blower motor.

Good luck, and remember rated this help.
Removal & InstallationFog Lamp Element
See Figure 1

Fig. 1: Exploded view of a fog lamp assembly

1. Remove the lamp stone shields, the four bezel attaching screws, and the bezel.
2. Remove the reflector assembly from the lamp body.
3. Remove the bulb holder from the assembly. Remove the element from the bulb.

DO NOT handle elements with your bare hands, always handle with a clean cloth. Oil from your hands will cause the element to fail.

1. Installation is the reverse of removal.

Fog Lamp Switch
The fog lamp switch is removed and installed by simply prying the switch from the instrument panel and unplugging the electrical connector.
FOGLAMP BEAM ADJUSTMENT

1. Position the vehicle on a level surface, facing a wall approximately 25 feet away. Remove the lamp stone shields and loosen the adjustment nuts.
2. Turn the fog lamps ON and adjust as follows:
   1. Distance between the light beam centers should be equal to the distance between the lamp assemblies on the bumper.
   2. Height of the light beams on the wall should be 4 inches less than the center of the lamp assemblies when mounted on the bumper.
      
3. Install all previously removed items after turning OFF the fog lamps.
