They are turned on by the BCM !
Park, Tail, Marker and License Lamps
The park, tail, license, and marker lamps are turned ON when the headlamp switch is placed in either the HEAD or PARK lamp positions, or anytime the automatic light control (ALC) turns the headlamps ON. When the headlamp switch is placed in the park lamp or headlamp positions, ground from G202 is applied through the signal circuit to the BCM indicating the park lamp request. In response to this signal, the BCM applies ground through the park lamp relay control circuit energizing the PARK LP PCB Relay. With the relay energized, battery voltage is applied through the switch side of the relay, both park lamp fuses, and the supply voltage circuits illuminating the park, tail marker, and license lamps. Ground for the left front park and marker lamps is provided at G101 and the right front park and marker lamps at G100. Ground for all rear lamps is provided at G302.
Turn Signal Lamps
The LT T/SIG and RT T/SIG fuses located in the underhood fuse block supplies battery positive voltage to the body control module (BCM) for turn signal and hazard lamp operation. When the turn signal switch is place in either the LEFT or RIGHT position, ground from G202 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. The BCM also sends a message via GMLAN to the instrument panel cluster (IPC) to cycle the turn signal indicator ON and OFF depending on the position of the turn signal switch.
Ground for the turn signal lamps is supplied as follows:
G101 provides ground for the left front turn signal lamp
G100 provides ground for the right front turn signal lamp
G302 provides ground for the left and right rear turn signal lamps
flasher/blinker is busted. this is located under your dash board. remove steering column cover, turn on LEFT turn signal (yes, the one that is working), then you will hear a clicking sound. locate the relay that causes the sound. there you can see 2 relays (one for LEFT, other one for RIGHT turn),replace busted one.
The marker ("running") lights are a separate circuit than the signal lights.
Normally you have a tail light, and the front running lights on with the headlight.
The bulbs used in the rear signal lights would be a single filament 1156 bulb, whereas the bulbs in the front are dual filament, one for turn signal, one for running light.
The side marker light must be removed in order to get at the turn signal light.
There are two screws holding the side marker light which is situated above the turn signal.
Open the hood.
Remove the phillips head screw at the top of the side marker light.
Using a long #2 Phillips screwdriver, remove the screw on the outside of the side marker light. This can be seen by looking between the lower side of the side marker light and the top side of the turn signal.
The side marker can be moved.
The turn signal has one screw on the top of the fixture that must be removed.
Slide out the turn signal fixture. There is a small feature on the lower front corner of the turn signal fixture that you must note to properly reinstall the turn signal.
In order to get to the bulb, rotate the bulb socket 1/4 turn CW or CCW. The bulb socket is loose.
The bulb is simply pressed into the socket.
Not sure of the type, but it can be found at your locale auto parts store.
The bulb is used in several places on the 1994 GC, so get apacket with two, if possible.
Assembly in reverse. Be careful not to overtighten the screws as they are replaced.

Voltage is applied through the TURN fuse and the turn/hazard flasher when the ignition switch is in the following positions:
• BULB TEST
The voltage travels to the contact in the hazard switch. The hazard switch is located in the turn/hazard-headlamp switch assembly. This contact is normally closed.
When the left turn signal is turned on, voltage is applied to the following components.
• The left turn indicator
• The left front park/turn lamp circuit 14
• The left rear turn lamp circuit 18
The turn lamps turn on immediately. The current flow heats up the timing element. The timing element is located in the turn/hazard flasher. The timing element repeatedly opens and closes the circuit. This action causes the turn lamps to begin flashing.
The voltage that is applied to the left front park/turn lamp is also applied to the left front marker lamp. If the headlamp switch is in the OFF position, the left front marker lamp will find a path to ground through one of the following lamps. The following lamps provide low resistance paths to ground:
• The right front marker lamp
• The right turn indicator
• The right front park/turn lamps
• The left front park/turn lamps
The left front marker lamp flashes with the turn lamps. The voltage drop across the marker lamp is much higher than the voltage drop across the other lamps. The lamps that are used for the ground path will not flash.
When the headlamp switch is in either the PARK or HEAD positions, voltage is applied through the following components:
• The EXT LP fuse
• The marker lamps
• The park lamps
When the left turn signal is turned on, the left marker lamp will have voltage at both connections. The left marker lamp does not light. When the turn/hazard flasher stops the voltage to the turn lamps, the marker lamp is grounded through the turn lamp. The marker lamp does not go on. The left front marker lamp flashes in the following manner:
• The left front marker lamp flashes on when the turn filament of the left front park/turn lamp goes off.
• The left front marker lamp flashes off when the turn filament of the left front park/turn lamp goes on.
Voltage is applied to the right lamps in the same manner, when the right turn signal is turned on.
Voltage is applied at all times through the following components to the normally open contact of the hazard switch in the turn/hazard-headlamp switch assembly:
• The STOP HAZ fuse
• The turn/hazard flasher
When the hazard switch is turned on, voltage is applied to the following components:
• The front turn lamps
• The rear turn lamps
The following lamps flash on and off:
• All of the turn lamps
• Both of the turn indicators
The front marker lamps flash with the hazard lamps on, just as the front marker lamps flash when the turn lamps are on. If the headlamp switch is in the OFF position, the front marker lamps flash on when the hazard lamps are on. The front marker lights will flash on when the hazard lamps are on if the headlamp switch is in one of the following positions:
When the hazard lamps are on, the following conditions apply:
• The turn circuit is always open.
• The turn/hazard flasher controls the lamp.
Voltage is applied through the EXT LP fuse, to the headlamp switch at all times. Voltage is applied to the park lamps and the marker lamps when the headlamp switch is in the following positions:
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
Voltage is applied through the STOP HAZ fuse to the brake switch at all times. When the brake pedal is depressed, the brake switch closes. This action applies voltage through the turn/hazard-headlamp switch assembly to the following lamps:
• The high mounted stop lamp assembly
• The left tail/stop-turn lamps
• The right tail/stop-turn lamps

Turn the engine off and approach the side of the porsch with the burn-out side-marker light. If you are replacing both, start at either side; the replacement procedure is the same.
Remove the screws from the plastic fender liner. Peel back the liner to access the area behind the fender.
Reach your hand inside to gain access to the side-marker
light's backing. Push the backing forward to release the side-marker
lens; it's held in place by small clips.
Grab the lens on the outer side and turn it over to access the back. Gently turn the bulb to release it from the plastic lens.
Pull the bulb straight out to remove it from the electrical
socket. Insert a new bulb, but do not touch the glass part of the bulb
with your hand.
Push the new bulb into the side-marker lens. Turn it
clockwise to install it. Push the side-marker lens back into place.
Apply gentle pressure to the lens to pop it back into its mount.
Replace the screws along the edge of the fender liner.
The bulbs on these cars can be delicate. Some get replaced every year or so-( headlights, tail and brake) and some I've never touched in 8 years (my front turn signals and marker lights)
The fast blinking occurance is normal when a turn signal bulb goes out.
The rear lights are common to blow, I keep spares in the glovebox.
Make sure you were given the correct bulb, check to see that it works and isn't defective. Also there is an empty spot in the rear bulb holder- make sure you didn't mistakenly pop a bulb in there cause' it won't work.
The front right signal light is in the right headlight housing. Open the hood and on the back of the housing there are two plastic caps. One is curved and one is rectangular- you want to take off the rectangular one.
Open the drivers door and on the side of the dash there's a cover. This is the main fuse block. Use a coin or carefully with a screwdriver pry it open. To check a fuse pull it out, noting exactly where it came from, and visually inspect it to see if it is blown.

The turn signal flasher is integrated into the hazzard button in the center of the dash. If all else is good and you suspect the flasher is bad, which is a good possibility, call a VW dealer and have them run your VIN# to check for recalls. The hazzard switch for some cars around your year had a recall on em'.
