I've reviewed the WIS for your car and so far have determined the following.
1. Fuse 35 has nothing to do with the problem.
2. The left parking lights located in the left front directional assembly and the parking light inside the left headlight assembly are fed by the fuse #3.
3a. The right parking lights located in the right front directional assembly and the parking light inside the right headlight assembly are fed by fuse #4.
3b. Both fuses #3 and #4 are fed by the light switch.
3c. For the parking lights, the light switch is fed by either the +30 or +X +12VDC nets. I would not be suspicious of either of these nets because they effect many other things like actual running of the car.
4. TWICE is a destination for the +12VDC provided for the front parking lights....NOT THE SOURCE OF +12VDC. The common source for the +12VDC for the front parking lights is the light switch itself. I would not be suspicious of the TWICE.
5. Check #1: Fuses 3 and 4 in the panel by the drivers door. Fuse #3 is in the circuit for the left parking lights. Fuse #4 is for the right.
5. Check #2: Using a voltmeter, check for +12VDC at the left or right parking light. On the left the wire going into the socket will be green for either left parking bulb socket. On the right the wire will be blue. The other side of your meter should be connected to the negative post on your battery or the car ground.
6. Check #3: Using a voltmeter, check for +12VDC at fuses #3 and #4. If you have a pin-type lead on the voltmeter you can do this through the top of the fuses without removing them.
Note that all checks should be made with the ignition switch in the running position.
Now, what to do with all of the information you have. I suggest reading this through to find the scenario that applies.
1. If you have +12VDC at both sides of fuses #3 and #4....both fuses are OK and the light switch is OK.
2. If you do not have +12VDC at both sides of fuses #3 and #4....the light switch might be the cause.
3. If you have +12VDC on only one side of fuses #3 and #4, the fuses themselves are open, or burnt out.
4. If the parking lights inside of the directional assemblies work but the little parking bulbs inside of the headlights do not, suspect the bulbs themselves. These bulbs burn out 10 times more frequently then the others.
5. If you detect +12VDC at the left and right parking lights, then the bulbs themselves are suspect.
Final thoughts: Fuses and bulbs generally don't fail in pairs. The only exception to this might be the parking bulbs inside of the headlights; these don't have a long life, so it is possible for both to have failed at different times and you never noticed.
Let us know what you eventually find. If you want some off-BB help, send me an email with contact info.
