Hi Angela, look behind the headlamps and you will see a cog like wheel with a small bolt in the middle (below the headlamp harness). use a small ratchet or spanner to turn the whell left or right for up and down to lift or lower the headlamp.Place you vehicle facing something that is white and turning the bolt slowly you will note the headlamp moving up or down. Hope this is helpfull info as that is how i sorted mine out.

GENERATOR OUTPUT LINE VOLTAGE DROP TEST
This test determines the condition of the wiring from the generator "B" terminal to the battery (+) terminal (including the fusible link).
1.
Be sure to check the following before testing:
a.
Generator installation and wiring connections
b.
Generator drive belt tension
c.
Fusible link
d.
Abnormal noises from the generator while the engine is running.
2.
Turn the ignition switch to the OFF position.
3.
Disconnect the negative battery cable.
4.
Disconnect the generator output wire from the generator "B" terminal. Connect a DC test ammeter with a range of 0-100A in series between the "B" terminal and the disconnected output wire. (Connect the (+) lead of the ammeter to the "B" terminal. Connect the (-) lead of the ammeter to the disconnected output wire.)
An inductive-type ammeter which enables measurements to be taken without disconnecting the generator output wire is recommended. Using this equipment will lessen the possibility of a voltage drop caused by a loose "B" terminal connection.
5.
Connect a digital-type voltmeter between the generator "B" terminal and the battery (+) terminal. (Connect the (+) lead of the voltmeter to the "B" terminal. Connect the (-) lead of the voltmeter to the battery (+) cable.)
6.
Reconnect the negative battery cable.
7.
Connect a tachometer or the scan tool.
8.
Start the engine.
9.
With the engine running at approx. 2500 rpm, turn the headlights and other lights on and off to adjust the generator load on the ammeter slightly above 30A.
Limit: max. 0.3V
When the generator output is high and the value displayed on the ammeter does not decrease to 30A, set the value to 40A. Read the value displayed on the voltmeter. In this case the limit becomes max. 0.4V.
10.
If the value displayed on the voltmeter is still above the limit, a fault in the generator output wire may exist. Check the wiring between the generator "B" terminal and the battery (+) terminal (including fusible link). If a terminal is not sufficiently tight or if the harness has become discolored due to overheating, repair, then test again.
11.
After the test, run the engine at idle.
12.
Turn off all lights and turn the ignition switch to the OFF position.
13.
Disconnect the tachometer or the scan tool.
14.
Disconnect the negative battery cable.
15.
Disconnect the ammeter and voltmeter.
16.
Connect the generator output wire to the generator "B" terminal.
17.
Connect the negative battery cable.

Answer
1. Remove the dust cover from behind the bulb that needs replacement.
2. Unplug the bulb.
3. Taking note of the bulb orientation, unhook the bulb retaining clip from the tang that holds it in place.
4. Remove the bulb.
5. Install the new bulb in the same orientation and clip in place.
6. Reconnect the electrical connector to the bulb.
7. Reinstall the dust cover.
Alternatively, if the bulb is burned out and you have less than 60,000 miles, you should take the car to the dealer and let them do it for free for you.
