'91 Nissan Maxima, No High Beams
The low beams work fine on my '91 Nissan Maxima. The problem
is, there are no high beam lights both sides. The headlights go out when
the high beams are activated.
Do not make any assumptions that the high beam part of your headlight
system has a problem until you've replaced at least one or both of the
headlight bulbs or have used a test light to confirm that there is no
electrical power to the high beam headlights. Many times, people do not
realize that one of their high beam lights are out during normal driving.
Once the other bulb fails there are no high beam lights and people think
there is an electrical problem. If there is no electrical power to or
for the high beam lights on your vehicle then the dimmer switch is worth
