'91 Nissan Maxima, No High Beams

Q: 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.

- Walt

A: 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 inspecting.
