High beams work but low beams don't

8 Answers


There is a high beam element and a low beam element in the light bulb both low beam elements could be bad.


thats right.. also high/low flash/light switches


I changed the bulbs on both sides and its still doesnt have low beams

ive been looking at this for you..start at work sheet 1. >http://www.autoshop101.com/forms/maz-ewd.pdf


Next step check fuses may be separate fuses for high beam and low beam.


there are 2 fuses...did you check the socket at the headlight for 12 volts with a test light.to make sure it not a ground problem.
