My right front headlight does not work on high or low beam. Replaced the bulb and it still does not work. The left head light works fine on low and high. I noticed that the bulb out indicator comes on when ever I have head lights switched to low beam but goes off when I switch to high beam. Though out this switching routine the left head light fails to work. what could be my problem? I have heard the head light relay could be the problem. How could I trouble shoot? and where is the relay located. I have noticed over the last couple of years that I have had to replace the left headlight bulb a couple of times. thanks for any help. Driving with only one eye at night. JMSH
