If you are familiar with the gears going bad here is a free fix that worked for me
I handcranked the headlight up
took off the 10mm nut holding the arm to the motor ( you gotta take the top cover and black side cover off )
hand cranked the motor until the shaft rotated 180 degrees
re-attached the arm
hand cranked the light back down
no vid , no pics , just good info here.....
Then hit the headlight switch....works good as new
WHY ?
the motor uses only 1/2 the
gear
so....you get 1 freebie fix.....
if it happens
again....brass gear time.....
worst case , it gets you by for awhile until you can repair it correctly
ps....be careful out there...a lotta blue vettes have been crashing lately
