Why would the electric door locks on a 1987 Chevy Astro van be active but will not engage or disengage?
read up on how the thing works, and go from there.. Everyone
should have a manual for their vehicle, and the local library
should have a professional shop manual available to make copies of
for FREE...make the time to take time to read up on your vehicle,
and work like the PRO'S! Good luck :) Dave
