1987 W124 vacuum lock question
My vacuum lock system was a compromised from the leak into the passenger side foot well. I got a new pump that I have verified works in both push and pull. When I connect it directly to the battery (the power to it has a short somewhere) and then use any of the door or trunk locks the pump kicks on and locks all the doors, trunk, and gas door. However when I unlock at any of the doors or truck nothing happens?
Any ideas?
Thanks,
Geoff
