Power Door Locks

[mikester]

Question, are the grounds for power door lock actuators behind the kick panels on both sides ?
Not sure what the heck happened but all of a sudden the door locks stopped working on both doors. I pulled the panels off when I recently changed the uppers. Now they stopped working. Im assuming the connectors can go on only one way. I can hear the actuators clicking. What the heck ?

They ground thru the door lock relay. The only ground noted in my books is the direct relay body to the car body where it's bolted on.

Well, thats not good. Connector goes on only one way right ? What the heck could have happened ? They worked before.

Possible corrosion on the switch's terminal studs or the flat connector may have an issue with the cripped on terminals.

Both switches and the actuators are brand new. It never ends. 😕
