Hi,

since yesterday I cannot lock the doors of my 1998 F-150, except with the key.

It doesn't work with driver side or passenger side switch and it doesn't work with remote.

Unlock works.

Who has an idea?

Regards
Mark

 

If it involves the door locks on these trucks, always check the actuators.

 

I guess they are okay.
Otherwise both actuators failed in the same moment.
