I have a weird case of an Aussie Falcon 4.0 GLI misbehaving when you lock the doors from any point(power switch,HF remote and pressing the lock) all the locks cycle up and down in some cases up to 11times before locking...have swopped and replaced the actuators to no avail ...any ideas???

 

Maybe check that the power source isn't improperly plugged into the wrong wires (if it's an aftermarket type). If it's original - use a tester and check the lead in wire for a good connection and double-check your grounds. If the power's coming in weird the whole thing will of course act weird. Last (NOT least) (and again) - take off check and clean the battery cables (where the connect to the battery-of course).

 

yea thats the same problem I am having but a little different.. what mine is doing is if you lock it from the drivers side it does go up and down non stop and it will not lock. yet when I do it to the passenger side it will lock straight awaywithout fail.. any reason to why it does that???
