I'm having a problem with the power door locking system on my 2011 Toyota Highlander.
To put it simply: Un-locking the doors with the power lock system works fine, but locking the doors with the power lock system doesn't work.
Details:
The usual actions that would trigger the doors to un-lock are working correctly:
- Shifting into Park
- Pressing the Unlock rocker switch on the driver's door
- Clicking the Unlock button on the remote fob (twice)
Each of these actions causes all 4 doors to unlock. So un-locking is normal.
However, the corresponding actions that should cause the doors to lock, do not work.
- Shifting out of Park
- Pressing the Lock rocker switch on the driver's door
- Clicking the Lock button on a remote fob
Currently, none of those actions cause the doors to lock.
One other related piece of information: Locking the doors with the remote fob would ordinarily produce a single beep from the alarm system, if everything were working normally. Currently, I do not hear a beep when I push the Lock button on the fob. This makes sense, since the doors are not locking.
BUT, if I manually lock each of the 4 doors from the inside (i.e., flip the locks one by one on the doors), and then click the Lock button on the fob, I do hear the single beep.
Any advice on how I can troubleshoot this further?
