Lately (within the last 4 months) the power locks are acting weird. It always happens after I go through the car wash, and the outside temperature is cold (today's low was about 15 degrees F). Some info:
- The first clue that something is weird is that the lock/unlock button on the dash does not light up (when the doors automatically lock at about 15mph).
- Other symptoms include the rear hatch not unlocking with the hatch button (works only with the remote), and sometimes the front doors will not unlock.
- The locking function sounds the same; i.e.: it makes a nice, firm clicking sound. Also, the manual lock/unlock on each door works easily.
- After a couple of days or if it warms up a bit, the power locks start working correctly again.
