Q: I have a 2007 Jeep Commander that has a problem with the rear hatch door. When the doors are locked, the hatch door can be opened, and it activates the alarm. Interested in hearing if you have seen this. Any information you can provide would be helpful.
A: I have had this problem in my shop with a few Jeeps. We have found electrical problems with the actuators. The interior of the rear hatch has to be stripped down. With a wiring diagram in hand, you want to have a helper activate the door lock and unlock buttons while you are holding a test light to the wiring. The good part of this whole situation is the parts for your rear hatch are readily available and reasonably priced.
Car Care Tip: Spring is right around the corner. You want to check your air-conditioning system now before the repair shop bays get backed up.
