This is a lot to ask but… have a 2001 Town & Country with 157,000 miles. The driver rear automatic sliding door will not work. You can hear the motor running but it doesn’t totally close…so I open and close manually. I looked in Chrysler service manual…could this be a power latch assembly?? How hard would it be to replace myself (dealer wants $600). The rear hatch is the same way have to manually open/close…can hear motor and it goes through motions but doesn’t open. ??? Then today the rear wiper wouldn’t work…any ideas. Appreciate any help on what I can do myself.
