I had the same problem(s).

First the outside door handle froze, had to thaw it with a blow dryer.

Then the Bowden cable connector (inside door handle to door latch) broke, so I replaced the cable.

Then the electric door lock actuator started to ‘stick’ on lock/unlock, sometimes wouldn’t work at all.

Then the outside door handle assembly broke inside the door itself. DOH!

Here are the parts I replaced:

01 DOOR LOCK WITH MOTOR ACTUATOR, LEFT 51218402537
05 BOWDEN CABLE, DOOR OPENER, FRONT 51218403057
03 BLIND PLUG 51211975404
12 HANDLE BRACKET BASE, LEFT 51218243629
13 LOCK CYLINDER BASE LEFT 51218243631
15 CARRIER, OUTSIDE DOOR HANDLE, FRONT LEFT 51218243615

Cost about $350, took ½ a day to do it all.

Door opens & closes like NEW!!
