Detach the LH front door lower frame bracket garnish through its clip and claw with a screwdriver shielded by tape. To disassemble the LH side front door window regulator you must first detach its assist grip cover through 11 claws then take off the front armrest base panel upper LH which calls for removing a clip and 5 claws plus disconnecting the switch connector before slowly extracting the window regulator master switch. You can detach the front door handle bezel plug after eliminating its claw and then unscrew and pull out the front door trim board sub-assembly LH when you apply protection tape, remove the 3 screws, detach the 9 clips, and carefully move the trim horizontally to avoid damaging its pins. To access the front door components you must detach the claw holding the outer rear view mirror LH, take apart the front No. 1 and No. 2 speaker assemblies also detach and disconnect the front door belt moulding LH. To expose the front door hardware you must uninstall 2 bolts from the side Air Bag sensor, front door service hole cover, and front door No. 1 stiffener cushion. Before starting disable the window switch and move forward the glass panel to reveal two bolts for extraction. The front door window regulator sub-assembly LH disconnects when bolt A loosens from its socket after unplugging the connector. Apply standard marks on the power window regulator motor assembly LH front before removing its three T25 "TORX" screws with tool. Remove lower rear support of the front door frame assembly by unscrewing one bolt while taking off the front door outside handle cover LH component using a T30 "TORX" socket. Use a T30 torque socket wrench to take out 3 screws and remove the front door lock assembly LH. Then pull and slide the front door handle assembly outside LH from its position. Remove the front door outside handle frame sub-assembly LH by loosening its T25 TORX screw with a wrench then using pliers to compress the clip and pulling out the lock control rod. To disconnect the exterior pads of the front door handle you must pry off their 2 claw fasteners and unbolt the front door check assembly using 1 bolt plus 2 nuts. After detaching all 19 clips use a clip remover to remove Weather Strip from the front door LH side. Reset the Weather Strip if damaged during installation.
