Conditions: Some customers may comment about sliding side doors that are hard to open or close when operating;
1. from the outside of the vehicle.
2. from the inside of the vehicle.

Causes: 1. Hard opening/closing efforts from the outside may be due to:
a. binding conditions of a misaligned/misadjusted door.
b. rubber bumper missing from levers on the outside handle, (related to closing efforts, hard to unlatch from open position).
c. binding at lower latch when closing.
d. sticking of the weatherstrip to the painted surfaces of the door opening.
2. Hard opening efforts from the inside may be due to:
a. binding conditions of a misaligned/misadjusted door.
b. broken or cracked inside handle casting limiting rod travel.
c. binding at the lower latch when closing.
d. sticking of the weatherstrip to the painted surfaces of the door opening.





Diagnosis: 1. When properly aligned, the sliding side door should present a uniform even appearance regarding GAP in side view (see Figure 1). The section views in Figure 1 will provide the dimensions and tolerance ranges for flushness checks. If alignment of the door is suspect, refer to Correction # 1, install new rear center roller bracket and apply a coating of silicone to the weatherstrip.





NOTE: New Rear Center Roller Bracket Assembly consists of the following: (See Figure 2)
1 - 10196002 - Bracket, Rear Center Side door roller
1 - 10196003 - Bracket, Rear Center Side door (door side)
1 - 10196004 - Pin, Rear Center Side door bracket
1 - 10186320 - Retainer, Rear Center Roller Bracket pin


2. Outside handles suspected of missing a rubber bumper may be checked by lightly moving the handle fore/aft and noting free play present. If handle has more than slight free play (1.0 to 2.0 mm), OR if the handle does not return to a "centered" position when released, rubber bumper is probably missing, refer to Correction # 2, (see Figure 3).
3. Broken/cracked inside handles may be identified by close visual inspection of the pivot area on the handle, OR if the handle does not return to a "centered" position when released, refer to Correction # 3.





4. Binding when closing may occur at the lower bracket latch and striker area. Ensure that new clip P/N 10186100 is installed when doing Corrections # 2 OR # 3, (see Figure 4).
