2

Examine the door for proper fit and alignment, loose/ hard or torn seals, worn teeth
on the rack and gear (lower drive unit) or anything that would cause an obstruction
to proper operation.
Manually operate the other sliding door or of a known good vehicle and notice the
effort needed to open and close.
Compare the effort needed on the disabled door.
Does it take more effort to operate the door than it should?

All

Yes

With the DRBIII

t in Inputs/Outputs, read the PAWL, RATCHET and FULL OPEN

switch state.
While observing the FULL OPEN switch state, manually move the door from full
open to part open. The switch should toggle from CLOSED to OPEN.
Move the door to the full open position. While observing the PAWL switch state, click
the latch with a screwdriver to the first detent. The PAWL should toggle from
CLOSED to OPEN.
