ACC II
Motors
The motors the ACC II system use
are stepper motors. They are much more reliable than their
predecessors. If they exhibit a problem, you might try spraying them
with a good contact cleaner before condemning them. Make sure they
are securely attached to their mounts, many times they can work
loose. LocTite on their mounting screws can help the problem. Pay
close attention to the pins in the connectors going to them, they can
spread open or get pushed back in the connector and make intermittant
contact. Tightening and cleaning the pins solves a lot of problems as
well.
Before removing a distribution drum
motor, make sure the climate control is set to HI and the key turned
on in order for the system to position the flaps at this setting.
Otherwise, you will experience difficultly reinstalling the motor. if
a new motor is to be fitted, Plug it into the connector and turn the
key on with the temp selected to HI to run it to a position where it
will be easier to install.
