Chrysler Repair/2005 Pacifica Blend Door Gear


Hello, I have a 2005 Pacifica with dual-zone manual climate control and like several others have posted, I've had problems with the gear or spline on the blend door getting out of sync with the gear that it meshes with. Normally, with a little force, I can move the gears to get them back in sync and then everything works fine for a few months. This last time that I tried to adjust them the gear on the blend door broke. Is there a way to replace this gear. Do you have a Part number? Is it an easy process? Thanks!

Hi Dan,
I reviewed the question of how to deal with a broken gear on the blend door. While that specific problem is not discussed it is the case that any internal problem with the air distribution requires that the air distributing housing part of HVAC unit has to be removed from HVAC unit as a whole. Further, to remove that housing requires the removal of the entire HVAC unit as a whole from under the dash.  And that then involves removing of a great many connections of the unit to the car (heater/ac lines) and removal of the instrument panel in its entirety. All those are described in the '05 manual but it is apparently a very lengthy job.
I can only suggest that you examine the broken off gear and the part of the door to which it was originally attached if you can see that. Might it possible to use some two-part expoxy to reattach the gear to the door? I have used "J-B Weld" brand of epoxy to do such tasks.
The instructions for all the procedures for removal and installation probably is covered on 2-3 dozen pages in the manual which would be a bit of a task for me to do, one page at a time and attach to an email. It is possible but not something I would like to undertake if an alternative were worth trying. You might do well to go to a dealer parts department and ask to look at the parts manual to see if the door only can be purchased if you do decide to to that long route.
Please let me know of your decision.
