Repair of sunroof so it will close/open
My sunroof is stuck in the 85% close position. Pushing either the open/close switch you just hear a 'rattat-tat' sound and the sunroof remains in the same position for most of the time. Some times it does move half an inch either way but that's all. I need to get under the headliner and be able to see if there are any small bolts loose/missing and what the track assembly looks like. Can you help and by chance also provide me with an excerpt from the factory service manual?
Sure. I thought I included it. It's a 2006 Mazda 3 and is a 4dr. Can you also find info for removing a portion of the overhead headliner in order to be able to work on the sunroof motor and track assembly?
Many Japanese cars' are designed similarly in that the fixes are the same. Check the owners manual for a method to "reprogram" the limit on the sunroof and/or windows.
I had half of the headliner removed before I looked in the book. Your window is confused and forgot where it is currently positioned! (Don't laugh most automotive accessories are controlled through the onboard computer and just like your laptop can drop a bit or two and lock up or crash, no pun intended.)
1. Disconnect the Negative battery terminal.
2. Wait a few minutes and reconnect the battery.
3. Operate the window by closing it fully and without releasing the button, hold the button for about ten seconds after it is fully closed.
4. Open the window fully and once again hold the for ten seconds after it is fully open.
This should reset the end limits for the window. Check the owners manual for specifics on the car. This procedure may also work for some "auto up/down" windows.
Finish the fix by reprogramming the radio presets, bluetooth, programmable seats, etc.
Forgot to add this in the original. The car I was working on was a 2004 Nissan Sentra. It also works on other Nissan models as late as 2009 model year.
I thought I was the only 2006 Mazda 3 with this problem :) Glad to hear I'm not alone.
I started a thread on this subject here:
I'm currently fixing this problem for the second time.. but I ran into a snag.. the motor got indexed wrong and now thinks the glass panel is "up" in the rear.. I have to try it in all positions until it re-indexes correctly.
So.. tell me.. do you have the sport tune suspension? and low profile tires? and drive lots of miles? and live in a dusty area?
All those apply to me, so I'm wondering if there any common conditions that cause the roof movement to stiffen up.
