Car Forum / Nissan / Nissan Cars / October 2008sun roof is confused
2001 nissan path fndr - sun roof works if you push button over and over to close or open, it will go about twoinches then I push button again and it goes another two inches, it used to be push button once and sun roof would open all the way and close all the way with out all this hurkey jerky stuff. any suggestions of what could be wrong? > 2001 nissan path fndr - sun roof works if you push button over and over to > close or open, it will go about twoinches then I push button again and it > goes another two inches, it used to be push button once and sun roof would > open all the way and close all the way with out all this hurkey jerky stuff. > any suggestions of what could be wrong? > If it were me, the first place I would look would be in the switch itself. Is it dirty, worn, broken?  SignatureBill In Hamptonburgh, NY in my parents caterra, there was a procedure in the owners manual to reset/relearn the positions. Don't know if this applies to Nissan at all... >> 2001 nissan path fndr - sun roof works if you push button over and over >> to [quoted text clipped - 7 lines] > If it were me, the first place I would look would be in the switch itself. > Is it dirty, worn, broken?

It has lost its memory of where the glass is. Mine did this when I replaced the battery. If you work it all the way open and then all the way closed (2 inches at a time...), it should re-learn and start working correctly again. My 2002 Pathfinder has the exact same problem. I have tried the above several times without any luck. I resorted to leaving it closed for the last year. Please post the resolution if you get it working correctly. My '01 PF had this problem. Dealer replaced the motor assembly on warantee. It worked for a month and started doing it again. That was a couple of years ago, and it's been doing it ever since. I just went out to try the "learning" trick belowm and it worked. BEFORE I did the learning trick. Wierd. However, it's clear that this is a common problem. I got an e-mail a couple of days ago from someone who read my original post on the problem. > On 2/20/06 6:50 PM, in article 5c2fb0594166c@uwe, "khope" <u18935@uwe> > wrote: [quoted text clipped - 8 lines] > the battery.

I tried the "learning" trick, and it didn't help. I tried pulling the fuses (#11 and #24), and it didn't help. Any ideas? > My '01 PF had this problem.

If you work it all the way open and then all the way closed (2 >> inches at a time...), it should re-learn and start working correctly again. According to the FSM, what is happening is that the cpu in the sunroof motor has detected an "interruption" during an automatic close operation and the 5 inch move is the fail-safe action. It detects this by monitoring the limit switch and an encoder built into the motor. Here is the diagnostic procedure in the fsm for "Power sunroof cannot be opened or closed fully." (this seems to be the closest diagnostic to this problem): 1. Initialize full closed position. 2. Check the following. a. Check obstacles in sunroof, etc. b. Check worn or deformed sunroof. c. Check sunroof sash tilted too far inward or outward. 3. Check sunroof switch. 4. Check harness between sunroof motor and sunroof switch. 5. Replace sunroof motor. The "official" learning trick from the FSM is slightly different from the process that worked for me a couple times before (see below), though from my experience with my '02 it doesn't always work either. The book says "Set lid assembly to fully closed position by operating OPEN switch and TILT switch. After the lid has closed all the way, keep pushing the tilting switch toward tilt DOWN for more than 1 second." My sunroof forgot how to close last summer after a 75 mile run on the interstate with the sunroof open. It completely lost tract of where "closed" was and would not respond to any of the likely reinitialization procedures that have been posted. It didn't work right for about two weeks, then one day the "keep holding the tilt switch" trick suddenly worked and it has been fine ever since. I'm thinking something got stuck (limit switch?) and after a couple of weeks popped loose and started working again all by itself.

If you work it all the way open and then all the way closed (2 >>> inches at a time...), it should re-learn and start working correctly again. Sorry to dredge up this really ancient thread, but: after a while, my '01 PF started having the same problem again. This persisted for about a year, and I tried several things: disconnecting the battery, pulling a couple of different fuses, etc. It was not partuclarly a big deal because I almost never run the sun roof fully open open, just tipped up in back to increase the airflow in sunny California. This past weekend for other reasons, I had the battery out overnight. This morning I noticed that the sunroof was working correctly again. I think it takes a long powerdown to get the sunroof computer to reboot. I've surely lost my radio presets (yawn) and I'm amazed the the keyless remotes still work (HUZZAH Nissan). > My '01 PF had this problem. Dealer replaced the motor assembly on > warantee.

If you work it all the way open and then all the way closed (2 >> inches at a time...), it should re-learn and start working correctly again. I'm going to dredge it up yet again, this time with the fix. I found a Nissan TechTip on Sunroof Motor Replacement that gives the calibration procedures. On the right hand side of the sunroof opening are two small round holes. The farther, smaller, one is only obvious if you tip up the sunroof. Line up the two holes (this will be a bit fiddly to get just right.). Record your radio presets. Disconnect battery for a couple of minutes. Reconnect battery. Run the sunroof all the way back and all the way forward (the TechTip says don't use the automatic mode, but I accidentally did and it worked ). Reset the radio presets. > Sorry to dredge up this really ancient thread, but: after a while, my '01 PF started > having the same problem again.

If you work it all the way open and then all the way closed (2 >>> inches at a time...), it should re-learn and start working correctly again. I fixed mine! It was the memory, just like the previous poster said, but closing it and opening it all day long won't fix it. Here's what I did: I closed it all the way then pulled the power window fuse for a few seconds then put it back in. Now it works perfectly. >On 2/20/06 6:50 PM, in article 5c2fb0594166c@uwe, "khope" <u18935@uwe> >wrote: [quoted text clipped - 8 lines] >the battery.

My owners manual had the answer: With roof fully closed, press and hold the "tilt down" button for more than one second. This fixed mine. Randy > I fixed mine!
