Sunroof in my car doesn't retain its memory. After I do sunroof calibration procedure I can use tilt function and Auto ON/OFF.
But overnight it forgets it and I have to do calibration again. Everything else (clock, radio, trip computer, etc...) hold their values. Without memory sunroof just opens and closes while you hold button. Any ideas?

 

 

care to explain a little more OP?
i dont think i know what you are talking about, my sunfoor only has 3 functions ( that i am aware of). open, close, tilt. you are saying that we can make it memorize what? what calibration are you talking about?

 

In some cases like changing battery, no power for a long time, etc... your sunroof will have only 2 functions Manual open/close. In order to make it tilt and open/close automatically you need to relearn (or recalibrate it). As far as I can remember in my case it happened after battery change. Now when I come to my car at morning I can only open/close sunroof manually (holding button). When I recalibrate it it works fine (open/close auto + tilt) until car stays for a while (overnight).
