Attempted to open my sunroof for the 1st time this year and noticed the auto feature was not working. I had to hold the button to pull the SR forward or back. Any idea where the problem may be? Is it a DIY fix?

 

did you disconnect the battery at all, probebly need to re- learn the sunroof.

this is how i got mine to work.

Thanks ARMENDS500...it worked! Ironically, my battery died a week ago because I left the lights on while parked at the airport. Never used the sunroof until the other day, so I didn't pick up the problem earlier. Saved me at $100 diagnostic!

 

i'm glad it worked out for you.
