I am facing a problem with power sliding door on My 2007 Nissan Quest 3.5 S. The door is not opening using remote control or power buttons inside the van. I have to open it manually from outside the van. It is working sometimes but not all the time. But It is closing all time using power buttons.

It has only one power sliding door on passenger side and the other side is manual.

The problem is occuring after I did a complete detailing recently.

Any Idea to fix this ?

Thanks!!
