Hi guys..pretty new here..but I bought a used 04 runner sport edition in may of 2006 and in the fall, probably october or so I opened the moonroof one day and it didnt want to slide back shut, finally after pulling and such it finally closed but now i'm afraid to open it and since the weather got colder i havent tried nor do i want to for fear of it not closing...it will tilt up and down fine though, just not slide shut once oepend...so what can i do about this? easy fix by toyota dealership? how much might it cost by them? also have noticed within the last few weeks my rear hatch door when i open it it very very slowly rises up to open, it seems like i have to wait a good amount of seconds for it to raise up and finally just bend down underneaht it to reach into the back area, any causes for this? thanks for the help
