I have a 2013 ATS that has this issue where sometimes the sunroof wont close because if the windscreen netting. Sometimes it will and sometimes it won't it's just random does anyone know what I could do to fix this? And yes I'm sure that's what's causing it because if I hold down the screen with my hand then close it it closes every time, it seems to have the tiniest of bend to it but I'm pretty sure that it's been the same the entire time I've had it and nothing has really changed with it, and like I said sometimes it will close on its own and sometimes it won't. Any fixes or other having the same issues?

This happens to me too. I tried adding some lithium grease to the track, but it didn't help. What works for me 100% of the time is holding the sunroof close button at the first detent (so, not fully pushing it down yet) until the wind net screen pushes down, then I can fully press the button so that it auto closes the rest of the way. I have a similar issue if I pop the sunroof up and then try to auto close it. The sunroof actually hits the roof of the car and then pops back up again. If I lightly press the sunroof slide button, it ignores the resistance and actually closes down. Quirky, but usable, I guess.

The protective system for the sunroof is based upon total current draw of the motor so all of the various mechanical resistances in sum are what will trip the safety as current draw increases with increasing mechanical resistance and once the trip point is exceeded the motor will stop and then reverse. Holding the wind screen down overcomes part of the total resistance allowing the sunroof to work BUT the windscreen may not be the actual root cause.

Make sure that the track and seals are clean and the seals need to be treated with a LIGHT coating of silicone grease. I use grease in a can, if you use the spray stuff then apply it to a cloth and then to the weather stripping to avoid a mess but the solid stuff in a can or tube is a better solution. A little goes a LONG way so don't overdo it. With age, you may need to clean the original grease (with its now embedded grit) from the tracks and then apply new grease. WD-40 is a safe grease cutter but it is flammable. Use sparingly and remove residue with a dry cloth and give it an hour or so for the light distillates in WD-40 to evaporate before applying new track lubricant.

Manual mode overrides the safety stop/reverse over-current trip sensing system, just hold the switch at the FIRST detent until it closes. Be careful using the override function because if there is an obstruction on the track you can damage the drive mechanism. It won't hurt it to use it for overriding nuisance reversals due to slightly increased sliding resistance but inspect before using the override.
