2nd Gen '87 Sun Roof problem
 

My sunroof has worked DECENTLY for the most part of the 6 years me/my brother have owned it. The only original problem we had was having to give it a good push upward to open vertically before it retracted. Now, all of a sudden, the sunroof is having issues moving forward and back as well. Sometimes it gets stuck and just wont move at all and I have to give it a push or a pull. It has never done this before, and it seems odd to work "fine" and then just stop. The only thing I've done differently recently is give it a good thorough washing. I can't see how this could have damaged it, because the sunroof was closed tightly, and we dried the whole thing off way before I tried opening it.

If anyone has any ideas about this, please let me know. I'm thinking the motor for the sunroof is probably just gone bad or something. I'll just have to add that to my list of replacements.

open the sunroof,get a good silicone spray lube and go to town with it.,.Open/close it a couple times to get the slider lubricated.

I agree with previous post.
Same thing happened on my mx3 a while back.
If you can hear the motor trying to work, it may be fine. May have to push it open manually, but use some good cleaner and a brush to thoroughly clean out the tracks before lubricating it.
Doing that worked on mine, though I still have to give it a nudge to open it vertically. May have to adjust linkage to fix that, but I haven't bothered to try it...

Thank you. I know my brother previously sprayed it with, I believe, WD40 (don't quote me) and it made it worse for awhile. I'll try what you said.

WD40 alone won't be that effective, especially if there's a lot of 'gunk' in those rails. Get rid of the gunk first. I used cheap carb cleaner (since it'd evaporate quick and I didn't want a mess inside the car) and an old toothbrush. I later grabbed a wire brush because I had some stubborn gunk. Try not to scratch up the rail surface if you use a hard wire brush.
Clean it well, then lubricate it. Silicone spray lubricant works great. I used Tri-Flow, a teflon lubricant used on mountain bikes and outdoor stuff.

Just as an update, I haven't gotten around to doing what you guys told me yet, but I tried my sunroof today and it worked like it used to. Now I'm debating whether or not it was just the cold that made it sluggish the other day. I'm still going to clean it good though.
