Hey need some help. So I been restoring my LC bit by bit. When I bought the car sunroof was fine now it kinda starts to open but doesn't open. I may have previously cleaned it too well and not greased it again. I hope it's not jammed cables etc. Is it easy to remove the glass so I could try some grease and try opening closing without the glass on it and see where the problem might be? I had cleaned the front 2 drain tubes when the sunroof was working (only tried to open sunroof after about 6 months to realise it's not opening. No leaks or anything like that.
