Sunroof wont close on 1990 celica gti

some cars sunroof regulators come with a couple settings in sunroof
1 the 30 degree back tilt
2 half open stop sun roof
3 full open sunroof
these are common on sunroofs

now lets look at what could be the cause
bad regulator or needed greased gears
track needs to be cleaned which can stick the wheels down
most sunroofed vehicle regulators or gear boxes you will find in the trunk way up by the wheel wells in that little compartment tight to get out
also there should be a manual crank for sunroof placed somewhere in vehicle i know for my bmw it was back in the trunk on the gear box you will have to call dealer or look in manual to find sunroof manual crank and how to close
recommend taken to the closes dealer and have them service your sunroof mechanicals and have it cleaned up
sunroofs like cars needs to be cleaned on a certain milelage interval so that it will work for a long time
