I just bought a 90 teg and the drivers side wont go back automatically, i took the fuse out for the passive restraint system under the hood and muscled the latch back where it is supposed to be and it has yet to go forward since. I just unbuckle it like a reg seatbelt except i always end up feeling stupid when i reach high instead of low when putting it on... I know when i had my supercharged thunderbird it would sometimes stay forward on the drivers side, on the latch inside the door there was a small sensor switch thing that when the latch would close it would trip it to send the seatbelt back, i took it off and cleaned it and greased it and they worked fine for a good while on the bird after that until it started again and i unplugged the sensor and it stayed back all the time, i dont know if the teg would be a similar setup but its worth a look
