OK i fixed it!! I didnt need to buy any new parts or bring it to the dealer! Here is how it works. On the end of the track where the belt rests when the door is closed, are two switches. One of these switches is pushed when the belt goes to the end, and it tells the motor to stop. This worked fine. The other switch is the problem switch. When the switch is up, the contacts are touching each other and completing the circuit. When this happens, it knows to slide the belt across. ONce the belt gets to the end, it pushed this switch, along with the first one, and stops pulling. when the circuit is broken, via the switch being pushed, it knows that the belt is by th seat. So, when the door opens, and the circuit is broken, it knows the slide the belt towards the front of the car, if the door is closed and the circuit is completed, it knows the belt is up by the windsheild and needs to slide toward the seat.
here is what causes the problem. the cable that pulls and pushes the seatbelt back and forth is covered in a thick graphite type grease. this grease oozes out over time and gets all over the switch closest to it, the one that senses the position of the belt and knows to push it or pull it. Once the grease gets inside the switch, it covers the metal contacts on both sides of circuit within the switch. once the contacts are covered, the circuit is broken and the car thinks the belt is in thge right position with the door closed, since the circuit is broken, so it doesnt pull it towards the seat. once the door is opened, it tries to pull the belt back towards the windshield, but it is already sitting there, so it stops. this is what was causing my problem
solution: i pulled the switch that gets covered in grease out, and cleaned it.
for those of you having the problem, here is what to do. While sitting in the passenger seat, pull off the panel that is shaped kind of like a letter t. it has two screws in it, and is on the roof, as well as the side by the seatbelt. at the end of the track is a little black box with 3 screws holding the front panel on. pull this off, along with the next plastic panel behind it, which is smaller. you will see the two switches, which look like little black rectangles. on the right of these switches you can see the gray cable that pulls the seatbelt. the switch you want is the one on the right, and it also the one higher up. pull both switches out, and follow the wires down under the next panel and unplug the harness. pull this off the car. now is the tricky part. the switch you want has a green plastic peice holding it together. you have to pull the top sheath off the switch. i used a small screwdriver and needle nose pliers to pull it apart. now you can see the inside. a spring, and the small metal contacts. make sure not to lose anything, they are very small parts, and remember how it goes back together!! now, spray each part really well with carb cleaner and clean them gently with a toothbrush, or q tip, or whatever you want. once you get all of the thick gray grease off, put it back together! viola! Also, look all around where the switch fits in, and above it. scrape out all of the excess goop with a thin flat screwdriver. there is a ton of it!! once you put it all back together, plug it in and watch it work!! sorry i dont have pictures.
hope this helps anyone with problems! thanks everyone for trying to help me out! hope this helps you poot, and freakmech! it is well worth it in my opinion, took me about a half hour once i figured out what i needed to do.
. its definately a glitch in the system, its fairly common.
one of those will work for me when it does that, but its random lol. oh well now i know what that box is for in the center console
