I was trying to help lol. You have two options. The sensor and that may not fix the problem right off the bat or just buy a used seat and swap it. Just make sure if you have tan seats you get the right shade. On the drivers inner door under the label interior it will either say MT or MS. MT was for darker floors ivory seats and MS was sand color and tan seats and dash.So what you are telling us is that you want it for less?
Why not just buy the part you need, sensor, or seat... and install it... OH Wait, you can't find a wreck in that color... I bet you can if you buy just the sensor... 8)
