I had this problem some time ago. If I remember correctly, I removed the plastic panel beside the driver's seat to access the mechanism that controls the light. Again, if I remember this correctly, I simply cleaned the "contacts" in this part. I did not purchase any parts. .
My parents have this problem on their 99 Sienna. They got an estimate of an outrageous amount to fix the problem, because it involved disassembling the dash to reach the control for the seatbelt indicator, plus replacing a sensor. They've decided it's not worth it and have learned to ignore the annoying flashing light. Sorry.
There are two possibilities for the 'receiver' if you are getting a flashing seatbelt light. First, there are wires under the seat that detect when someone is sitting on the seat and then there is a sensor in the seatbelt receiver piece (the part with the release button where you click it to open the seatbelt) that senses when the seatbelt is correctly closed. The most likely problem is that your sensor in the seatbelt receiver is simply worn out.
