Good Luck...it's not too bad of a job & if your state allows it, used parts or parts from eBay should be ok

Clean contacts group under the passenger seat
Code 37 is for the passenger's side impact module. This code is usually caused by a bad connection at the harness underneath the passengers seat. Usually disconnecting the harness and reconnecting it will fix it.
The Airbag Code 36 for a 2001 Ford Taurus is the airbag code for the Driver Side, Side Airbag. This means that there is either a faulty connection, and wires may need to be cleaned, or that the driver side, side airbag needs to be replaced.
The airbag light turns on when the airbag computer detects a malfunction and sets a code.
The airbag computer has detected a malfunction and set a code.
Code 37 is improper voltage level in the side airbag on the passenger side. This could be caused by a short to ground or, more likely, a high resistance connection between the restraints control module and the PS side airbag assembly. Even if your truck doesn't have the optional side airbags, it still has the wiring for them and uses a yellow resistor cap to simulate the side airbag. Same story - probably a poor connection at the RCM or at the resistor cap under the passenger seat. Working on the SRS can be very hazardous so unless you are comfortable working on this system, take it to a professional for repair.
