Where is the collision reset switch on a 2001 Pontiac aztek?

There's no collision reset switch on a 2001 Pontiac Aztek (or any other car, for that matter). Airbag systems don't have a simple reset switch. If the airbags deployed, the system needs professional attention from a qualified mechanic or dealership. They'll need to diagnose the problem, replace necessary components (like the airbag module, sensors, or even the airbags themselves), and then reset the system using specialized diagnostic tools. Attempting to reset it yourself is dangerous and could lead to the system malfunctioning in a future accident.
