Where is the collision reset switch on a 2005 dodge caravan?

There isn't a single "collision reset switch" on a 2005 Dodge Caravan (or any other car for that matter). The systems that might be affected by a collision (airbags, seatbelt pretensioners, etc.) don't have a simple on/off switch.

If you're experiencing issues related to a collision, like malfunctioning airbags or seatbelts, you'll need to take your vehicle to a qualified mechanic or a dealership. They will use diagnostic tools to identify and address the problem. The systems involved often require specialized tools and expertise to reset or repair. Simply trying to "reset" something yourself could be dangerous and could damage the vehicle further.
