Do you need to replace speed sensors & control units of airbags if their blown or just the actual bag? Does anyone know what airbags are compatible for a 2000 Grand Am? 1999 - 2005? What about from Grand Prixs or Bonnevilles?

Are you attempting to do this yourself, these systems are not to be toyed with, let me know what's what here.` Your questions tell me you are in a learning mode with this type of repair.

Well, i'm just looking to find out what it would cost to repair blown airbags. I probably wouldnt do ti myself - just buy the needed airbags/modules/whatever and have a mechanic do it properly and would like to see from what vehicles I could use on the 2000 Grand Am(I'm looking on Ebay and the more compatible types of airbags the better).

Besides the air bags the SDM must be replaced and any arming sensor near or at the impact point. Also possible clock spring. SDM for 2000-2001 are the same,, it seems 2000 air bags stand alone, I would check this info with a Pontiac dealer for the latest info.
