1996 Geo Metro Front Wheel Drive Manual 155000 miles

I have been told to remove the dash in order to replace the heater core, but I am not sure what would happen if I mess with the air bags. The manual says to disarm them but it is really vague on where or how. How do I remove the dash without blowing the air bags, and then replace it so that they wont go off as soon as I reconnect the battery?
Do you
have the same problem?

Hello -

I will attach the info on the dash - air bag for you. Please be extremely careful when working with the airbags as even static can set them off. So be extremely careful even when you carry it.

Also many times you don't have to remove the dash airbag as the dash comes off with it connected after you unplug it. So look really close and again be careful.

I have given you what we have to remove both airbags to include the dash if you have to remove the dash one.

DO NOT turn the key on until all the connectors are plugged back in on those airbags. On many vehicles the system will do a self check and if a bag is not connected it will throw a fault and it can only be cleared by taking it to the dealer and putting it on their tester.....it runs the check and clears the light. So NO POWER on until all is back together.

I also gave you info on just the Metro not the Metro LSi.
