My air bag light is on the windows will not roll up or down and my air/heat doesnt work.

I don't know if your talking to somebody to somebody else or what? If you stay on your original post, the person you were talking to will get back to you. Usually with multiple issues, I pick one system and check voltage and ground for that system, fixing one system may or may not fix the others.

I haven't looked at your wiring info, yet. If all three systems get ignition feed, meaning the circuits go hot when you turn on the key, that is where I would start testing, for voltage.

You said you checked wiring, but, I don't know which system? I guess if the wire inside the insulation broke, the insulation may stretch? I can't see much from here.

Just to add, I looked at wiring for the power windows, sedan. It shows a power window circuit breaker, voltage to the circuit breaker goes hot with the key on. Use a test lite, check for voltage at the circuit breaker, key on. If no voltage, I'd have to check feed to and from ignition switch. Go from there.

It just dawned on me, when you said the wire stretches, if your talking about a fusible link, then yes it sounds faulty.
