hi guys i have a problem with an el falcon 6 cylinder i recently had removed the dash to replace heater fan and since doing that my air bag light has flashed a few times then stays on. the other problem is now the airbag light has suddenly stopped flashing but i now cant use my rear demister is this linked in some way and how do i fix this any ideas. would appreciate it. thanks

the bulbs in the dash tend to get loose when you touch them ...bend the pins down and check continuity of bulb with a multimeter.
do glis have a demister switch? in my fairmont when i pull the dash i always forget to plug it back in.
the airbag sensor and blue srs ecu are also pugged under the dash on the drivers side,the other sensor is next to the horn behind the front grill check they are all plugged in properly.

everything is plugged in the airbag light just stopped flashing one day and doesnt even come on when you first start the car. when you push the rear demister button it makes the econ light on the dash light up. go figure . any ideas as to what that might be or how to fix it.
