One problem related to air bag on-off switch has been reported for the 2005 Chrysler Town & Country. The most recently reported issues are listed below.
The front passenger airbag light often comes on my 2005 Chrysler town and country when the steering wheel is turned. I took it to the dealer when this happened the first time, and they replaced the wiring harness for the airbag, but the problem still occurs. Also, the headlamps often fail to turn on when the switch is turned. Turning the switch on and off several times usually solves the problem, but lately it seems to be getting worse.
