Driver side seat heater on all the time, momentary switch on seat just turns off the indicator as long as I hold it in. Supposed 10 minute timer doesn't shut it down. Passenger side is fine.
Before checking to see if the seat-mounted switch is really momentary or stuck on, I'm wondering if there's a common failure mechanism here. I suppose if the seat module's at fault I'm talking some bucks. In that case I might just unplug the seat heater in the spring.
There are also warnings in the service manual that advise disabling seat mounted side air bags and safety belt pretensioners before probing circuit connectors. It seems they could inflate in your face. So I also have to find out if I have these things. The vehicle has side air bags, but the "air bag" labelling for these is up near the tops of the doors. How do I know if I have safety belt pretensioners?
