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?
