How's this for a lousy update:
This afternoon I noticed that the high beams will come on with the lever forward, but will not 'flash' (lever drawn backward). Another new development is that the pwr seats will work only with either the driver or passenger door open! This was not the case yesterday... I recall that this is the default mode for when the ignition is not 'on' - I don't know the significance of this though.
Thanks for any input - I'm pretty freaked out...
