99 4.3L 4x4
sup...
got a '99 blazer 4.3L with teh auto 4x4, 4hi, 4lo pushbutton transfer.
keeps throwing "service 4x4" light... sometimes resolved by the time i start again, sometimes resolved just by turning the ignition off and on again. when it throws the service light, the transfer selector switch briefly "blinks" (once) very quickly then all lights go out.
i'm also hearing a pretty significant "whine" (such as a tranny in reverse) coming from either the tranny or xfercase, noticeable at slow speeds (less than 30mph) but in general a LOT of drivetrain noise. all drivetrain fluids were changed about 500 miles ago when i had the sunshell replaced. i'm hoping the tranny service didn't trigger this.
any ideas? fuses are OK.
