hello-
i have a 99 olds alero 3.4, 80k miles.
engine runs well for the most part, although subpar mpg.

the problem is that the instrument panel, power windows and ac blower
are not operating. the gauges (tachometer, fuel, temp, speed) are
stuck on zero, and the panel lights dont work. the hvac blower will
not turn on, the windows wont go up or down. after ten minutes of
driving the blower (if the knob is turned up) and instrument panel
will suddenly turn on for a minute or so, then die. this cycle will
repeat.

these symptoms first started out once a week, but now have escalated
to all the time. finally, dtc codes p1665 and p1676 set (with engine
check light coming on).

the stereo, courtesy lights, door locks, head lights, engine, work
fine.

i suspect the problem is a bad ground, loose/poor connection, and the
troublecodes dealing with the EVAP system are just symptoms of the
universal problem.

any advice?
