Why is there an intermittent rubbing/groaning noise from the dash when idling and at low speeds?

See if you can find the exact location of the noise.
When you replaced the blower, did you clean out the plenum all the way back to the air inlets? There is some play in the blower bearings which can cause rubbing when starved for air. Also, could be rubbing on debris in the plenum.
Another possible cause of this noise is a fluttering damper. Depending on the HVAC option you have, the mixing and duct selection dampers may not be opening/closing properly. If they are vacuum actuated, there may be a leak at or in a control solenoid or the switch. Try all temperature and vent settings to see if the noise changes. If they are working properly and the noise continues, then it's usually a blower problem or not the HVAC system making the noise.

I have no heat or air blowing out of my vents. Any ideas?

still nothing,????
why do this backwards. ??
or not using simple diagnosis>?
so really you failed to state the beginning symptoms?
was it just just noise. or noise and no blow.
or the noise is gone,, but my fix broke the blower.
there will no heat not moving, if the blower is dead.
get heat , moving in non circ, mode.?
sure i bet you do an that is SOMETHING.
does the blower make sounds like a normal blower, then if no air flow
the dampers are bad.

blower silent? on all speeds, , do say so.
blower works only on high (sounds) ?
if the blower is running, surely you can hear it spin fast.
and there is no flow, the damper is bad or the blower fan blade set screw
is missing and or loose. did you check that screw first. before.
replacing the motor? id not ever skip that step.
we can not help you ,with no facts or symptoms but still nothing.

Heater blower not working

well it migh be the fuse, blower resistor or the blower motor. was the blower blower noisy when it last ran ? sometimes you can TAP on the motor and it will spark it back to life BUT the motor may take out the blower speed control aka resistor or module. so hear is how i would start my check.. with a 12 volt test light probe. check all of your fuses, then go to the blower motor and check for power threw all speeds but first make sure the motor has a ground signal.
if the motor is bad they are not bad expensive around 40 bucks same goes for the speed control, but a bad motor can wipe out a speed control, and they are a non returnable part.. see how to find control and motor. ho How To Install Replace AC Heater Fan Speed Resistor Chevy Cobalt 05 10... hope this helps, and get it fixed as it's a safety issue, it helps keep the windshield clean and fog free !

Heat or a/c blows only one speed /high only

90% of the time it is a faulty blower motor resistor. The sound when you turn off your HVAC is probably a squeaking from the blower motor fan or the pressure dissipating internally from the AC system. These are normal sounds.

My blower runs on high for awhile but only works when I fiddle with the knob what is the problem?

It sounds like you have two issues.
The fan only runs on high because you have a bad resistor for the fan motor. ( the high speed is the only speed that doesn't run through the resistor.

I believe you also have a bad fan speed switch.

I hope this helps you.

Making a real loud noise when it starts, dissipates after awhile

The bendix in your starter motor (which is the ring gear that pushes out to engage with the flywheel) is faulty and not retracting after the car starts. The starter may be able to be repaired by replacing the bendix, but if it was me, I'd just replace the whole starter motor right off the bat.

The blower motor is shorting out.Replacement is the only option.If the speeds don`t work,replace the blower resister also,next to the blower motor.I hope this was some help to you.

I would bet the cabin/pollen filter has not been changed for a long time. This can cause lots of issues including incipient blower motor failure. For illustrated tutorials on all things ACC related for Saab 9-5, including step by step replacement and repair procedures, see this site under A/C and climate control.
