demons in my car?

Thanks everyone for the reply yesterday on the oil I should use.

Well this morning my heater seemed to be possessed. I could not get the air
to go on the windshield nor the foot well (which was a problem because I
needed to clear the windshield this morning).

It didn't matter if I press the up or down buttons or even the windshield
defog button - all I got has hot air coming from all the middle vents. It
wasn't until I got to work 30mins later that suddenly it all worked!!!!

Now when I first started the car this morning I heard a high pitched motor
noise coming from the right hand side of the dash. do you think this might
be related?

Thanks all for your comments.
