Ok, here's the deal - its on my sister's 1999 Alero.

The hvac fans don't work at all some times, its not just 1-2 speeds. When they do come on, they work normally at the regular fan speed, but then they'll just go off all of a sudden.

Sometimes it will work better if the blower is off when the car is started - then it works for about 30 seconds and shuts off.

Who's got some ideas, maybe a resistor or gas tank problem? :rolleyes:

Oh, no SVS codes btw
