I HAVE A 99 INFINITY QX4 AND WHEN I TURN ON MY AC/HEAT IT COMES ON BUT DOESN'T BLOW. I FIND THAT WHEN I DRIVE AT A CONSTANT SPEED (I.E. ON THE HIGHWAY) IT BLOWS OUT AIR/HEAT BUT I HAVE NO CONTROL OVER HOW HARD IT BLOWS OUT, ONLY CONTROL OVER TEMPERATURE... WHAT COULD SOME POSSIBLE ISSUES BE?

The blower fan isn't working. Check the fuse first. If it's not that, then see if the blower is getting voltage when it's on (voltage varies with blower speed). If the voltage is present at the blower connector, then the blower fan is probably bad. If it's not then it could be the control itself (manual or auto if there's climate control).
What your feeling now is just the air that flows through when your moving forward.

I have 2003 Infiniti G35. A/c works sometimes and then goes off.Comes back on several days later. Same with heater. You can feel cold/heat but the blower won"t work.
