Anyone else ever have a problem with this. I turn the heater, or the A/C on, and it only blows high, their is no other choices, high or off. when i put it on low or medium, it just blows high. Could this be a problem with a resistor or something??, best way to fix the problem? should i replace all of the heating controls??.

By the way this is for a 99 suburban base model
