3 climate control issues:

1) My car seems to only have one temp level, (hot) regardless of where the rotary temp switch is on or fan setting.
2) When set on just the lower level or econ. setting, hot air is blown out of the dash vents. Is that normal?
3) My fan seems to only have one setting, low.

Could it be the control pushbutton assembly?

Any help or ideas?
Thanks in advance
Dan
