Loss of One or More HVAC Blower Motor Speeds on Chevrolet Malibu

Problem Description and Possible Solution

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

My heat/ac will work, then it will stop working for a few days or weeks, then suddenly you turn the switch and it will come back on for a few days or weeks, then the cycle repeats. When this happens nothing on the dash will light up or work. The rear defroster button will not function, the ac button will not function, the fan switch will not function. Nothing works related to this area.
The blower doesn't turn on at all.
My second time in one year my hvac isnit working. No heat at the worst time. Why doss this keep happening it hasnt even been two years since ive owned the vechicle
the blower on my AC works intermittently it won't work at all and then when I'm driving it'll come on and then it shuts off again.
The blower motor stopped working at the lowest speed, then over time the second then third now the fourth speed has stopped working. I'm only left with the highest speed on the control switch that works. the repair was replacement faulty blower motor resistor block.
heat/air only worked on 4 and 5. now it isnt working at all
rolled down my windows to smoke a cigarette, turned of the air conditioning after done turned back on and not a single speed for blowers were working
my ac switch # 2 is not working....1-3-4-5-working.
im a grandma...what u recomend i should do?

Heat or air don't work
Air no longer comes out of vents unless at high speed with window cracked. Makes noise when turned on. But nothing comes out unless I'm moving.
2011 Chevy Malibu-fan went out, same problem as everyone else.
Heater motor does not blow any air. Temperature adjustments all work ,just no air to push the heat or ac.
Same issues with 4 and 5 only working when the switch decides to operate correctly. AC turns itself off and on. GM has replaced the switch 3 times 1 or 2 times was under warranty. Now the blower is going out.
ac/heat only works on 4 and 5
heater blower will not turn on
My 2010 Malibu's AC quits working the same time my temperature gauge is buried at lowest level. Sometimes the AC will come back on soon afterwards, or it will take days. I have noticed that if I shut the AC off before I shut the car off, then I normally do not have this problem. The issue is to remember that. When I do forget, I also found that if I turn the defrost setting on and the AC off, I have a quicker recover time for AC to start functioning again. I know this happened when my temperature gauge moves from lowest setting to the actual engine temperature.
What on earth is going on? Me thinks I'll give up on GM soon?
Air conditioner is on, cold air is fine, fan speed on High, not blowing thou, I can feel cold air coming out the vents real slow speed.
a/c turns off have to play w/ control
ac heat only works on 4 and 5
mine only works on 5 need to replace
