2005 Chevrolet Cobalt Q&A

2005 Chevrolet Cobalt Question: The heating and a/c does not work in my car what could be the problem?

I changed the blower motor resistor. But the switch to control the temperature still doesn't work but I also did some research and it said it could be the blower motor itself. Any ideas on how to find out what the problem is? -
