A/C and Heater aren't working
I have a 2007 Hyundai Accent and the A/C and Heater aren't working, yesterday my dad and I were on our way to a mechanic and he was messing with the fan speeds and out of nowhere the heater came on. So my dad though it was the control that wasn't working so we went to an auto parts store and he told a worker about the problem and the worker told him that the Climate Control Resistor needed to be replaced. We got the new Climate Control Resistor and installed it but my A/C and Heater still isn't working, so now we are thinking that the problem might be the control or the blower. Does anybody know what the problem might be ?
