My A/C stopped working and my blower only works on high. My heat still works but no cold air. I've read that my blower can be fixed by replacing the resistor but will that fix my A/C too?

Only on high does not effect the A/C not working. For the blower on high issue, first check the blower motor relay before going to the blower motor resistor. Is the A/C blowing out at all? If so, check for low coolant level in radiator and check refrigerant level of A/C system.

Check if it has freon if not the compressor will not come on also for your high speed only-test the blower motor resistor
