Blower fan not working properly

Hello Gang,
I was wondering if I could get some help. I searched about it on this forum and just assumed that I needed to replace the blower motor. But the fan will work from time to time. Today (with the AC on) the blower motor was costantly changing speeds although the controls were on for it to blow full force. I read something about a resistor that goes bad. Any Ideas? TIA
