Ignition switch/blower motor

When I start my car, there is usually a beeping/alarm that "confirms" proper ignition. I have been having a problem recently where I start my car, there is NO beeping, and my fan/blower for the A/C or heater won't come on. I sometime have to start and re-start my car several times before the beeping for proper start, and the fan will come on. I suspect this is a blower motor resistor going bad. Anyone have any input as far as this problems goes? Thanks!!!
