Yes, there is a blower motor under the dash. The squeal you described sounds like the motor locked up. The lubricant dries up causing the motor to lock-up. If you plan to replace the motor yourself, let me know. I'll try to get you a printout of where the motor is located. It will be under the dash on the passenger side, and will require that you remove part of the dash.
Let me know if I can help.
