I have an 89 Delta 88 and if you have Electronic Climate Control there is a control module located just right(passenger side) of center at the firewall. It is in the same location as the blower fan resister assembly on a car with standard a/c controls.
The blower control module is defective.

No. An AC/heater control module is a computer that controls and automates the operation of the heating, ventilation, and air conditioning systems (HVAC).The blower resistor enables the blower motor to change the speed of the fan.
Try replacing blower control switch or module.
Replace blower control module. Usually the fan starts acting erraticaly and eventualy just stops.
Something called a blower control module takes the place and is found in the hole where you would find a blower resistor, so there isn't a blower resistor in that vehicle. As far as the blower control module is concerned, the module is serviced as a unit. No part can be fixed or replaced. This is not to be confused with the control head in the dash. The blower control module is held into the heater box with two 8mm screws outside the firewall under the hood, where you would normally find the blower resistor pack.
The blower control module has gone bad. Carquest has a new one for $20-$25 dollars.
The blower fan speed in a car is typically controlled by a resistor module or a variable speed control module, which adjust the voltage supplied to the fan motor. As the speed of the vehicle increases or decreases, sensors like the engine speed sensor or cabin temperature sensor may send signals to the control module, prompting it to adjust the fan speed accordingly to maintain a comfortable temperature inside the vehicle.
All electrical circuits in a vehicle have a fuse or circuit breaker somewhere. There are possibly three in the Taurus AC circuit plus a fan relay, a fan speed control module, and a climate control computer.
i think what you are refering to is a blower staying on all the time, if so the blower motor has shorted the control module, you need to replace the blower motor and control module.
Behind glove-box, behind engine control module
The 2000 Chevrolet Corvette blower motor control module can be found behind the passenger side dashboard. You will need to remove the dashboard in order to access the module.
