So whats the question WHY? Could be a bunch of things. How about checking the fuse first.

Under the dashboard on the passenger side. 3 7mm hexhead bolts.

The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.

sounds like a defective blower module

A 1998 Cadillac Deville does not have a blower relay. The system has a fuse and a controller to feed power to the blower motor.

If the blower motor quits, replace the motor. If it freezes over have the a/c checked. I want to know what genus came up with the answer above me you guys serious

The blower motors only work with the engine running. If the blower motor has three wires on the electrical plug, then the blower motor module is built into the unit & it's very expensive. Sometimes, you can tap on the motor with a hammer & it may work or slowly turn. If this is the case, replace the blower motor.

Blower motor speed resistors are generally located close to the blower motor.

faulty blower module. Under hood not far from blower motor

Probably the blower motor, wiring to it or control switch

Inside dashboard in path of air that blower motor blows.

If the blower motor is bad then you need to replace it, you don't repair it. The blower is located under the hood and you will need loosen the cradle bolts to rock the engine to remove the blower motor. Book time for this job is 2 hours................

Remove the front floor kick-up panel.Remove the cover from the I/P electrical center.Remove the BLO MOT (blower motor) MaxiFuse No. 49 from the I/P electrical center.Remove the right side instrument panel lower insulator panel.Disconnect the blower motor resistor electrical connector from the blower motor.Disconnect the blower motor cooling tube from the HVAC module.Remove the three blower motor retaining screws.Remove the blower motor with fan from the HVAC module.

It is on the fire wall (center), un-plug the connector, remove the three screws that holds the blower in place, on top of the blower motor is a inspection cover that has two screws, I removed them first, you do not have to remove the weight that is on the out side (three screws) un less you think it is in you way, good luck.

No, there is no fuse, it is self contained. get a new blower motor

Inside the blower motor housing directly behind the electrical coupler.

Is it the blower motor or is it the fans in the front?if its the fans they will come on at anytime to help cool engine down better.If its the blower motor for the interior heat and air you got a electrical problem.

If it is the blower motor for your heater then it is definatly you blower resistor

The blower motor relay on a 1980 Cadillac Coupe Deville is situated on the passenger side. It is located in the vicinity of the firewall and is just below the windshield.

Check to see if you are getting power to motorIf so motor is defectiveIf not check fuses and relay

If you have no blower speeds at all check the fuse, then check the blower motor switch and electrical plug for a melt down situation, then check the blower motor itself.

the blower motor is located on the passenger side of the interior under the glovebox.

If you have checked the blower motor and it does function when power is applied then I would suspect the Blower Motor Resistor Pack is defective. It is also possible the blower motor speed control is bad, but highly unlikely.
