The blower fan in my 2000 Oldsmobile Intrigue does not worked. It initially worked on high settings but not low, and then quit altogether. The problem began after passenger side floor board began to get flooded with water and engine ran hot. I put stop leak in the radiator and the flooding and overheating stopped. The fan stopped working later. What could be causing the problem? The module, the blower resistor or the blower motor? Checked wiring and Power is going in, but not coming out.

do you mean you have the blower motor working but you have no heat.if so then with the motor at operating temperature then grab the heater hoses and see if they are both the same temperature.if they aren`t then the heater core will have to be replaced.make sure the thermostat is working properly.
The blower motor fan is controlled by the blower motor resistor.Its the resistor which controls the fan on respective speed which you select.But if the resistor goes faulty,then it will not be able to set the required speed which you set for fan,so it works on high speed only.
In this case you will have to replace the blower motor resistor.
Check fog for the location of blower motor resistor location:--- see part number 8 in the diagram below.
The blower motor resistor is located next to blower motor under the dash.Its fitted with 2 screws and a wiring connector.You have to remove the screws and wiring connector and take the resistor out and place the new resistor in same position and connect the connector as well as screws.
this should help.Thanks.Helpmech.
This is a common problem when the heater resistor goes bad. It is located near or mounted on the blower motor. Replacing the resistor module will fix the problem. FYI, Sometimes the blower motor is still working but the bearings are going bad. This tends to cause premature failure of the motor resistors. (So if the resistors fail again I would suggest replacing the blower motor as well.)
