Cadillac Repair: 95 Cadillac Deville blower motor wont shut off, blower motor resistor, autoparts store

Question
I have a 1995 Cadillac Deville and when I shut the ignition off the blower motor starts back up and wont go off. I was told it might be the blower motor resistor and it would be located to the left of the blower and be held on by 3 screws I do not have one there it is just a plate held on by 3 screws no wires going to it and nothing inside under it. One autoparts store told me it has one but the dealership told me it don't. Also I can with the engine running shut it of by turning off the heat but starts right up after car is shut off. I also cannot control the fan speeds just one speed high. This all sounds like a resistor problem to me but I've removed dash and looked everywhere in engine compartment and under dash. I was also told it could be a module that may be built into the blower motor is this possible?
thanks

Answer
The fault could be the:

Blower motor, A/C programmer, Instrument panel cluster or an open wire.

The 95 does NOT have a BLOWER MODULE.
