91 Deville, Air blower motor will not turn off

Turned off car today and found that I cannot turn off the blower motor. When the engine was shut off the blower kept running. The air was comming out the bottom by your feet. No error codes. Removed 2 different fuses relating to air / heat under the dash and still it keeps running.

Blower module is faulty. Part number AC/Delco 15-72530. Price in 1999 was $75...dunno what it is now. This should be a good part number for your 1991 DeVille. Install is is located under the cowl near the blower.
Well that was it. Thank you very much.
