I'm sorry the Tech you requested was unavailable to assist you today. It appears that Tech is currently "Offline". Now that his 15 minute "request lock" has expired, hopefully I can be of some assistance in his place...When the Blower Motor continues to run even with the ignition off, this is most commonly due to a problem with the Heat-A/C Programmer. It's located behind the passenger's side dash (click here for image). To gain proper access, the glove compartment will need to be removed. Inspect the electrical connector and wire harness for any loose, broken, damaged or melted wires. If the visual inspection checks ok, replacing the Programmer should solve the problem.
