what the heck is going on with my 2004 Pontiac Grand...

...Prix? We replaced the ac blower motor and when connected it won't shut off and doesn't respond to the hi/low control on the dash. Even when the car is turned off, the motor still blows. The condensor engages with dash controls just not the blower. Help!

Suggest you've got a problem with either the switch in the climate controls or the ignition. Are there any other accessories that remain on when they should be off, like the radio or the like?

I would check to make sure the car does not have a afterblow kit on it
the kits were intended to let the blower run for a few minutes after the car is shut off to keep the bacteria from forming on the condensor and creating odors they would time out after a preset time, but if the module is bad it could be stuck on your dealer should be able to tell if you have one or not ..
