HVAC Blower doesn't run when engine is running
As the post indicates my 2013 427 HVAC blower has stopped. The blower motor has been replaced with a quality replacement part as I assumed initially that was the problem but I was incorrect. If the car is placed in run mode without the engine started the blower motorcycles through all the speeds normally with good power output. when the engine is started the blower motor runs for approximately 3 seconds then stops. The control panel appears normal and goes through the fan speeds on the display normally but the motor does not run at all. I've traced fuses and have power in all appropriate locations except for at the blower motor. My only assumption is that this is a control module issue but before I spend the money to replace it would like to know if anyone out there has had a similar experience. Summer is coming to Texas and I'd like to get this fixed sooner than later without an expensive trip to my local dealer. Any help or suggestions would be appreciated.
