Does it restart? What other symptoms? What does it do at idle in park and you turn on the A/C?
The car will restart only if the fan is off. If the car is in idle/park and the fan is turned on, the engine will turn off. These are the only symptoms.
No noise? Does the A/C compressor come on? ANY non-factory wiring , that you know of?
No on all.
I'm sorry , but just to clarify , you could drive all day long , as long as you don't turn on the interior blower motor?
That's right.
