>>>Yes, it's stock.   In fact virtually all modern automobiles (at least the 
few that I've looked at) with the A/C condensor located with the water 
radiator are wired so that when you turn on the A/C, the radiator fan comes on also.  
 Remember, unlike a Pantera, those other cars don't have a dedicated fan for 
the A/C condensor; since both condensor and radiator share a single fan (or 
single set of fans), then either condition triggers the fan.

When Panteras are modified to move the A/C up front, one of the modifications 
includes dual-triggering the radiator fans as per the above.

which didn't blow; instead they melted internally, invisible to the eye.   They 
looked great but didn't conduct any electricity...
