Hello
I have this tune from GM LS3 E67. Fan will start but won?t shut off. I've read that it need that the vehicle reach up 40mph to have the fan system works properly but my VSS isn?t connected because old vehicle.
Read also another post about the van delay and tried to modify it but no luck.
I?m installing a SPAL PWM fan and tried also the PWM Electric @125Hz but seems not working for my fan.
Any suggestions will be apreciated.
