Has anyone ever done this? I use my 95 caprice for work, making deliveries so I am constantly sitting at traffic signals or idling outside of delivery locations. I don't like the high temp setting that these cars come programmed before the fan kicks in, I have heard of having the computer reflashed but this is my only car and I can have it down more then a day. I'm looking for any insight on how I can wire in a toggle switch so I can flip the fan on when in traffic or when at the delivery. I appreciate any help that can be offered.
