Hey guys I'm new to the forum. I have a 2004 Monte Carlo Ls, that I picked up late last year. I am slowly making it my own whenever I have some money. My current project is installing a Viper 5901 Remote Start/Alarm. I have complete functionality of the alarm and remote start. The only thing that I have not been able to figure out is how to do the rear defroster as it is a soft button. If someone would have some insight into how to do this that would be awesome!!
