viper 5301, anyone?

dued, I'm guessing that the problem with your vehicle is that the parking light output was connected to a wire at the dimmer switch which showed 12 volts with the parking lights switched on, when the installer tested it. It sounds like he connected it to the dash lights wire(which dims depending on how the switch is rotated), not the wire from the switch(which stays constant). This might not have caused much of a problem with the dimmer switch in full brightness, but could have fried the switch when it was rotated to a less bright position. In all likelihood an honest installation mistake, but if your switch is damaged they should replace it and fix the install.C Renner's Auto Electronix

thanks much chris wallace - bestbuy swore it was impossible, but we knew it was too much of a coincidence - the dimmer cost us $50, so with your explanation we will request that cost from them thanks again btw, they finally replaced the main computer in the 5301 and we have had no problems with it starting since, so the possibility of some bad units definitely exists which simply changing the trigger doesn't fix
