I have a 2009 silverado LT and has DL8 mirrors and I would like to replace them with the DL3 mirrors with the puddle lamp and fold option. I've got the new mirrors and can already see I need the [COLOR=blue ! important][COLOR=blue ! important]drivers[/COLOR][/COLOR] switch/control panel. Do I need to replace the passenger one also? I'm also guessing I'll need to have the [COLOR=blue ! important][COLOR=blue ! important]computer[/COLOR][/COLOR] re-flashed after replacing these 4 things so they will work. HELP captrcpjr@gmail.com
