Hello, I'm new to the forum. I just bought a used 2007 Cobalt LS. I'm looking for information about adding power door locks, power windows and cruise control. From everything I've been able to dig up so far it looks like all this is a fairly easy mod to make. I would like to get feedback from anyone that has installed power windows or door locks using one of the kits from eBay. They are very inexpensive but I am afraid the quality and function would match the price! Any suggestions?
