Has any one had the experience of replacing the ignition switch (AC DELCO gray housing) only to find out it was defective. While I had my steering wheel apart searching for the grinding noise I decided to replace ignition switch that I had in my glove box for about a year. After numerous attempts to get it started and doing fuse checks, ground checks, charging battery. I decided to install old switch that I never had problems with. Guess it works like it is supposed to. Another case of WHY ME!!!!!!!
