Ignition problems

[Wroughtironworker]

Started about 2 years ago.  Went to crank and wouldn't start.  Had brake light and abs lights on, a/c blower non fictional.  Through some forums it was suggested to be the ignition switch.   Replace it and it was all good for a several months.  Within the last few months ive had similar trouble and replaced ignition switches a few times.  This week I've had it not start a few times.  It's very aggravating.  I'm not sure where to start testing.   Any ideas on this issue?

Clean the ground wires, on the Frame BODY MOUNT extension, just below the drivers door, on the rear side of the mount extension. Do it RIGHT as corrosion can creep inside the wires. Should be 3 there. 2 in one spot and 1 in another nearby. This is the BCM ground. It may help your problem. If not its ready to be done anyway to avoid other issues. Good Luck

Thanks, will give it a try.  I was looking for aa wiring diagram for the ignition switch also but have not found a decent one yet.
