I tried to replace my Ignition Switch with housing by taking off the steering wheel, removing blinker/wiper switches, removing steering column plate but can't get the housing off. I can't seem to drill through the screws to remove it and can't get the steering column off to try to remove housing. Thanks for all of your great advice but I now need to turn it over to a mechanic. How long would you expect it would take to take over where I left off??? An hour or so??
