90 Gt, had the ignition replaced under the recall right after I bought the car in 97. Lately, certain things like the signals, vert top motor, and heating/AC blower won't work unless I get the ignition switch in just the right position. I have to move it around every time I start the car, but once in position, it usually stays there. Does this sound like just the lock cylinder, and if so, what is required to replace it?
