Is my ignition cylinder going out? January 05, 2009, 11:57:33 AM Sometimes when I turn the key to start, it will make a little click but doesn't crank. The clock and dome light will go out, then come back on when I release the key. I'll have to try it several times and then the car will finally crank and start.Sometimes it doesn't do that at all.Everything else works fine...is this a sign my ignition cylinder is going out, or just some screwed up wiring?

Is my ignition cylinder going out? Reply #3 – January 05, 2009, 05:31:47 PM It's not a bad job. There are two Torx bolts in the steering column that hold it in. I can't remember what else is involved. Quote Selected

AFIK the dome light is totally independent of the ign SW, I'd be looking for a bad battery cable or ground...Could have a bad cell in the battery...A short in the ign switch circuit that pulls enough current to kill the dome light, is going to cause smoke...
