My Stanza has 150,000 miles. For years, occasionally when I turn the key to crank, all I hear is a faint whir behind me. The second try always works. I'd like to be sure the switch contacts are clean.
Lately, I have sometimes had trouble unlocking the cylinder; other times, it is smooth. I'd like to be sure the tumblers are clean and lubricated.
I'd like to remove the lock cylinder and switch for cleaning. The manual says to break the screws that hold the assembly to the steering column. Is that the only way?
Besides the four wires running to the switch, I see two running to the side of the cylinder. I haven't found them in the wiring diagram. What are they for?
