Nissan Repair: 1993 Nissan G-20, turn signal switch, hi john

Question
What is the cause of the lights abd horn staying on after the engine is shut off?

Answer
Hi John -

Looks like you have a short in your steering column harness, perhaps at the turn signal switch.

Remove the plastic housing around the column and disconnect the harness. If the problem goes away, then replace the turn signal switch.

Hope this helps -
