What is the torque spec on the oil drain plug on a 2002 Suzuki Esteem?
The Suzuki oil drain plug torque specification is 30 pounds. Over tightening the oil drain plug can cause the oil pan threads to strip.
I had this problem on my 1998 Suzuki Esteem and it was the connector under the dash near the steering wheel. The wire going to the brake light was bad inside the connector. I had to tear it apart and fix the connector right where the wire was inserted into the connector, it had turned brown and mostly melted. I repaired the wire going into the connector and all is back to normal working operation.
