Water can enter the starter motor. In cold temperatures, the water can freeze, preventing the starter motor from cranking the engine.


Replace the starter motor assembly, if needed.


  1. Confirm that the engine does not crank.
  2. Inspect the starter motor for signs of icing. If icing is found, warm up the starter motor either by gently applying heat or allowing the vehicle to thaw inside the shop environment.
  3. After the thawing period, attempt to crank/start the engine.

If the engine starts, replace the starter.

If the engine doesn’t crank/start, continue with normal troubleshooting.
