89 Deville 4.5l Coolant Temp Fan light on

The check engine light will come on followed by the Coolant Temp Fan light. The light is right, the coolant fans are not running. Where do I start looking for the cause of the problem? Note! this car has 140,000 miles but less than 1000 in the last two years.

You probably have burned out fans. They come out easily, and cost about $150.00 each.
