It sounds like you just have a bad engine coolant temperature sensor. You can test the sensor with a multi-meter if you have access to one. Do you plan to repair this yourself?

Oh ok. Testing the sensor is fairly straightforward, especially if the shop has a scan tool. You can use the scan tool to access the signal from the temperature sensor and then compare that with either a laser thermometer or by testing the resistance across the posts of the sensor. If the reading from the sensor on the scan tool is high and the engine isn't hot, and/of the resistance at the sensor is less than 800 ohms and the engine isn't hot then you know the sensor is bad.

Is the shop having a hard time finding the problem?
