Hi and thanks for using 2CarPros.
It sounds like there is a short to power. Do me a favor, I attached a diagnostic flow chart for this symptom. Also, I attached a schematic for the cooling fan circuit (picture 2). There are three relays which control the fan speed. If you removed one relay at a time, it could have kept running. Next, I attached a diagnostic flow chart for the temperature gauge. It requires a live data scanner. See picture 3. Pictures 4 and 5 are of the power distribution box under the hood. It shows where the three relays are located and fuses.
Here is a link that shows how to test a relay:
You will need to use a test light for testing the relay. Here is a link that shows how to use one:
Let me know if any of this helps.
