I discovered it was the fan control module. I found it on the internet for 150.00 plus 100 core. I googled the part # and thats how i found the company. My local cadillac dealer quoted me 402.

I have one of these cars that had that problem. I fixed mine with a new fan control module. The fan wires can be hooked up backwards to the module when you replace it too. I have a service manual on this car and can answer most questions as I have helped a lot of people with this year model. I will look at which fan should be pluged into where later. You should never straight wire a cooling fan as this will result in other problems because the engine will not come up to normal temperature resulting in poor fuel mileage. This could result in a exhaust converter and o2 sensor failure due to a rich fuel mixture. Reply and I will get back to you asap.
