I did a search and found some info but not everything I needed. 98 Mystique LX 2.5L ATX 30K

It seems that my fans only work on high speed. If I turn the car on when it is cold in the morning and turn the A/C on the high speed fan kicks on after about 5 seconds. If I am not running A/C the fans kick on once the gauge is around m. From what I read if the engine is dead cold the fan, low or high speed should not kick on at all. I am not sure if the is caused by the relay or the something with the A/C. I am not really in danger of overheating but the high speed fan makes a lot of noise and I would like the car to run correctly.

Do I need to replace a relay or something else. Where is the relay locate on the fan in the engine bay?
