1999 Chevy Cavalier Cooling Fan

Hi, I have 1999 Chev Cavalier and I had noticed that my engine is getting warmer than usual. We checked the Fan, and the relay to be sure that they a both working and they are working perfectly. So we decided to hard wire the fan to run all the time while driving to keep the engine cooled enough and if I do a longer period of time driving then I will turn the car off but leave the fan run until it cools off. Could this cause problems for my car engine down the road doing this and I have a sensor to replace and the I will be reinsalling the cooling fan to operate as normal. I am doin this repair from home and from looking around the engine compartment I am not able to determine where the the sensor is for the cooling fan. Do you have a diagram and what wires to check just in case there is a wiring problem instead of the sensor?

Thank you!
