Default Overheating Problems

My 99 Vette (ls1) is overheating and the fans are not coming on. I checked the relays and they are good. I ran a wire from the battery to the fan motor and the fans came on. Does anybody have an idea on what might be the problem? Let me know, Thanks

Probally your rad and your A/C condenser is plugged up. Common problem this time of year. Blow it out with compressed air and see how much junk you get out. Sometimes a water hose will work also.

How hot is it getting? With A/C off, fans don't come on until over 225 degrees.

Also check the fan grounds. They come together at a single point...ground pack at the right forward frame rail on top, next to the hood riser.
