hello, I have recently purchased a 2009 black Corvette 06. The problem I am facing is whenever I drive my car red light to red light. The car begins to overheat and does not cool down. I'm not sure if the fan is not turning on or not but I know for a fact whenever I go over 55 mph. The car immediately begins to cool down if it was overheating, no matter how hot the temperature gets the car does not want to cool down unless I am going 55 mph. I am not sure what could be wrong.
Check the front of your radiator/AC condenser for something blocking it like a plastic bag or something. The radiator could just need to be blown out thoroughly.

There's nothing blocking it , it cools perfect when cruising at higher speeds just at low speeds it wants to overheat
Does your air conditioning work properly and have a sufficient charge to cool? If yes, and the A/C coolant pressure is sufficient, then your fan should come on when idling in your driveway and would be a good test for the fan function. If not, as suggested, locate your fan connector (a 3-prong connector) located towards the bottom of the fan assembly. Take it apart and check the center connector for any melting or burning. This is a common problem on the C6, especially if it has an aftermarket tune to increase the fan speed from stock.

I have noticed one thing and my ac does not blow cold when idle and only also blows cold once that car is speeding at or above 55mph , i will be checking as you suggested.

Just curious what temperatures you are seeing with the low speed driving.

It really depends it doesn't cool at any temperature at 240 i jus turn off . i've done thermostat and the sensor , going to check wiring again i guess .
I agree with you. The fact that his A/C isn't working until 55mph is telling you the airflow isn't there. I think the fans AND a shopping bag, or something, has lodged in front of the condenser.
Your over heating issue is most likely related to your A/C not blowing cold when you're at an idle...Fixing one will most likely fix the other, or at least have you on the right path to being cool once again

car doesn't cool down until I hit 55mph
