Hey guys, sorry I'm new and this is my first post.. So far I've read a ton of threads relating to my issue and have done everything to diagnose the problem however, I am still stuck.. Also don't know much but trying to learn how to work on a cars so kill me. Willing to learn.. ok. So cooling fans aren't working.. Fans work when I jump them from the battery.. Relays are good… Fans kick it when I unplug them from the CTS after about 20 sec like it says on the posts… My car runs hot only when I'm in traffic and stop as no wind is hitting the radiator.. Fans DO NOT come on when I turn on my a/c. A/C even on cold is always hot.. Whats my next move? Is it a faulty CTS? Is it wiring? Is it me? Taking her on her first road trip this weekend and do not want the car to overheat if I am stuck in traffic. Has new radiator new upper and lower hoses. Didn't know what a thermostat was when I flushed the old radiator fluid but now I do and willing to change if needed but I do not think that is the problem.. Thanks guys.
