I'm having a overheating problem with my sons car with air conditioner on. Had a specialist friend do the whole nine yards on the A/C. Air working great but car temperature still wants to go up in traffic or drive thrust while ac is on. Come to find out it has 2 electric fans only one is working. Was going to buy a new fan assembly there a 165 bucks for anyone that needs to know. After talking with a buddy I was directed here. Rather than buying new fans the issue could most likely be the relay. How do I know which relay it is and where is it at on the 2005g35x thanks in advance for any help
