If you have DTC 15, the fans should be running all the time.

 

Well I don't have that code anymore fixed it, so if I got dtc 15 that means my fans are constantly running then why is my temp gauge getting so high like right at the red Mark almost.

 

engine still running very hot...says check gages on dash so i drove home and parked it right away. i believe my fans are not turning on i replaced the relays and checked the fuses and they are all brand new. any other ideas as to why the fan isnt turning on like its supposed to?
