03 A4 1.8T Fan not engaging
 

Hey guys, I am new to the forum. Neither of my fans are engaging at all. Temp and A/C is fine while driving at decent speed, but when in traffic or idling for a few minutes it will start to overheat and of course blow hot air. Any suggestions? Could it be a fuse or relay? Thanks!

Well one fan should be mechanical in which case you should replace the clutch part of the fan.
As for the electric fan i would check the power going to the fan. Often times there is voltage there its the fan that goes out.
