Having problems with your 2005 Honda Civic ?
2003 civic temps go up with ac on
\015 My temp goes up with the AC on and when I turn of the AC temp goes down slowly. Any sugestions.\015
Seems like the a/c radiator fan is not working. Either the fan itself is broken, or the power wires that drive it are not connected. The fan is tripped by a/c compressor activity, and goes through a relay unit, which actually trips the voltage that feed this particular fan. You can check fan activity with car parked, and turning on the a/c . if you cant recognize the louder noise of this fan, stick a straw into the fan to check if it is turning. Careful with fingers.
