jusnice15 Posted March 20, 2013 Share Posted March 20, 2013 Hi all. I have a 09 accord and when the heat or ac is on the fan keeps going on and off every 30-45 seconds. I took it back to the Honda dealership and they said that it was fine, no problems. This doesn't sound right to me. Could it be some kind of sensor? Thanks for your help.

Jeff Collision Posted March 21, 2013 Share Posted March 21, 2013 The most common problem is a sticking radiator fan relay. Usually, you can confirm this by tapping on top of relay, or by swapping out with another relay in relay compartment. The other common cause is the fan control unit. This is mounted under the glove box directly between the two hinges. It's easy to replace. Quote Link to comment Share on other sites More sharing options...
