internal fan is working intermittently sometimes it comes on

Customer Question

internal fan is working intermittently sometimes it comes on straight away when start up. If it does not come on, it does not come on even if you change fan speed settings or heat settings. It will just start working by itself sometime while driving, sometimes 15 mins after starting driving. It can work without issue for days then start acting up. Car is a 2009 2lt. diesel s-line
