1998 ford expedition clicking noise from center console?

I have a 1998 ford expedition. There's a clicking noise coming from the console between the drivers seat and passengers seat. I thought it was the cd player i had installed in it. But i unplug that and it still does it. I notice last winter when the rear climate control was turned on it started doing this. And now when i set the rear blower to low it doesn't sound as loud. Is there a fuse or something that can be taken out and if so which one is it? Or any ideas what has to be done?

There might be a relay under the console that's making the noise or the actuator for the rear climate control system may be the source of the noise.A relay makes a clicking sound when it is activated. You can always remove the console to see exactly what the noises source is. If it makes the noise only when the rear fan is turned on, it could possibly be the blower motor resistor, if the rear fan has a separate resistor.I'm most likely thinking it may be the relay making this noise. Does it click one time or does it continue clicking on a repetitive note? If its a relay, it should only click once. If it is an actuator, they tend to click repetitively when they begin to malfunction. Check the fuse box under the dash and the relay panel under the hood for any fuses related to the rear climate control system and maybe even the front system too.Remove a fuse 1 at a time until you find the fuse that stops the clicking noise.
