Diesel truck starts fine. Idles up in cold. Runs fine. Sitting in cab I hear a random clicking. This sound comes and goes. Driving down the highway at 70 it will do it. After an hour or so it won't do it any more. If I shut the truck off and start it again the random clicking will resume it comes and goes ? Any ideas where to start looking.
It sounds like the click from dead batteries but the batteries will turn over engine and start with no problems.

 

Mine is making the same kind of noise took it in and Ford said temperature actuator for the climate control. They are going to replace it on Thursday said it would take all day the whole dash has to come apart.

 

Dash has to come out , Well thats a this summer when it's warm project.
Not looking forward this job.

 

update on this clicking sound, wife has noticed that the sound will go away when the brakes are applied.
any thoughts on what this might be?
Im going to look for the temperature actuator for climate control when i get home and the weather is a bit nicer. thats my first place to look so far, only got one reply to my post.

 

My clicking would not go away by putting on the brakes, so you may have something else going on. Mine no longer clicks now that they changed out the temperature actuator.

 

Hi, I got the same ticking sound. Did Ford replace it on warranty? If they did there are reference to a TSB or anything I could take to my dealer.
Thanks

 

They replaced mine under warranty. I had an extended warrenty though.

 

sound like the multi function switch

 

Hello I realize this post is from 2004 but I;m having the same issue with my 2004 f250 and like you mentioned with your wife step on the brake and noise stops!! Did your issue get resolved and if so what was the major malfuntion?

The brake light switch was the solution when my 2003 F250 had the same problem. It’s located on the back of the brake pedal up towards the top. Hope this helps.

 

My 1999 f350 just recently started this but I lost the speedometer and the o/d light flashes
