beats the **** out me...
i've never heard such noise and i have owned a bunch of explorers. does yours have remote start or some other add on? also, does it change/go away when you're messing with your climate control dials? grasping at straws here...
Possible that the truck had some type of GPS or Lo-Jack system installed in it at one time (maybe from the previous owner) and the Li-Ion battery is going out? Normally these are hardwired in, but most have a battery backup in them (just like a CPU in a computer....) and that may trigger the beeping?
That sound would drive me nuts
is it louder looking under the hood? possibly the belt or any of those components connected.
Do you have that progressive snapshot? I had it that thing beeped sometimes . I also don't recommend it at all because it destroyed one of my O2 sensors also read online people had the same problem with it.
I had a similar issue a few years back. Mine turned out to be an open rear hatch window. I had probably pressed the rear hatch button on the key fob by accident one day. The hatch just released enough to intermittently operate the alarm switch. I just re-closed the hatch window and end of problem. I understand that a defective side door latch switch can also cause an intermittent beep. My beep seemed to be coming from the right dash area but hard to narrow down.
It's gonna blow!!
That's a bummer, but I'll 3rd the after market device. Good luck finding it.
Not a sound that I have ever heard of in my 05. I 2nd the after market device idea.
Subscribing... Let us know if you find it...
Run a carfax on your ex. I'm curious if it was a rental car in the past. I bought mine used from a wholesale dealer. They had to remove some tracking device they said was causing problems before I could have it. Although I don't know what the problem was or if it was beeping. I did confirm with the dealer that after I saw the car fax and saw my ex was a rental car in the past that the tracker was from the rental company.
