:confused: I have a 2001 limited edition excursion, 4x4 V-10.

The Backup alarm has stopped working. I can push the button so that the off lamp is not illuminating, but as soon as I put it in reverse, the off lamp comes back on, and of course I dont get an audible reverse tone.

I also have a very sporadic operating Trip Computer (overhead console). It usually starts working after i have been driving for several miles, or it may work to start with, then go out later.

The reason i mention both of these in the same forum, is that they are on the same fuse.??? I sthis a coincidence? i have changed the fuse.

Please advise.

 

I had to disconnect my reverse sensor speaker when I was plowing the other day. I think the sensors got iced over b/c everytime I put the truck in reverse the sensors would go off. It was terrible! I followed the sound to the back of the truck and unplugged the speaker. I'm not even sure that I'm going to hook it back up b/c it's been a pain for me. Good luck!

Hi Cterry:
You surely are aware that there is a reverse sensing shut off switch located on the dash. Why not use it instead of disconnecting the beeper, I do when towing, works well. Or, do you have an aftermarket back up alarm? THAT will drive you and your neighbors nuts; makes the Excursion sound like agarbage truck when backing.

 

Every time you take it out of Reverse and put back into drive you have to push that button the next time you put it in reverse. Easier to unhook the speaker instead of pushing the button 400 times when you're plowing.

Chris:
I see your problem much clearer now, but wonder if the '04's might be wired differently. When I use my ('04) Excursion off- road, the sensors accumulate dust, and instead of sounding the alarm, they just quit working.
