My back up alarm hasn't been working all the time. I checked for the clicking sound when it wasn't working & could hear the clicking. The light is on all the time when its acting up. IS there a control box somewhere?

 

bump, anybody works some of the time?

 

No, I don't have that problem. Mine goes off when nothing is behind it or when I have a trailer connected. It used to cut itself off when I had a trailer harness plugged in. Now it just beeps. (As if I didn't know I have a travel trailer behind me ). If you find out something, post it up. Thanks.

 

Hook up a scanner to your truck, like auto enginuity or something. If you have a sensor on the bumper go bad it will show up as a soft code (doesn't make the check engine light come on).

 

Mine works intermittantly. It tends to work more often in damp weather. The dealership ran codes on it and told me there's a control module behind the passenger side kick panel. I bought extra spot mirrors as a remedy to a $200-300 module.

 

thanks 5wests, are you talking about the back panel with the jack?

 

No, from what I understood they were talking about the front passenger side kick panel....in front of the door by the passenger's feet.

 

If the speaker for the backup alarm in the rear is bad it also will not work.

 

The speaker was squeaking(not beeping) today, so maybe its bad?

 

Only one way to find out. Plug in a makeshift temporary speaker and let us know if it worked.
