Reverse Warning Sensor Problem
First problem with my X! Notices I was not hearing the backup alarm as I approached objects anymore. Looked at the button on the dash, and it was lit up in the OFF setting. I pushed the button, but it stays lit up in the OFF setting. I put the trans in Park, the light goes off. Put it in Reverse, the OFF light comes on again.
Anyone had this problem before? Any ideas if this might be as simple as the switch?

Sounds like a reverse sensor ---
Does sound like a simple fix and it should be a warranty repair !!!
I use that backup alarm ALL the time --- I am more likely to back into a spot rather than pull in head first I like it so much !

How do I inspect the sensors? I have had this problem for over two weeks now. Can someone take me step by step through how to get to the sensors behind the bumper. I assume this is the area I should be concerned about.
And once again...specifically how did others resolve this exact problem?

I have a 2000 Excursion and I have had several problems with the reverse sensor system. I have had sensors replaced on 3 occasions. It seems that if 1 sensor is bad the whole system stops working and the off light is lit on the dash button. I also recall paying $145 for each sensor. My system is currently not working and I have given up on fixing it.
It was a nice idea by Ford, but it seems to be prone to failure.

No warranty left on my 2003 X. So that is why I am asking how to get to the sensors to at least do a manual check before I wait it out to see if the problem goes away or take it in for diagnosis.
If they malfunction when wet there has to be a way to get at them to manually dry them to see if that solves the problem. I just don't know how....

Did you take it to Ford for repair?
I keep hearing that if the sensors are wet this problem can happen. How does moisture make the "off" light come on? I am well aware (and have experienced) that moisture/ice etc can cause the sensor to beep but I think others are getting these two issues confused.
Seems like only a handful of us have actually had the "off" light no beep problem. So your insights would be helpful.

My system never seems to work for longer than a few months, so when I would have it into a Ford dealer for other service (pinion seal, rear end replacement, leaking front axle seal etc..) I would ask them to look at the rear sensing system and see why it's not working. Each time they said it was a bad sensor. I don't think it's an easy problem to diagnose because there was a couple hours of labor involved each time. I would like to find a cheap way to buy the sensors and just replace them all myself.
