    I know sometimes snow on the sensors can screw mine up. Can't tell if snow is an issue where you live based on your supplied info. Also, make sure you did not accidentally hit the parking assist off button. My 07 has one of those buttons, and I am thinking yours might too.

    Hey coral-reef.

    Did you figure this out and get your audio back for the parking sensors?

    I had the same problem, turned out one of the sensors came unplugged. The little clip that had held it in broke. I had to use tape to hold it on tight, and now it works fine.

    if a sensor is bad will it also mute the sound? if so, how does one know which is bad?

    will confirm nothing is unplugged 1st.

    Yes, the sound was muted when it was unplugged. It could also be a bad wire (although I have heard of the sensors getting damaged.)

    Re: Rear parking sensors not working

    I just purchased my used 05 ext. I have noticed that i have the same problem. My single red light continues to blink but no yellow light nor any sound!!! i backed into my fence the first time i tried because i wanted to see how accurate they were!!! damn things don't work at all.. Im planning on taking my truck to get it fixed soon if nobody on here has any other advice for this problem. thanks.

    Re: Rear parking sensors not working

    If anyone knows how to diagonse the sensors to find the failed ones, and could share with us, that'd be much appreicated.

    I dont wanna replace them all if I dont have to.

    Some beeping assistance when I back up would be GREAT.

    Re: Rear parking sensors not working

    Well i finally got to the bottom of this problem. I got bored this evening and decided to go outside and see if i could tackle this sensor issue.. I crawled under the back bumper and inspected all the sensor connections. I noticed that one sensor wasn't even plugged in. So i plugged it in and drove the vehicle in reverse. I ended up with the SAME issue. Just one red blinking light with no noise.

    So then i crawled back under there and noticed that the connection on that plug wasn't the greatest so i pushed it on as tight as i could and tightened it down as best i could with a zip tie. I then hopped back in and drove in reverse and all of the sudden there was a yellow light as well as noise. It is now working perfectly!!! This would be much easier to trouble shoot with two people so the one under the car could squeeze the plugs tighter as the other person keeps there foot on the brake to see if the yellow light comes on!! good luck.

    Congratulations, That is exactly what was wrong with mine. I used tape to create the good connection, but the zip tie seems like a great Idea. By the way, I have four sensors that are new if anybody wants them. I purchased them before I found my bad connection. $200 for the set shipped.

    Thanks. Mine has not worked since I bought it, I went under and they all looked good but i pushed them all tight anyways and now they work. I guess I should have tried that sooner.

    Re: Rear parking sensors not working

    I've got one that's unplugged, I tried to plug it in but it doesnt stay clicked in.

    Havent had the chance to do the "2 person" method, but I will try soon as I can, the weather here in NY has been COLD so its not even an option at this point to try. Hopefully I can get it plugged in or at least zip tie it as mentioned and have it work

    If not at least I have a feeling I know which sensor is bad (the unplugged one)

    There is a diagnostic link in a similar thread using tag URPA, Ultrasonic Rear Parking Assist.

    If you can't find it, reply to my post here and I will get the email.

    I can't figure out to get to my sensor in my '01 deville.
