Cadillac Escalade, EXT and ESV Forum - 1999 - 2006 Discussion, Rear parking sensors not working in Cadillac Escalade Forums; When I go into reverse all I get is one blinking red light and no audio???
Any idae on the ...
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.
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.
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.
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)
