Re: rear air springs
I am willing to bet its a bad sensor. Not a bad bag. Bottom line is you have to take it to the stealer to find out. You cant work on it yourself without the tech2.
I had the same problem this year.

Re: rear air springs
YOU PROBABLY NEED TO REPLACE THE BAGS, mine loose air if left undriven a week or so . as far as I know the only place to get new ones is the stealer . you do not have to use a tec 2 tool . you take the neg battery cable off raise the vehicle with the wheels hanging and replace the bags reconect the battery cable . and start and drive . I need a set myself for my 03,if I had the part # and could get a deal I would buy them myself. if anyone knows how to get them at wholesale let me know .

Re: rear air springs
I agree, when replacing bags the tech 2 is not required, any sensors, module or compressor replacement would require a trim height learn to be done.

Re: rear air springs
I recently took the airbags off of my ride and don't even use them. When I studied them, they are actually in great condition, and look like they were replaced before I got my ride a couple years ago, so they are definitely newer than my ride. I will sell them to you if you can throw out a price... I will see what they are worth new and give you some sort of deal, since I do not use them anymore. Also, like someone said earlier in this post, you might want to double check that it's not a hose that's leaking and not the airbag. Those airbags are pretty tough, so if one had a leak, I would imagine it would split across and tear open, as with a hole in it, I don't think it would hold the pressure very well.

Re: rear air springs
on my 03 the bags look dry cracked at the bottoms (like dry tiney cracks you get on tires ) the best price I have found is $120.41 each for new OEM bags. I know as soon as I buy them an aftermarket company will make them and sell them for $80.00 each witch is all there worth anyway .

Re: rear air springs
Yea, we're seeing some higher mileage 03's needing air bags lately. They leak at the bottom where they fold under. I just use soapy water in a spray bottle to find the leak. Just like in a tire.
