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 .

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.
