I've got some air suspension issues.. I recently replaced all 4 airbags(they were leaking)... I then noticed that it took a 15 minutes for the car to rise.. Now, the car wont rise at all. I took the car to a friends shop. He tested blowing air into each line and we noticed that the car would rise corresponding to each line. He mentioned that there wasnt much air coming out of the valve blocks. So, I'm thinking its either the valve block or the air compressor. The air compression seems to be on and running.. Is there a way to tell if its the a compressor or the valve blocks?

Thanks

 

first check for codes in the system then check for air leaks,then check the valve block for leaks as long as that is ok with disco mike... MR. know it all,then I would check the compressor ring,which wears out occassionally...good luck...ps call me and I'll walk you through it
