Rear Air Suspension Problems

[PARAGON]

You have a slow leak in a bag, line or connector. You can raise the rear (for off-road purposes) by pushing the button on the dash.

Do that, shut off the engine and then see if you can find where the air is leaking from. Maybe smoke a cigar while you are at it and see if the smoke swirls anywhere if can't hear the air escaping.

The compressor is running constantly because it's trying to play keep up with the leak while keeping the rear level.

Thank you for the response. But like I said before, the dealership had it for two days looking for a leak and could not find one. If they couldn't find one, I know I'm not going to be able to. Is it possible that the leak is in the compressor itself?

Don't assume the dealership simply is the last word on a subject.

There's a leak, go try to find it yourself. Air is escaping the system somewhere and until you either find out where or eliminate other areas, you are pretty much stuck, because your dealer has basically told you that they will simply replace it all to take care of the problem.

I had this problem also when i bought my 03 and this is how i found out the problem after the dealership looked at it 3 times. (you can also use this method to find a slow leak in a tire )
1. Get a spray bottle, put some baby shampoo or dish washing liquid and water in it.
2. Spray the mixture over each part of the air suspension components seperatly.
3. Watch for bubbles.

I would recommend to do one component at a time so you can realy analyze each part to see if there is a leak. Spray the mixture everywhere and heavy.
If you have a leak you will most likely find it.

I'm having rear air probs too. My service air suspension has been flashing since July. hehe. THink i'll try to look at it this weekend. Naaah!

I think you have a air leak also Tantric. If your compressor runs when the truck is running and your suspension drops when you shut it off. It sure would make me look for a air leak. Take some of wifeys dishwashing soap and put a little in a spray bottle with water . Then spray the bags, lines, fittings , compressor , etc. When you get done finding the leak , show us a pic of your wifes titties would ya?

Ok guys, I took your advice. After using the soap in a water bottle, I found bubbles on the right side air bag towards the bottom of the bag. I didn't see any sort of puncture though. I don't have the knowledge to disassemble anything, so I contacted a friend at a local speed shop. He said that I will need to order a new air bag assembly for that side. Would he be right, or do I have other options?

Thanks for all the help guys. You have saved me a bundle.

I have lost all faith in the techs at my local dealership.
