Hello I just bought the car listed above. The air compressor is running, but loud. It raises the car and suddenly it lowers the front side. I hear a hissing sound from passenger side when the car is raising. I know the air compressor is bad, but could it be a the struts leaking since it has a hissing sound? Can someone please help me out?Also, both the green light and yellow light comes on, but green one stays on.

The compressor could be loud because you have a leak somewhere causing the compressor to be louder then normal. Get a empty pump spray bottle and mix up a strong mix of soap and water in the spray bottle. Then spray around where you hear the hissing and watch for bubbles.

There is a hissing sound coming from the passenger side. Can you please tell me if there is a diagram where the feeding lines are located at?

The compressor can be good, but if it keeps running all the time it will burn out. I have never seen hose diagrams for those. Go where the hissing is and try what I suggested. I am sure you will find a problem. Let me know what you find.

Hello I finally found the leak. The rubber dust cover has a hole in it and it's leaking air from the hole in the rubber boot. Is that something I can repair or patch it? Will it hold air? Or do I need to replace the struts?
