Have you checked for codes?
this is not something they can do at the parts store because you need a professional scan-tool to pull hard/soft codes from the suspension module

additionally, are you dealing with the front or rear suspension issue?

Can you hear the compressor running for either?

Most of the time I find that there is a broke line or clogged vent

    HI Reisdos,

    Thank you for your response.

    We are dealing with the rear ais suspension.

    When you switch the ignition on the compressor cuts in and out for three cycles and then stops.

    The rear suspension is stuck at its lowest point and the air suspension service light is on..

    thanks for the quick reply

    with the compressor running and the suspension light on we can rule out a lot of things

    if you can give me the code I can help you further but my best gues right now is either a ruptured line.bag or faulty height sensor

    BTW... my name is Sean

Your vehicle is equip with air bag system. You probably experiencing an air lost due to air bags leaks or your leveling valve is exhausting air at the exhaust port. Here is what you do. Spray soap with water on spray bottle and spray around the air suspension area. when you see bubbles coming out that's the leaks. fix it. Good luck.

Replaced air bags on suspension now the bags will not inflate

You may have a leak in the lines or an issue with your compressor. my word of advice would be to check out Strutmasters. They have non air conversion kits for your vehicle that would take care of all of your air problems for good.

Air suspension wont inflat on hummer2 2003 rear suspension

what have you done to try to fix. 1 st I would jack the body up leaving the tires on the ground which will then activate the sensors that it is save to inflat. They have to be at least half way up. If that doesn't take it to the dealer and they will program the computer to do it.

Is there a reset button for the compressor-air suspension

When I replaced my air suspension bag it reinflated upon starting the Hummer. I did not have to reset anything. You may check the fuses in the event it ran so much to blow one and prevent the compressor from burning up.

What is wrong with my VIPER 5706v remote start alarm installation? 2002 Hummer H1 How it has been connected. On the alarm harness 6 pin connector Connected pin #1,2,3,5 to corresponding ones on the car changing the polarity of the parking light on the alarm by changing fuse position to the positive position. On the 10 pin connector Connected pin # 2,5,9 together to constant wire on the car Connected pin # 10 to 1st ignition on the car Connected pin # 4 to 2nd ignition on the car Connected pin # 8 to accessory on the car Connected pin # 6 to starter key side Connected pin # 7 to starter car side On the 24 pin connector Connected pin # 13 to ground Connected pin #14 to the factory alarm disarm output. - FACTORY ALARM DISARM OUTPUT. We connected the - FACTORY ALARM DISARM OUTPUT through a relay to the - Factory Alarm Disarm wire. At the same time, using a relay and 2 diodes we have connected the Viper alarm - unlock output to the + door unlock wire and the - factory disarm wire, so the factory disarm wire is pulsed at the same time as the unlock wire. Connected pin # 20 to brake wire on the car Connected either pin 15 negative trigger or pin 18 positive trigger to door trigger out on the car Connected pin #22 via a relay to the wait to start glow plus light wire. The wiring diagram supplied by Direct Wire shows the Hummer H1 2002 with an Orange + wait to start wire, therefore the relay was used to reverse polarity. Connected pin #24 to the factory alarm arm wire. 3 pin connector door locks As the DirectWire wiring diagram shows the 2002 Hummer H1 having reverse polarity door lock system, we have used 2 relays Pin # 1 Pin # 3
