    So the dealer said it was the auto leveling control sol. valve in the air compressor is priced at over $1000 he said as well.....does this sound to be the problem? the compressor works at times so it just doesn't make sense to me....any ideas?

  • vanessammay Jun 11, 2010

    the compressor is not turning on at all now :( so i ordered a dual stage compressor with a conversion kit rather than messing around trying to find a solonoid valve for roughly the same least this way i will be sure it will fix the problem.

The hummer has air ride which means either it detected a leak or is losing pressure slowly possibly the pump gave out get to the nearest shop and have them look at all the connections and everything to determine what to do from there

Testimonial: "Thank you - I think it is leaking because she was riding low when it sat overnight and the compressor seems fine (it is new) so should be the air springs maybe? could be the ride height sensor? "

  • koltonserwe Jun 07, 2010

    Yeah, ride height sensor only if its not running low and the compressor is still running quite often, It could be the air springs I'm not to familiar with hummers but i would say its your best bet, the air springs or if it has air support bags too. Just in case thought make sure they do look at the connections!

    Does the compressor turn on when the vehicle is on a slop or if it on level ground alot?

U will need to have the system self tested by the dealer, they should quickly find the problem since they have the test gear to diag the issue, then replace the part that is defective yourself.

Air suspension hummer h2

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.

I was hit from behind and now the air suspension keeps coming on and it is starting to ride low what is it?

The accident probably caused the rear air suspension to leak and the compressor is having to run constanly...have it inspected for air leaks before you burn the compressor up. I hope this helps.
