Drain the oil and see if the coolant is in there. You have a cracked water jacket if it is. If it isn't you need to try and find where the coolant is leaking from.

we got a 03 h2 and had same problem took to dealer and they said on board air compressor went bad wanted 3000.00 dollars to fix,i said bull and went to strutmasters .com and got the coil spring replacements fixed it for about 300.00 bucks rides perfect and we dont have to worry about those damn rear airbag suspension any more,hope this helps someone

Same problem here! Did you fix it? If so, how?

There are wear indicators on the pads that squeal when you apply the brakes. You could look through the wheel and look to see if the rotor is smooth and groove free. The best way is to remove the wheels and visually check to see how much of the brake pad is left. If you are down to a 1/8 to 3/16th of an inch I would replace the pads.

can you be more specific?

near the first cylinder on the drivers side of the motor

Most overlooked cause for this concern is an extremely dirty factory (not aftermarket) air filter. Remove the factory air filter and blow out the debris still inside the box so the engine doesn't **** it in. Make sure all the air box tube clamps are tight and the MAF sensor is still plugged in good. Then try to start it without the air filter in. If it still does the same thing, unplug the MAF sensor and try to restart. If it starts only after the MAF was unplugged then you need a MAF sensor. Check these things and let me know what happens.I hope this info helps!~subyguru~

Why would you bother with a dealer after the warrantee runs out ?

Never heard of the 200,000 repair shops available,with better
results & cheaper than a dealer.

You can't ask what something costs
You do not have any idea what ,if any problems you may have

This does need to be scanned properly. It is in the air bag system which with the light on, is now disabled. The computer has sensed a problem with something in the circuit (i.e. belt buckles, clock spring, air bag modules themselves, etc.). If you want to get it scanned and let me know the codes, I can advise you from there.

Hi,

Please get back to us if you have any further query or else accept the solution.

check your abs sensors

1 of 2 things are going on, either the brake light switch is malfunctioning or the solenoid in the shifter assembly. when you apply the brake, you should hear a light click in the centre console allowing the shifter to release. if this is not heard, inspect the fuse block for burned fuses(unlikely but possible). next make sure your brake lights are working. if they are working it is perhaps the solenoid in the console itself. sometimes a little wd-40 works. but you need to get to it directly.

I'm afraid there is no solution for that.

****-lets be sure:

• Of your remaining die hard acquaintances, do any of them seem to be bleeding from the eyes?
• Have you heard remarks like, 'That must be what EVIL smells like' and 'OMG, I'm Blind'?
  
• Have you noticed sudden migrations of birds
• On clear days, do there always seem to be local cloud formations wherever you go?
• Can you fart 'Home on the range? On Key?

If you answered yes to any six of these five questions you may be suffering from Colon Breath. Though probably not as much as your family, coworkers and anyone downwind are suffering.

They say acceptance is the first step toward recovery.

However, in cases of CB, acceptance will be about it.

The best you can hope for is to try to alleviate the symptoms through diet, exercise and liberal amounts of Holy Water in the hope of achieving a state of remission, called SCB (Semi-Colon Breath).

If the 4WD service light comes on when you start your Hummer H2, it could indicate a problem with the four-wheel drive system. This warning light could indicate a problem with the transfer case, the drive shaft, the front or rear differential, or other components of the 4WD system. It is recommended to take your vehicle to a certified mechanic or a Hummer dealership for proper diagnosis and repair. The service light coming on could be a sign of a serious problem, and it is important to address it promptly to avoid further damage to your vehicle and ensure safe operation.
