I have a 2006 Hummer. I put it in 4 high during a snow storm, when I took it out, it still rides like it's in 4 high. The light indicates that it's back in all wheel drive, but it's difficult to make sharp turns, it whines when I make sharp turns. Someone told me to drive it backwards to unlock it but nothing seems to work. Please help.

SOURCE: The winshield wipers stopped working on my 2006

If the motor sounds like it's working, then it's a problem somewhere in the wiper transmission. As for the cost, that REALLY depends on who does the work. As for the warranty, that's probably going to depend on how much you tell them.

SOURCE: 2006 hummer h3 has a leak on passenger side under

My 06 was leaking during rain also. It turned out to be the sunroof. There are two drain tubes in the front of the sunroof that run the water down the corners to the ground and two drain tubes that drain water out the back corners. The water would seep around the glass, which is expected, but both of the tubes on the front of mine were plugged, and the water would overflow behind the dash and fill my floorboards. If my H3 was leaning to the left during a storm then the drivers side would be full of water. If leaning right, then the passenger side. I had to open sunroof and blow compressed air into the drain holes to clear them, but be careful, too much air will separate tubes from sunroof and then you will have to remove the inside paneling around sunroof to get to tubes and reconnect. You may only have one side plugged. you can test it by opening sunroof and pour a little water in the small catch pan in the front of the sunroof and see if it drains as expected (to the ground under the firewall on left AND right side). You can see the holes in each corner of catch pan to drain the water. Plug one with your finger, then the other to find the plugged side. Good luck!! Hope this helps!!

It doesn't take long to learn when and how to use your truck's 4WD system. Follow these steps and you'll feel confident about engaging the system the next time you need to get out of a slippery situation.

For a conventional system, where you can select 2WD or 4WD, the instructions refer to engaging 4WD. For trucks with permanent 4WD, they refer to locking the center differential.

Time Required: varies
Here's How:

1. Refer to your owner's manual to find out how to engage your truck's 4WD mechanism.
2. When driving in snow, mud, or just going off road, shift into 4WD when you get ready to leave solid ground. If you have lockable front hubs, lock them for those operations.
3. For severe conditions, use low range if available. Before shifting into low range you must either stop or slow down to at least 3 mph to prevent grinding gears.
4. When you return to normal conditions, shift out of 4WD or unlock the center differential. If the shifter doesn't want to move from 4WD or the differential lock stays engaged, don't panic, becaue the problem is normal and is caused by pressure on the gears.
   
   • Try backing in a straight line about 10 feet and try to move the shifter again.
     
   • If the shifter still won't move, try backing in an "S" pattern while trying to move the shifter.
5. If you have lockable hubs, don't forget to unlock them when you return to dry pavement.

1. Vehicles with permanent 4WD are set up for everyday driving, but not necessarily for maximum traction on slick surfaces. Engaging the differential lock increases the vehicle's traction capabilities.
2. Do not operate a locked 4WD on dry, hard surfaces. Doing that could cause damage to the driveshafts, differentials or transfer case.

It could be a wheel bearing fixing to go out. I would have a professional take a "listen" to it. Wheel bearings are quite common problems on most GM front wheel drive vehicles. They will cause the "whining" sound you are describing. You have to change the entire hub and bearing assembly if this is the problem. Labor is not too bad (about 1 hour) but the price of the hub assembly can range from $150 to $350 depending on which brand you use and who you buy it from.
