2006 hummer h3 headlights wont turn off!

Ive changed the relay and the headlight switch on the dash .. still wont turn off headlights ? Just changing parts won't fix it , need to test . Hooking up a professional scan tool , one that can read codes in the BCM - body control module is the way to start to find the problem . Then familiarize yourself with how they work. Headlamps Major components of this system are the body control module (BCM), headlamp relay, beam select relay, ambient light sensor, headlamp and panel dimmer switch, turn signal/multifunction switch, park brake switch, and the low and high beam headlamps. The headlamps may be turned ON in 2 different ways. First, when the driver places the headlamp switch in the ON position, normal operation occurs. Second, when the headlamp switch is placed in the AUTO position, automatic lamp control (ALC) operation occurs. During ALC control, the headlamps will be OFF in daylight conditions or in low/high beam operation in low light conditions. The headlamp relay receives battery positive voltage directly from the battery. The BCM supplies a ground signal to the headlamp relay for normal headlight operation. The BCM also supplies voltage to the beam select relay coil for high beam headlight operation. When the driver places the headlamp switch in the ON position and the dimmer switch is in the low beam position, the headlamp relay supplies current flow through the left and right low beam headlamp fuses to both low and high beam headlamps. Both low beam headlights are grounded through the beam select relay. When activated, the dimmer switch sends a ground signal to the BCM in the high beam position and a momentary ground signal in the flash-to-pass (FTP) position from G106. The BCM then energizes the beam select relay which switches the headlamp grounds from the low beam headlight bulbs to the high beam headlight bulbs illuminating the high beam headlights. With the headlights in the low beam position, the high beams may be momentarily turned ON or flashed by activating the FTP portion of the switch. The instrument panel cluster (IPC) illuminates the high beam indicator when the BCM detects that the high beams are requested. The IPC receives a class 2 message from the BCM requesting illumination. The Headlamps On at Exit and Perimeter Lighting modes can be adjusted using the steering wheel controls to select the function as displayed in the driver information center (DIC). The Headlamps On at Exit selection will allow the driver to customize the period of time that the headlamps remain illuminated upon exiting the vehicle. This period can be adjusted from 0-180 seconds. The Perimeter Lighting feature allows the driver to select if they want the headlamps and backup lamps to illuminate when the door UNLOCK button on the key fob is activated. This feature can be turned ON or OFF by using the DIC steering wheel control buttons. DTC B2575 Headlamp Control Circuit Circuit Description When the body control module (BCM) senses a request for headlamp or daytime running lamp (DRL) illumination, the BCM sends a ground signal to the headlamp relay through the low beam headlamp relay control circuit. The headlamp relay will illuminate the low beam headlamps. Install a scan tool. Turn ON the ignition, with the engine OFF. With a scan tool, command the headlamps ON and OFF. Does the headlamp relay turn ON and OFF with each command? Do you know what bi-directional control means ? Need a professional scan tool to do these type of test . DTC B2602: Daytime Running Lamp Control Circuit Low or Open DTC B2603: Daytime Running Lamp Control Circuit High Without this type of info. from service repair manual an using a scan tool your missing the big picture .

Head lights wont turn off 06 h3 hummer

If you pull the headlamp relay in under hood fuse box, that should kill the headlamps until you figure out the problem? I don't know if relay could be faulty? I'd want to check relay wiring circuit for ground? Your bcm grounds the coil side of headlamp relay in order to energize. I'm not saying bcm has a problem? The bcm receives input from headlamp/dimmer switch telling it the headlamp relay should be grounded. You might check for bcm or communication trouble codes. 26312760-dtx0paaksp2dudcj4ee0acfc-2-0.jpg

My 2006 H3 has water leaking into drivers side floor

While H3 is parked on driveway, driver floor mat is removed, and steering turned all the way right to expose splash area, pressure hose the front left steering splash area behind left tire while another person feels with their hands to determine where water is entering. If the leak is beneath, it would only enter when you go through flooded area. When it rains, the water constantly splashes behind the tires, which is an area source for water to enter the driver area while the vehicle is in motion during rain condition. If you live in snow area, they use salt to keep roads clear of snow. Salty water is highly corrosive to exposed steel. In the summer or fall season before snow begins, you steam jet pressure clean the underside, then inspect for any area where undercoating had come off. Take primer spray paint and cover these exposed areas with at least 3 coats of primer paint, or rubber sealant spray. f023abf2-11ec-4e1e-a889-edf79c334876.jpg

2006 Hummer h3 ...it only shows 3 positions for the 4x4 a 4with a up arrow a 4 high with a lock and a 4 low with a lock does this mean the vehicle is always in 4wheel drive

The Borg Warner (BW) model 4493/4494 NR4 transfer case is a 2-speed, full-time 4WD, transfer case. The transfer case has an external planetary type differential, which has 2 different sets of pinion gears. The planetary differential provides a 40/60 torque split front/rear full-time. This means the front and rear propeller shafts are constantly being driven for maximum traction in all conditions. A high/low planetary carrier assembly provides the high and low ranges, which is a 6-pinion gear, sun gear, and annulus gear arrangement, giving a 2.64 low range reduction ratio in the BW 4493 and a 4:1 ratio in the BW 4494.

Hummer h3 2006. Had a sunroof module replaced and now sunroof slides back only part way. Pushing close button causes roof to close and continue automatically to pop up position. Will only close by

Sounds like the tracks are out of time with the motor. I would take it back to the mechanic that changed the module.

06 hummer displays a padlock and will not start with key

Your security system has locked u out, do a pass key reset, if this does not work then u will need the dealer to test the system for a failed part.

PASSKEY LOCKOUT RESET GM (yes it is GM) CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.

06 hummer h3 making loud. High pitch squeling

If the squealing is coming from under the hood while the engine in running then it could be a number of things such as an idler bearing, water pump bearing, or possibly an air conditioner or alternator bearing. Other possibilities are belts that are worn or have gotten wed from a bad water pump or have loosened up because of a bad belt tensioner. Take a long bar and touch each area that seems to be making the noise. If you can feel the vibration or hear the squeal when you touch the area, then you found your noise.
