98 BUICK REGAL: GRINDING OR RUBBING NOISE WHILE TURNING

ONLY WHEN A PASSENGER IS PRESENT IN THE REAR SEAT AND I TURN IN EITHER DIRECTION OR GO OVER A GRADE CHANGE LIKE AN INTERSECTION, THERE IS A RUBBING OR GRINDING NOISE THAT SEEMS TO BE COMING FROM THE REAR HALF OF THE VEHICLE THAT APPROXIMATES THE REVOLUTION OF THE WHEEL. I AM STUMPED.

It's something in the back wheels making the noise. Not to many parts to make that when rolling. So check the wheel bearing it's super easy. Jack the car rear tires up to clear the ground doing that. Now shake the tire back and forth to feel any movement. If it moves any little it's most likely a bad wheel bearing. Remove Nd replace. If it's rubbing then remove the tire and look for scratches on the caliper rubbing the wheel inside. Or shocks. If you don't know what your doing goto a shop and let them inspect it for you. Also if you have a tire that is wearing tread off the sides that will be a clue which side it is.

SOURCE: signal bulb on 2003 buick regal

To change front turn signal –
open the hood; look in back of headlight; two white clips; pull straight up, and then whole headlight comes out including turn signal; it is all one unit; remove rubber cover, then you take bulb out of unit. Mechanism that bulb fits in will need to be turned clockwise (looking from the front) and pulled to get it out of the larger unit holding all lights. Be sure and put rubber cover back on before re-inserting the two white clips.

Check for leaks in the brake lines and calipers or brake cylinders. If leaking have it repaired right away its not safe. Change the brake fluid, take the old fluid out add new fluid or have it professionally done.

The fluid in the versa trak AWD in the rear is old and needs to be drained and refilled. After you drain and refill it, make a bunch of sharp left and right hand turns, then drive it for 10 minutes. Drain and refill it for the second time and problem solved. Use only versa trak fluid available at any GM dealership. There is TSB on this now at the Buick dealership.

How to disable passenger side air bags, for children and small passengers


You don't have that smart stuff for weight. You can't turn it off. If you don't think they should be in front, because of age or height. Put them in back. I haven't seen a van yet that had this option.

Why is the Air Bag Light on On my 2005 Nissan Quest


If you are asking its purpose: it is to let you know whether or not the passenger seat frontal bag is deployed to trigger in case of a collision. Frontal/face-directed airbags have no reason or need to "fire" in the case of an empty seat; and every reason, safety-wise, not to fire into a seat occcupied by a child (a person below a minimal, safety related threshold passenter weight...lest the impact injure or kill). That is why children and similarly vulnerable smaller/frailer people belong behind the front seatbacks in a rear seat if present.

On the other hand, if the driver (who for obvious reason does not merit his own light) notices that the "air bag off" indicator in front of the passenger seat does not extinguish (or "bag on" light does not activate) when an adult comes aboard...that is an indication to driver and passenger alike that the bag might not fire in the event of a collision.

Everything said above also applies to parcels placed in the front passenger seat...a practice that has largely been superseded by trunk and backseat placement of parcels (placement of anything on the so-called "package deck" (Ford's term for rear window ledge) being "not" recommended).

For readers with owner manuals, this info is explained for their particular vehicle models.

Turn off passenger airbag


Always refer to your owners manual, but if there is no key switch in the glove box, you probably have the sensor system which monitors weight in the passenger seat. If you have more than 30lbs in the seat the airbag is "on" and the sensors are activated. Otherwise the passenger side is off if the seat is empty.

2008 Buick Enclave; front passenger, no power to window and lock controls, and no power to passenger side mirror. Additionally, passenger heated seats do not operate. From driver seat control, I cannot...


Do you know anything about automotive electronic's ? Serial data Communication network ? Electronic module's inside the vehicle doors , communicate commands ! No relay ,no fuse .
If the passenger mirror is selected and a direction switch is activated, the DDM sends a serial data message to the PDS indicating that the passenger mirror was selected and the direction to be commanded. The PDS will then supply battery voltage and ground to the appropriate control circuits for the direction selected.
DDM - driver's door module

Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door

Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Body control module (BCM)
• Passenger door module (PDM)
• Rear door power window switches
• Power window motors in each of the doors (circuit breaker protected)

Your best bet , take it to a qualified repair shop that has a diagnostic scanner that can pull code's an view input data form these systems . There is one circuit breaker for the window's an fuse's for the lock's . I would think a data network problem . But that would be a guess , without testing anything is possible on these .

I have a 2008 Chevrolet Silverado 1500, extended cab, automatic truck.......PROBLEM, the drivers side has a power seat, it will not move in any direction and the passenger side front and rear power windows...


How to diagnose this problem ? Viewing wiring diagrams to see what all is invovled in these electrical circuit's , check power supply's an ground connection's using a DMM - digital multimeter !
What type power seat's ? does it have memory ,heated an cooled etc ?
Power Seats System Description and Operation
There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function. While the passenger has 8-way power seats with heat and optional cool function. For the driver memory seat operation, refer to Memory Seats Description and Operation. Power seats without memory are completely controlled through the power seat switch. Battery voltage is supplied to the power seat switch through the power seat circuit breaker. While the seat adjuster switches are in an inactive state the switch contacts are closed to the power seat switch ground circuit. When a power seat switch is pressed to an active state the switch contact is closed to the battery voltage supply circuit. Each seat adjuster motor is controlled by the power seat switch through 2 motor control circuits. The seat adjuster motors are bidirectional and the direction of adjuster motor rotation is determined by which of the adjuster motor control circuits is switched to battery voltage while the other remains grounded.

If it has memory seat's there is a control module !
Battery voltage is supplied to the driver seat module through a 25 A circuit breaker. The driver seat module supplies the seat adjuster switch assembly with a battery positive reference voltage. While the seat adjuster switches are in an inactive state the switch contacts are closed to the adjuster switch common circuit.
Both right side windows have a seperate power supply from the left side window's ,has RT DOORS circuit breaker CB1 - 25amp. location left instrument panel fuse block . Circuit breaker's very rarely fail .Do the door lock's work on that side of the vehicle ? The windows won't work with their own switche's ?
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)
Check PDM fuse 4 15 amp ,this supply's B+ voltage to the DOORLOCK/WINDOW switch passenger side . Check for broken wires inside the flex boot from the body to the passenger door .

I have a 2003 Ford Excursion Limited: I had the passenger side rear seat in the down position, which requires the bottom part of the seat to be lifted up against that back side of the front passenger...


I just encountered this problem with my 2000 Ford Excursion. After fighting with it for several hours I realized that the section of the seat that is facing up towards the roof of the vehicle was applying pressure to the back of the seat that was facing down and preventing the back of the seat from coming up when I pulled the lever. So, the next time I pushed the seat up that is facing the roof while I pulled the lever and this resovled my problem.

Can you turn the passenger airbag off on the 2003 Ford Sport Trac. If so where is the switch


No you can not turn it off. Any vehicle that has a rear seat will not have the option to turn off the passenger air bag. I guess the reasoning here is you can sit in the rear seat instead of front if you do not want to be exposed to the air bag.
