power seat 1996 Chevy LuminaI have a driver side power seat that will track forward but not back. Is that the motor or is that the switch?

RESPONSE

It could be either of the two or the wiring harness and or connection at the power seat. May also be an obstruction in the way causing it to bind.  You will need to use a multi-meter and do a little testing. Check for power being applied to the motor when the seat will not move. If power is being applied then the motor is bad or there is something causing it to bind. Remove the motor and test it again. If no power is getting to the motor, trace the wiring back to the switch and repair as needed.

2001 Chevy CavilierI just replaced my upstream 02 sensor and have not replaced the downstream 02 sensor just yet to see if I only needed one and I replaced upstream and ran diagnostic and the upstream that I just replaced is erroring out. Any advice?

RESPONSE

Check your wiring harness and the connections. Provide the engine trouble code you are dealing with for more information.

1986-chevy-camaroI have a Camaro Berlinetta.  I just notice my passenger and rear floorboards are wet when I left up the mats. Mats are dry on top but wet underneath. Sides are dry.  I don’t smell any coolant. The car sits on level ground. What could cause the leaking?

 

RESPONSE

Still could be heater core leaking. Check the coolant level periodically to determine if you are loosing any coolant. The seals around the door may be leaking. Spray with water hose and see if any gets in.

Another thought may be the evaporator core drain plug is clogged.

RESPONSE

A warn hub bearing assembly.

Why does the motor shake and knock only when its idling

RESPONSE

A knock at idle that goes away when the engine rpm is increased is caused from main connecting rod bearing failure.

A knock that gets louder as the engine rpms are increased is caused by rod bearing failure.

Blower Motor 2008 Chevy ImpalaThe blower motor in my 2008 Chevy impala 3.5 engine cuts out completely. A few swift kicks under the glove box usually gets it going again. There are no strange noises,
all speeds work, and the temperature adjusts as it should.

RESPONSE

  1. Check the connections at the blower motor
  2. Confirm battery negative and positive when the blower is not working
  3. Replace blower motor

The kicking under the dash is probably enough to jar the internal brushes in the motor just enough to get it to make sufficient contact. This allows the motor to operate until the next time. Replacing the blower motor would be the fix.

  • Remove the right closeout insulator.
  • Disconnect the blower motor electrical connector.

2002 Chevy SilveradoWhen my 2002 Cheverolet Silverado 1500 4WD Ext Cab LS is moving the front end rattle badly. When i put in 4wd the rattle is quite a bit quieter however the 4wd does not engage it just makes a clicking sound.  I Know the front end is out of alignment and needs to be realigned , but the rattle noise and 4wd malfunction is new. What could be the problem or problems?

RESPONSE

There are many possibilities when it comes to a rattle noise or any noise for that mater. Could be something loose or worn. A hub bearing assembly going out could be at fault. Maybe an axle-shaft or universal joint going bad. Could be internal in the front differential. Possible 4WD actuator issue.

Front Drive Axle Description and Operation

Selectable Four Wheel Drive (S4WD) Front Axle Description and Operation

The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:

    • Differential Carrier Housing
    • Differential Assembly
    • Output Shafts (Left and Right Side)
    • Inner Axle Shaft Housing
    • Inner Axle Shaft (Right Side)
    • Clutch Fork
    • Clutch Fork Sleeve
    • Electric Motor Actuator

The front axle on Selectable Four Wheel Drive model vehicles uses a central disconnect feature in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across the inner axle shaft and the clutch fork shaft and locks the two shafts together. The locking of the two shafts allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The drive axles are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

Full-Time Four Wheel Drive (F4WD) Front Axle Description and Operation

The Full-Time Four Wheel Drive (F4WD) Front Axle consist of the following components:

    • Differential Carrier Housing
    • Differential Assembly
    • Output Shaft (Left Side)
    • Inner Axle Shaft Housing
    • Inner Axle Shaft (Right Side)

The front axle on Full-Time Four Wheel Drive model vehicles does not have a central disconnect feature in order to engage and disengage the front axle. The left and right axle shafts are connected directly to the differential case assembly. This allows the axle shafts and the propeller shaft to spin continuously. The transfer case controls the amount of torque applied to the front axle. The remaining components are the same as the selectable four wheel drive axle.
