Replace your battery terminals. It completly worked for me on my 2005 uplander. I was at the point of jumping the battery daily because it would'nt hold a charge. As soon as I changed the terminals (I'll add that they were the strangest terminals I've ever seen) and got a new battery, it starts and holds a charge like a champ! Hope this helps.

Check battery cables for tightness.check drive belt on alternator make sure its not slipping. check alternator wires fuse+ fuse link. if all looks good problem in the pcm and bcm.they are the vital parts of charging system.they are tied in with alternator field terminal.

Your idle air controller valve on the throttle body may be no good.if the idle speed drops too low,the alternator will have no output,and the steering rack which on the uplander i believe is electric like the cobalt,will not put out enough drive.if you shut off the vehicle,but leave the ignition on,and it has an electric rack,the steering should still work.if it doesnt it is hydraulic assist.if the idle speed goes to say 400 rpm,the power steering will not work .when this happens,check the tachometer what the rpm is...

How do I remove the center console where the heater control switches are located on a 2006 Pt Cruiser GT


DESCRIPTION A manual temperature control (MTC) single zone type heating-A/C system or a manually controlled heater-only system is standard equipment on this model, depending on market.
To maintain the performance level of the heating, ventilation and air conditioning (HVAC) system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or A/C condenser will reduce the performance of the A/C and engine cooling systems.
The engine cooling system includes the radiator, thermostat, radiator hoses and the engine coolant pump. Refer to 7 - Cooling for more information before opening or attempting any service to the engine cooling system.

All vehicles are equipped with a common heater, ventilation and air conditioning (HVAC) housing (1). The heating-A/C system combines heating, ventilating and A/C (if equipped) capabilities in a single HVAC housing mounted within the passenger compartment beneath the instrument panel. The HVAC housing includes:
  1. Mode-air doors (2)
  2. A/C evaporator (A/C system only) (3)
  3. Recirculation-air door and actuator (A/C system only) (4)
  4. Blower motor (5)
  5. Mode control cable (6)
  6. Temperature control cable (7)
  7. Heater core (8)
  8. Blend-air door (9)
On heater-only systems, the A/C evaporator is omitted from the HVAC housing and is replaced with an air restrictor plate.
Based upon the system mode selected, conditioned air can exit the standard heater-only or optional heater-A/C housing through one or a combination of the three main housing outlets: defrost, panel or floor. The defrost and panel outlets are located on the top of the HVAC air distribution housing and the floor outlets are located on each side of the distribution housing. Once the conditioned air exits the HVAC housing, it is further directed through molded plastic ducts to the various outlets within the vehicle interior. These outlets and their locations are as follows:
  1. Defroster Outlet- A single large defroster outlet is located in the center of the instrument panel top cover, near the base of the windshield.
  2. Side Window Demister Outlets- There are two side window demister outlets, one is located at each outboard end of the instrument panel top cover, near the belt line at the A-pillars.
  3. Panel Outlets- There are four panel outlets in the instrument panel, one located near each outboard end of the instrument panel facing the rear of the vehicle and two located near the top of the instrument panel center bezel.
  4. Front Floor Outlets- There are two front floor outlets, one located on each side of the center tunnel near the dash panel.
  5. Rear Floor Outlets- There are two rear floor outlets, one located on each side of the floor panel center tunnel near the front of each rear seat foot well.
  6. REMOVAL
    WARNING: Disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.


    NOTE: Illustration shown with instrument panel removed for clarity. (Refer to 23 - Body/Instrument Panel/BEZEL, Instrument Panel - Removal).(Refer to 24 - Heating and Air Conditioning/Controls/CONTROL, A/C and Heater - Removal).(Refer to 23 - Body/Instrument Panel/COVER, Steering Column Opening - Removal). 5. Remove the screw (1) that secures the temperature control cable (2) to the left side of the HVAC air distribution housing (3). 6. Disconnect the temperature control cable from the blend door pivot lever (4) and remove the cable from the vehicle.

I have a 2006 Pontiac torrento and my steering wheel gets hard. not all the time it dos it 1 a day at least Dont know whats the problem i have try to check for the fuled but no luck plz help


Your vehicle has electric power steering . GM had a recall on some of it's vehicle .
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, nor the EPS motor are serviced separately from each other or from the steering column. Ant EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.

Charging System Failure
Refer to Charging System Description and Operation

Electrical Power Management (EPM) Overview
The EPM system is designed to monitor and control the charging system and send diagnostic messages to alert the driver of possible problems with the battery and generator. This EPM system primarily utilizes existing on-board computer capability to maximize the effectiveness of the generator, to manage the load, improve battery state-of-charge (SOC) and life, and minimize the system's impact on fuel economy. The EPM system performs three functions:
• It monitors the battery voltage and estimates the battery condition.
• It takes corrective actions by adjusting the regulated voltage.
• It performs diagnostics and driver notification.
The battery's condition is estimated during key-off and during key-on. During key-off the SOC of the battery is determined by measuring the open-circuit voltage. The SOC is a function of the acid concentration and the internal resistance of the battery, and is estimated by reading the battery open circuit voltage when the battery has been at rest for several hours.
The SOC can be used as a diagnostic tool to tell the customer or the dealer the condition of the battery. Throughout key-on the algorithm continuously estimates SOC based on adjusted net amp hours, battery capacity, initial SOC, and temperature.
While running, the battery's degree of discharge is primarily determined by a battery current sensor, which is integrated to obtain net amp hours.
In addition, the EPM function is designed to perform regulated voltage control (RVC) to improve battery SOC, battery life, and fuel economy. This is accomplished by using knowledge of the battery's SOC and temperature to set the charging voltage to an optimum battery voltage level for recharging without detriment to battery life.
The Charging System Description and Operation is divided into 3 sections. The first section describes the charging system components and their integration into the EPM. The second section describes charging system operation. The third section describes the instrument panel cluster operation of the charge indicator, driver information center messages and voltmeter operation.

Charging System Failure
The BCM and the ECM/PCM will send a class 2 message to the IPC for the CHARGING SYSTEM FAILURE message to be displayed. It is commanded ON when a charging system DTC is a current DTC. The message is turned off when the conditions for clearing the DTC have been met.

You need to have a full vehicle scan done. Not just engine code's . An to do this you need a professional scan tool , not auto zone or advance etc.. Your best bet , take it to a qualified repair shop.

Your charging system is computer controlled . Do you know what DTC'S - diagnostic trouble code's are ? This are all associated with the charging system inone way or another .
