2004 envoy xuv tailgate problems
I also have a 2004 GMC XUV. My gate would go down but not swing open. In trying to fix it, the gate then refused to go to the flat position.I have removed the cover plate on the gate and found the one of the
solenoids loose from its mounting. Resetting the computer by disconnecting both battery leads and holding them together for ten seconds worked to restore function to the gate going flat, but the swing still does not work. I believe it is a bad solenoid or motor for the bottem left latch pin.
Where is the fuse for the master power window
There are different layouts for fuses depending on the model envoy you have and the engine size also. I can tell you this, it is always located in the rear fuse panel (see picture of location below) and the fuse will be marked DDR (drivers door module). It is in the number 10 position but like I said the layouts are different (nothing is simple). I went on and gave you a layout for the basic model of a 2005 so you can get the idea. I hope this helps you and good luck.
I HAVE THE SAME PROB AS GARCIAJORGE EXCEPT MY
There are two different ones. One for manual controls called blower motor resistor, and one for automatic controls (digital), called blower motor module. Look similar, but different.
My reduced power light keeps coming on in my 04
Check the vehicle for DTC'S - diagnostic trouble code's should be the first step in diagnosing this problem . But a tune - up not ! Reduced enging power is caused by a problem with the electronic throttle control . If you are not familiar with this ,your best bet would be to take to a qualified repair shop.
REDUCED ENGINE POWER: Refer to Powertrain Control Module Description in Engine Controls - 4.8L, 5.3L, and 6.0L
Throttle Actuator Control (TAC) Overview
The throttle actuator control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well.
The TAC system components include, but are not limited to the following:
• The accelerator pedal position (APP) sensors
• The throttle body
• The powertrain control module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position (TP)
Accelerator Pedal Position (APP) Sensor
The APP sensor is mounted on the accelerator pedal assembly. The APP is actually 2 individual APP sensors within 1 housing. There are 2 separate signal, low reference, and 5-volt reference circuits. APP sensor 1 voltage increases as the accelerator pedal is depressed. APP sensor 2 voltage decreases as the accelerator pedal is depressed.
One of these sensors could be sending conflicting data to the PCM - engine computer .
Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• Acceleration Limiting--The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode--The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode--The control module will turn off the throttle actuator.
• Forced Idle Mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
- Ignore accelerator pedal input.
• Engine Shutdown Mode--The control module will disable fuel and de-energize the throttle actuator.
Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.
My 2003 GMC Envoy (90K miles) seems to be stuck in
The transfer case is in low gear but the front axle actuator is not locking the front diff. This is an electronic problem and there will be C chassis codes generated. have the vehicle scanned for DTC's.
2004 gmc envoy remote doesn't work &key will not unlock it
You need to look up how to reprogram the Key FOB and it's a simple task, typically turning key on hitting lock button on Fob and repeating process until doors lock. You will have to get into the vehicle to do this of course. You may have to look up the exact process for that particular model.
Cant find where the mileage is stored
This is right from GMC service repair manual
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The base IPC contains a season odometer and a trip odometer. The uplevel IPC contains a season odometer and two trip odometers. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer.
The IPC calculates the mileage based on the vehicle speed signal circuit from the engine control module (ECM). The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers as requested by the activation of the Personalization button on the steering wheel controls.
