2003 Chevrolet Suburban 1500 - Answered Questions & Fixed issues
My 2005 suburban AC is blowing hot air
If you touched any of the A/C controls within 45 seconds of starting your Suburban (after the battery change), you messed up the 'calibration mode' of the HVAC.
Pull the HVAC fuse (10amp) under the hood, and pull the two adjacent fuses (30 and 10amp) under the dash listed as 'climate control' in the manual.
Push the fuses back in, restart your car, but DONT TOUCH ANY of the A/C controls for 90 seconds.
I bet the A/C starts working again normally.
I have a 2004 suburban with power fold, heat,
I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both
solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from

2 problems...Service 4WD...(already replaced switch module!), and won't start with ~1/2 tank gas or less!
Do you know how to do scan tool diagnostic's ? Checking DTC'S - diagnostic trouble codes , viewing input data to the computers on the vehicle . The fuel sending unit is located inside the fuel tank ,it is a input to the PCM - engine computer . The PCM use's this fuel level info . to be able to conduct testing procedures for the evaporative emission system.
The Evaporative Emission Control System (EVAP) is used to prevent gasoline vapors from escaping into the atmosphere from the fuel tank and fuel system. The EVAP system usually requires no maintenance, but faults can turn on the Check Engine light and prevent a vehicle from passing an OBD II plug-in emissions test..
Shorted sensors can cause all kind of problems .including bring down the five volt reference circuit inside the PCM . Also checking for DTC'S in the 4X4 control module should have been done before replacing parts . Your best bet ,take it to a qualified repair shop.
Do you know which transfercase your vehicle has ?
The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel.
The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel.
Just replacing parts is not the way to a fix . Both systems can set a number of DTC'S
DTC B0790
DTC B2725
DTC C0306
DTC C0327
DTC C0329
DTC C0359
DTC C0550

DTC C0305

DTC C0321

DTC C0359
DTC C0374

Do yourself a favor ,have a qualified repair shop diagnose the problem . An you can't just replace the 4X4 control module an expect it to work .It needs to be programmed .

2003 suburban cd player will not load
Internal problem with the radio. Common problem. The mechanism the sucks in the cd is supposed to lower inside the radio but isn't working properly.
Power light on A/C Control flashing.
First things first...your vehicle will register fault codes for assisting in the trouble shooting of some system failures (usually emissions related faults.) This system is called OBDII.
Auto zone used to provide free reading of your vehicles on board computers in the hopes that you will purchase the required repair parts there.
When you retrieve the codes either by the assistance of a parts store or by purchasing a ODBII Code reader you will have a place to start your investigation.
PS: Your owner manual may also help to identify the meaning of tell tale lamps on your dash cluster.
Follow the link below for another possible fix for your flashing light:

Gm trouble code list
P0140 - 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
The causes for a P0140 code are few and unless the wire/s has been damaged, replacing the sensor is usually the smartest thing to do.
Speedometer not working
There are a couple of things to investigate before condemning the speedometer.
1) Does the cruise control still work?
2) Is the check engine light on?
If the cruise control does not work and or the check engine light is on, you can take your vehicle to your local Auto Zone or Advanced Auto Parts and they will scan for fault codes at no cost to you.
Write the codes down and reply back to me and we can work on the issue.
Let me know.

Hello and welcome. the problem is with the dash cluster. the dash cluster will have to be replaced and reprogrammed. there is a special warranty for these dash clusters. gm will cover the repairs up to 80,000 miles
This special coverage covers the condition described above for a period of 7 years or 70,000 miles (110,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the instrument panel cluster after the condition has been verified. The repairs will be made at no charge to the customer.
