SOURCE: 97 gmc sierra won't go into 4x4. Electronic

Take the front axle actuator out of the axle. Plug it back in and have some one push the 4x4 button. The actuator should move, it's a liniar motor. If it doesn't then the actuator is bad or there is a wiring problem. If it does there is a problem in your front diff or some where else in the system.
I'd take a guess and say it's the front actuator.

SOURCE: 2005 GMC Sierra 1500 - heater blows, but only cold air

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."

you will need a wiring diagram to find problem, first make sure the power feed circuit is good, use a test light or volt meter will be better, some times cigarette lighter circuit and o.b.d.II feed share same circuit. also look at signal circuit. it should b between 5*7 volts.

What does mil cmd fail mean?


MIL is your malfunction indicator lamp, (check engine light)

CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer

check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.

Failed emissions test


First step is to have the code or codes read.If the "check engine light" is on there will be a reason and should be a code or codes to be read.Once you have the codes,you can determine the correction needed to get that "check engine light" out and a valid emissions test completed.Get back to us with the codes found.

Emmissions failed due to the following. OBD Connector Integrity - malfunction indicator light (MIL) status This is for a 2000 chevy lumina


MIL status is error codes, but usually for pre 1995 vehicles. If you check engine light was on, then it would not pass emmissions. Since your vehicle is a 2000, I would suggest you take it by an autoparts store and have them read your error codes before you try to reset them. Make sure you write them down in the order they come off their scanner.

Yu can usually clear error codes by disconnecting your battery.

A SCAN TOOL WILL TELL YOU WHAT CYLINDERS MISFIRING.THATS QUICK WAY TO CHECK.CHANGE FUEL FILTER AND CLEAN FUEL INJECTORS BY FILLING GAS TANK AND PUTTING A BOTTLE SEA FOAM IN TANK.MISFIRING LACK OF POWER AND STUMBLING ON ACCELERATION MOST TIME CLOGGED FUEL INJECTORS WILL CAUSE THOSE PROBLEMS.

I have a 2005 Chrysler 300C hemi and the malfunction indicator light came on. What should I do?


The malfunction indicator light(mil) can come on, if there is a problem in
1 or more of the vehicle's systems. Such as fuel/electrical or emissions.
To isolate the problem, the car needs to be scanned with an OBD II
(onboard diagnostic)scanner. You can stop by any of the auto parts chain store's(advance/auto zone/napa)and they will scan it for free.
Hope this helps.

Did not pass state inspection (vehicle)


First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.
