2004 Chevrolet Avalanche - Page 7 - Answered Questions & Fixed issues

I'm assuming that you mean it is very difficult to fill the gas tank at some gas stations. It often seems like it "kicks" if you look at it cross eyed. It's irritating, and some gas stations seem worse than others.The filler neck takes a sharp bend right by the opening, and reduces dramatically in diameter. Some pumps push out at higher volumes, and other pumps are more sensitive to the back-pressure, causing it to "kick" prematurely. The solution I found was to rotate the nozzle in the tank opening. If you turn it so the handle is at the 5 o'clock position it will sometimes work. Occasionally I've had to hold the nozzle upside down. Or just avoid that station.

Usually if the hydraulic brakes are the issue you would have the ABS and the regular brake warning light on at the same time.I would check the fluid level in the master cyl first. The master cylinder could be failing.

I'm assuming you have compression on those two cylinders and you have visually checked to see if the cylinders have spark and injector pulse.The code 449 is for a problem with the evap vent valve solenoid.Is there a vac hose near those cylinders that goes to the vapor canister or the evap solenoid ? Could be a vac leak.

here is a common problem with these trucks. The fuel tank evap canister vent becomes plugged. ( it's a sealed poly tank ) This can cause your fuel tank to be sucked in causing damage to the tank, Fuel level sensor ect. If you hear a sucking sound when you go to refuel its a good idea to have this checked. This happens all the time on oilfield trucks. In many cases the vent has been moved to a different location to prevent this from happening. many people have complained of this exact same thing on this exact same truck. If you are able to afford a good mechanic, He will know what to do if you print this answer or tell him this information. good luck... Tim

There should be two ports on the ac lines, one is bigger than the other to help prevent you from connecting to the wrong side of the compressor. The ports are covered with plastic caps.

Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

I suggest scanned the ABS module in order to know what fault codes is stored there, just with this code number knowed could send other details.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

Put it on fire. Fire will look after the reset and will flash it.

Its a 25amp circuit breaker marked "doors" in the instrument panel fuse box.

your battery in the remote needs to be replaced the car reads a chip in ththe remote and since its dead it cant read it.

each outlet has its own fuse they are in the fuse box under the hood

Probably a bad proportioning valve in the steering gear.

Check your starter Relay. It can be jumped from side to side with 1 battery jumper cable. It will spark, try venting the area if in an enclosed garage. If the motor spins, either the starter relay is bad or the signal from the ignition switch is not getting through.Jiggle the gearshift, check under the brake pedal lever for any switch operated by the brake pedal for being broken or knocked loose. There is a safety interlock which prevents starting if the gear is not in Park or neutral, some require the brake pedal to be pressed as well.Finally, your key has a computer chip and if it broke, the vehicle will not start. Try another set off keys if you have them. Also the burgular alarm may cut out the starter.

Could be the switch or the motor. Check with a test light for power to the switch. If you have power there the pull, the door panel unplug the connection to the moter and check for power to the connection by pressing the switch, repplace faulty part

Sounds like you have a defective universal joint or constant velocity joint in the drive line.

need scanner light comes on for reason thats what the codes are for they help see whats caused the fault to turn on light and it can be anything loose gas cap bad o2 sensor missfire 90% is loose gas cap rule of thumb if the way it drives does not change dont panic, if engine shakes n shudders get checked quick if fuel mileage is suffering get it checked n fixed soon burnin money!!

Electrical connection was loose following a routine maintenance check.

Try to grease the x-joint (u-joint) it could be tht its dry.
If its worn out you would thn get vibrations at certain speed.
Hope this helps!

Take your vehicle to your chev. truck dealer, they can send it in for repairs or they can also get you a re-furbished one at a low cost.

If it happens when you're driving straight ahead, may be a bad wheel bearing. If it happens while turning, probably a bad CV (constant velocity) joint.F
