Hello;
The parking brake cables may be stretched and in need of adjustment. Follow the cables along to a nut. Then you can tighten the adjusters up on both sides until you have the proper tension. Also make certain none of the brackets are bent or broken that the cables ride through.
Thanks;

Pull the actual seat from the middle and lift up, then push the back part down...the middle part (2nd row) will lay flat.

can you hear the fuel pump running in the gas tank when you first turn the key to the run position?

Have you never had a problem like that, since you started driving? Start testing things-- to find a problem Is the battery dead,old,worn out? Have it tested Test the starter & solenoid Examine & test the battery cables & many other items effecting the starting system Won't Crank (turn over)? or Won't Start? Won't Start check for fuel pressure,spark,injector pulse & so on

Check all your fuses,and if you don't have any bad fuses then make sure the positive wire to the electrical center and starter are very clean.

could be anything from the weird to the sublime so i couldnt evan hope to tell you unless i had the vehicle in front of me sorry

Sugerinimo's idea is good but I good not get it too work.. Well, this can be easier or a bit harder. Mine was harder. You are stuck on the secondary tire lock. There is a process in your manual that involves lowering the tire as far as it goes with the secondary lock, then placing your tire jack under the center of the tire holder and jack it back up until its tight to the frame - this should release the secondary lock. In my case this did not work. Plan B, is grab a 15 mm socket, small extension and ratchet. Lower the tire as far as it goes. Locate the 15mm bolt that attaches the tire hanger to the frame, undo the bolt, the hanger is then swinging from the back, lift up the tire and bracket and it will fall off. be careful the tire is heavy.
Next on the top of the tire you will see a rubber cover the secondary lock slides into. Pull down the boot. You will see two holes along the bottom on the opposite side to the crank. Turn the bottom part of the lock. If you look in the holes you can see where the catch is. Take a slot screw driver and hammer, line up the catch and tap it back in.
The secondary lock is now free.
Remember when reinstalling the bolt on the frame to use some locktite.

It sounds like the connection to your dash gage may have gone lose do to everyday vibration. If everything was running fine without any check engine or service engine soon, then it's your dash gage. Before your start your truck and the key'sare in the run possition, your gages should move up then down checking it's self. Keep a eye on that. Good luck. easy fix dubble check connection. 

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.

I have worked at a chevrolet dealer for 12 years and have probably replaced a few hundred of these clusters. the speedometer portion of the cluster always goes out, I have had very few speed sensors go out, and when they do the check engine light will come on and the trans. won't shift, if the new cluster is too expensive they are easy to replace if you just buy it outright, you can also get a wrecking yard cluster your miles just won't match

Hello, this problem is due to a failing stepper motor. The stepper motor is the motor behind the gauge that controls the movement of the needle. When a stepper motor begins to go out it will cause the gauge needle to stick, skip around, stay at zero or max out on the gauge. The only way to fix the problem is to replace the stepper motor with a new one. While replacing one motor it is best to go ahead and replace them all as the others will go out in time as well. Your cluster will have one motor for each gauge. Here's a link to a page showing exactly how to replace a GM stepper motor and where to get the correct parts to do the job!

I'm going to assume you checked the fuses, and say that the display panel will have to be replaced. On these the display is all one piece, and when one gage goes out it effects the whole thing. Some of these display panels had in line fuses on the inside circuitry, so you may be able to pull the display and change the fuse. Others were built as a sealed unit and cannot be taken apart.

Hello, Last year General Motors lost a lawsuit about the instrument panels in 2002 to 2005 trucks. The following website contains all the information about this lawsuit settlement.

This impacts the entire gauge cluster in your vehicle.
I have the same year and model as yours and my speedo is never accurate and the tach always read 6000.
The issue is the metal bearings that the gauge meter movements use. The bearings are getting dry which impedes the meter movement.

oil ressure sending unit needs to be replaced. Most are located near or at the oil filter mount location.

Tilt steering down,, turn on key shift to low gear,, grab front of the dash where the 2 pieces meet, top right side ,,,and pull it will come out,,, no bolt just presure clips,,, very simple,, the light switches will need to be unpluged when you get it loose to take it all the way out,,,to take the guage cluster out ,,,some have 4 ,,,7 mm bolts on the corners,,,some have star type bolts,,, then unclip the shift indicator line in the center of the cluster,,,"looks like fishing line with a clip on the end" and pull out the cluster,,,,also be sure to put the indicator back in th same spot or your PRND321 will off

Did the engine just quit going down the road? or was it parked and then would not start? Did it have fuel before you replaced the filter? Did you check all the fuses in the fuse box. I think 2 of the fuses is marked ECM, check both Fuel pump relay? swap it with another relay in the fuse box. You should hear the pump come on for 2 seconds when you turn the key on, do you? If not as you are cranking the engine have someone rap on the bottom of the fuel tank with a mallet or block of wood, or hammer and see of the pump will run. If that gets it running, the pump is bad and will need replacement.
