take your vehicle to Autozone they can check the batter for free with the batter in the truck they can also check the altanitor, Most likely you have a dead cell in the battery-if not change out the Altinorter

I would definitely replace/check the alternator, and check on that first of all. It may have affected the computer, giving false/bad ground/voltage readings. Hopefully it didn't significantly hurt the ECU! (Computer)

  1. Open the hood.
  2. Remove the park/turn signal lamp assembly.
  3. Remove the headlamp retainer pins.
  4. Pull out the headlamp assembly in order to access the electrical connector.
  5. Disconnect the electrical connector.
  6. Remove the bulb from the headlamp assembly by twisting the bulb counterclockwise.

  • Replace a high beam bulb with another high beam bulb. The high beam bulb has a red gasket.
  • Replace a low beam bulb with another low beam bulb. The low beam bulb has a gray tip and a yellow gasket at the base.
  1. Install the new bulb to the headlamp assembly by twisting the bulb clockwise in order to lock in place.
  2. Connect the electrical connector to the bulb.
  3. Install the headlamp assembly.
  4. Install the headlamp retainer pins.
  5. Rotate and lock the pins in place.

you may have a bad or broken sway bar link, or the bushings. if the sway bar links break it will sway wildly especially on corners. on some vehicles they are hooked to " A " frame which is hooked to tire, this is why the tires go crazy. have a great day !!

Not getting a good signal from all the wheels, or something is out of synchronization.

Could be a front bearing going out.. I'd pull the ABS sensors out and see if they have any metal build up on them (Bad bearing)

hope that helps

The ABS light is triggered (usually) when one or more of the wheel mounted sensors fails. Especially the front ones. They are magnetic, and pick up the metal shavings from the rotors. Once they get sufficiently fouled, they kick on the ABS light. Usually cleaning them and resetting the computer will shut off the light. In rare cases you'll have to replace one or all of the wheel sensors.

the fuel pump relay is located in the underhood fuse box. but it is not required to replace if it is defective then was probably the problem all along

Yes you will have to lower the tank to gain access to it. it is on top of tank

drop the gas tank and the inlet to your tank turns. you may need to tap it with a hammer to get it to turn. your fuel pump is in there. make sure you unhook the battery before you start.

Most likely, this situation is caused from Rust buildup between the front hub bearings and spindle. GM had a bulletin out for this. It involved removing the front hubs and cleaning the surface of the spindle.

Turn on the ignition with engine OFF.
Try to start engine, then release the key to ON
Wait 10 or more minutes till SECURITY TELLTALE turns OFF.
Turn OFF the ignition, wait 5 seconds.
Repeat this procedure 3 more times, it takes 30 minutes.
You must turn the ignition key OFF before starting the engine.
To be on the safe side OFF means take the key off, and hold on your hand for 5 seconds.
If you missed something visit GM dealer, and they gladly will provide you a print out of this procedure.

get a tube of "grip fix" or "silicon sealent" (instant gasket) or the like and stick it back in holding it there with duck take till the grip fix or silicon sets,,,after that you will need a crowbar to get it out?????
trust me,,,its not going to move,,,,,if you need to remove it,,you will need to "dig it out!"

2002 Chevrolet... | Answered on Aug 08, 2010 | 57 views

I'm not sure, but I believe they just pull straight off. Try wiggling back and forth as your pull it off. But, you do need to pull it hard to get it to come off, it will not just slide off.

    • Inlet hose from the radiator
    • Radiator outlet hose from the radiator
    • Lower fan shroud
    • Surge tank hose
    • Vent inlet hose from the radiator
    • Surge tank hose
    • Engine oil cooler lines from the radiator
    • Transmission oil cooler lines from the radiator Remove the radiator chevy_sub25_02-04_rad_rem.gif

    • Radiator bolts
    • Radiator from the vehicle

This appears to be a common problem especially on the 2002 year model. There is either a bad solder connection on the display in the cluster or a defect in the resistors. The cluster is really simple to remove. See: http://tinyurl.com/2dupvmn - next, do a Internet search for a repair center in your area. See: www.instrumentclusters.com

Good luck!
