How to remove a steering column off a 2004 gmc hd

First thing is to get safety glasses,block wheels securely !!...set emergency brake..,get a good flashlight.Disconnect negative battery cable...Some can wear inside the steering column,some can be a worn linkage cable ...The lever on the transmission located under vehicle Trans at lower part of trans,driver side can become loose or possibly damaged...First get under vehicle with safety glasses and observe operation of the lever where shift cable is mounted while assistant puts it in park...make sure the trans shift lever mounting nut is tight before shifting..If assistant can't get it in park use your hand and push forward on the linkage arm and it should go into park manually...If this is the problem you need to change shift cable...Some wear inside the column where steering wheel is mounted..If cab shifter feels very loose ..You will have to remove steering wheel and column cover to inspect."..The cable runs from trans to the steering column..Look between gas and brake pedal and verify cable coming up through floor board and runs to steering column...Double check shifter lever at trans is tight because it is mounted on a splined stud and it can strip the stud threads if it becomes loose..If loose remove lever and inspect splines for damage..Call dealer and make sure they have the part..Remove old cable from trans and put it in park with your hand...Remove and replace cable..Be sure lever inside cab and lever on the trans are both fully engaged into park while cable is removed before installing new cable....Attach new cable.....

The ignition key must be in the key cylinder for cylinder removal. The key cylinder must be removed first before removing ignition switch.REMOVAL 1. Disconnect negative battery cable at battery. 2. If equipped with an automatic transmission, place shifter in PARK position. 3. Rotate key to ON position.4. A release tang is located on bottom of key cylinder.5. Position a small screwdriver or pin punch into tang access hole on bottom of steering column lower cover.INSTALLATION 1. If equipped with an automatic transmission, place shifter in PARK position. 2. Position key cylinder into steering column as it would normally be in the ON position. 3. Press key cylinder into column until it snaps into position. 4. Check mechanical operation of switch. Automatic Transmission: Be sure transmission lever is locked in PARK position after key removal. If key is difficult to rotate or is difficult to remove, the shift lever-to-steering column cable may be out of adjustment or defective. If key can be removed, release lever mechanism may be defective. Release lever mechanism is not serviced separately. If repair is necessary, the steering column must be replaced. 5. Connect negative cable to battery. 6. Check electrical operation of switch.

The wires are probably broken. They follow the shifter down into the steering column. After many years of shifting the wires break. You can find the wires inside the rubber piece that surrounds the gear shifter. They're orange. You can splice them and put them back in.

This Is Park Lock Cable Failure here is the Replacment Procedure

FOR THE DIY IT IS A RELATIVELY EASY TASK. THE STEERING COLUMN COVERS WILL NEED TO BE REMOVED FOR ACCESS TO SWITCH. THESE SCREWS ARE LOCATED IN BOTTOM OF LOWER COVER. HOPE THIS HELPS!!

no, u shouldn't have to pull the steering wheel. pull the cover off the column, there are 2 or 4 nuts that hold the column up to the dash, remove them and let the column lay on the seat- u should disconnect your battery before doing so. you can get to the shift tube from there- most likely u'll find that the bushings have gone bad and need replacement.

center console shifter? if so, likely could be a misadj shift cable, you can pull loose top cover per instruction maneul tells you how to get out of park till you can get it adj, or repaired

>>>>FIRST disable the air bag system
You'll need to remove the upper and lower steering column covers.
Also all the trim under the drivers side, kneee bolster, etc...
The ignition switch has 2 screws holding it on.
Remove those screws and all related wiring harness.
Then the switch.
Here is the procedure from GM......

Place the multifunction lever in the center or the OFF position.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Disconnect the battery negative cable.
Disable the SIR system.
Remove the steering wheel inflator module.
Remove the horn plunger contact.
Remove the steering wheel.
Remove the tilt wheel lever.
Remove the ignition lock cylinder. Remove the upper steering column trim cover.
Couldnt find a diagram. Hope this helps.

Pull hard on the steering wheel to the left and the steering wheel lock mechanism should release. I mean pull hard to left because shift interlock is froze if you cannot get it this way you will need a pro to help! Good Luck Mate.

1. Disconnect the negative battery cable.

If necessary for access or service remove the steering wheel. Except for on 1967-69 simulated wood wheels, be sure to use a steering wheel puller.

1. Remove the nut/bolt from the upper intermediate shaft coupling, then separate the coupling from the lower end of the steering column.
2. If equipped with a column mounted shifter, disconnect the transmission control linkage from the column shift tube levers.
3. If equipped with a floor shifter, disconnect the backdrive linkage.
4. Disengage all of the electrical connectors from the steering column assembly.
5. Remove the floor pan cover-to-floor screws, the floor seal, and the cover.
6. Remove the steering column bracket-to-instrument panel nuts and carefully lower the column. If equipped with an automatic transmission, disconnect the shift position indictor pointer.

Once the steering column has been removed from the vehicle, be careful not to drop it (especially on it's end), lean on it or damage it in any way; the column is very susceptible to damage.

1. Remove the column from the vehicle.

To install:

1. Position the steering column in the vehicle. If equipped with an automatic transmission, connect the shift position indicator pointer.
2. Raise the column into position, then install the column bracket-to-instrument panel nuts and tighten to 25 ft. lbs. (34 Nm).
3. Install the floor pan seal and cover, then secure using the retaining screws.
4. Engage all of the electrical connectors to the steering column assembly.
5. If equipped with a floor shifter, connect the backdrive linkage.
6. If equipped with a column mounted shifter, connect the transmission control linkage to the column shift tube levers.
7. Connect the intermediate shaft coupling to the lower end of the steering column, then secure using the nut/bolt.
8. If removed for access or service, align the matchmarks and install the steering wheel.
9. Connect the negative battery cable.

Good luck..
