Put another steering column in 98 gmc 1500 will

Been to long since I worked on a 98. Best guess is the turn signal switch. It could be the clock spring at the steering wheel. Both are a steering column issue.

only if you bring the chipped key for the replacement column and ECM as well
otherwise it would be like trying to start another car with your key

The shift column should not be moving only the shift lever and the linkage or cable attached to the shift lever. Tighten up the shift column mounts to hold it good and secure

the split ring in steering column is a ground to horn relay if wire touch ground or pad is compress horn will be active
hope it helps

you need to replace the ignition switch in the steering column.
broken = won't release the steering wheel lock and will not engage the start position.

disconnect battery for 25sec.

Hi.

Below you get all the parts breakdown for GMC Sierra 1500, including steering column assembly:

Here diagrams for all 1989 GMC trucks.

If you need to take apart the steering column you will also need wiring. below the color codes and wiring tips:

If that is a column shift most likely the cable has broken or you have a transmission linkage problem. I usually see this problem with a console shift unit and the solution is to turn the collar on the steering column by hand to get it in gear properly. You have to count the positions. look under the dash for a cable that connects to the shift arm and leads to the firewall or floor of the vehicle. If there are no cables check the area where the steering column goes through the firewall on the engine side and check to make sure that all the linkage is properly connected.

if there was a chip in the key you will have to get the new colum programed to match the orginal computer

Either the horn itself is bad or the horn switch is bad in the steering column. Try running a hot wire straight to the horn to c if it works
