On a 1993 GMC Jimmy, you generally
do not have to completely drop the steering column to replace the heater core. However, you'll likely need to significantly loosen or partially remove it to gain enough access. The exact amount of steering column manipulation depends on the specific approach the mechanic takes and the available space. Some methods may involve just enough movement to clear obstructions, while others might require more extensive removal.
Always consult a repair manual specific to your 1993 GMC Jimmy before starting the job. These manuals provide detailed instructions and diagrams showing the best approach to minimize the work involved. Attempting this repair without a manual significantly increases the risk of damage and unnecessary work.
