Replace heater core 1999 Dodge Dakota V6

The hardest part is taking the dash out. Then you have to evacuate the AC system, and remove the box. Then you can open the box, and change the heater core. It's a pretty big job.

I can start you out with the dash. If you still need help, just let me know.

REMOVAL & INSTALLATION

NOTE Before beginning, be sure to turn the steering wheel so that the wheels are in the straight-ahead position.

  1. Disconnect and isolate the battery negative cable.

CAUTION On air bag-equipped vehicles, wait at least two minutes for the system to discharge before proceeding. Failure to take proper precautions could result in accidental deployment and possible personal injury.

  6. Disconnect the overdrive lockout switch wire harness connector, if equipped, from the instrument panel wire harness near the panel lower reinforcement.

IS it possible to gain access through the glove box. If not it looks like I can seperate the lower cowl under the steering wheel and leave the collum in place. Is this possible?
Expert:  ase_master327 replied 9 years ago.

You will have to roll the dash back, atleast, if not pull it all the way out.

You have to lower the column, too. Usually just the bracket part that holds it to the dash support will be al needed to do it like that.
