It is a major undertaking to replace the front heater core, or the AC evaperator. They are both housed inside a plastic chamber behind the dash. You have to remove the left side of the dash, and all associated wiring, lower the steering column, and open the AC system in order to get the Heater/AC chamber our to remove the top of the chamber and lift out the heater core. The Haynes manual gives a step-by-step directions. It took me most of the day to replace my AC evaporator. Good luck, and don't forget to connect back up all the electrical plugs.
A "heater" or a "heater core"?
remove steering column, pull back dash to passenger front seat, you do not have to dis-assemble entire dash panel. You can access plenum (heater box)this way.
To replace a 1988 Dakota heater core, first discharge the A/C. Then remove the lower instrument panel before removing the heater box unit.
The dash has to be removed to gain access to the heater box. The heater box then comes out and is split open to replace the core.
no, you do not need a compression tool to remove or replace them
replace the heater core if that's not it start checking fuse
