SOURCE: 2000 Chrysler Cirrus: I was just informed by my

I'm reading the instructions at autozone.com, and I don't see anything about removing the dash. You do have to pull out the trim around the control unit and unscrew the unit to get to the back of it, but I don't see why you can't get to all the cables and doors by sticking your head under the dash. If I were you, I would do it myself. This would be about a 1 hr job for me. Maybe a little longer if I was new at it...let me know if you want me to copy the instructions and send them on.

Heater core in my 1999 Dodge Durango needs to be replaced and I am seeking information on how to do that.


Inspect/Replace If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.
