In all the Windstar models, basically removing just the lower heat ducts will provide clear access to the heater core.

See "Related Links" below for the Autozone.com online illustrated repair guide for replacing the heater core(s) on 1999-2003 Windstars

NOTE: Autozone now requires free registration to access the repair guides. More than worth the extra effort for these photo/illustrated instructions.

Note: the procedures are essentially the same for all model years of the Windstar mini-van.

NOTE #2: for a sense of pricing, Autozone has the front for around $55

Autozone has an on-line detailed & illustrated repair guide, including the heater core replacement procedures.

The good news for the Windstar is the entire dashboard does NOT have to be removed in order to replace this heater core! Seems most vehicles for many years make this a huge project - but the Windstar looks to be much less involved.

Sounds like you heater core I would not try to fix it yourself as it could be a big job, take it to your local rad shop would be the best.

At the bottom of the center of the dashboard.

It is relatively easy to get to and repair/replace - simply remove the lower ductwork and trim pieces.

Heater Core

Inspect | Replace

Drain the cooling system

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 is therefore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

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 access 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.
