SOURCE: 1993 Ford Aerostar - Replacing heater core

Inside on the passenger side under the dash you will find a large black box. It has several screws holding the cover on. You remove the core from there. It helps to take the jockey box out first. But, the hoses to the core are outside under the hood on the passenger side. These usually have C-hook clamps on them. That means you need a special tool to get the clamps off, then the hoses slide off the rubber gromet on the core from the outside, by simply pulling on them. You can find the two hoses on the far left when you are outside on the front of the vehicle. They project from a small are on the side of the heater fan housing. Remember to save the clamps, most new cores do not come with.

I have a 1992 olds 98 regency need a evaporator core to be taken out and install a new one.How can I get the schematic diagram to do the job. ...

in my experience finding specific directions on how to do that are nearly impossible to find due to the strict EPA regulations on the use of refrigerant. but when i replaced the evaporator core on my tahoe i found it helpful to go on to youtube and search how to remove the dash. once the dash is out disconect the lines going to the evaporator core and the heater core from the engine side of the firewall. from inside the vehicle remove all screws securing the heater box to the firewall. you have to search for one or two hidden screws. looking from the engine side may make them visible. the heater box should pull out easily if not you missed a screw. once out of the vechicle remove all screws hold the box halves together, mine had about fifteen going all the way around it. open it up remove the evaporator core, clean any dirt, leaves etc. out of the box. replace core and reinstall. honestly not a very difficult job, but it is time consuming. hope this helps.
