*BEFORE REMOVING ANY COMPONENTS DISCHARGE THE A/C SYSTEM*

 

Start by removing the lower dash panel and glove-box assembly retainer screws from the cross bar.

Then remove the passenger side inner kick panel for better access.

After loosening the crossbar nuts on both sides and positioning it up for clearance, remove the clips securing the evaporator box halves together as well as the metal straps holding the evaporator unit to both the heater core box and blower motor housing.

Now seperate the two box halves. You'll have to be a little persuasive since they've been in there for 20+ years.

After removing the bottom section, pull out the evaporator assembly. It may be easier to go ahead and unbolt the upper box section from the firewall for better access. *NOTICE* there are electrical connectors screwed into the upper box. Unscrew and remove the retaining tabs holding the connectors in place.

Notice the vacuum lines and solenoids pictured. Make a note where they go for re-assembly. NOTE this is a good time to remove the evaporator drain hose going to the floorboard under the carpet.

Here are the electrical components you will need to re-install:

Now is a good time to install the firewall plug.

NOTE the hole next to the plug would be perfect for a wideband a/f meter or something similar.

 

Now install the a/c delete duct

After the delete duct is installed, position the solenoids and electrical switches out of the way for the glove box assembly using zipties or equivalent.

Now re-install the glovebox and lower panel. Clean up debris and your ready to roll! :)
