You are going to have to have an a/c recovery machine to evacuate, vacuum and recharge the a/c syst\em. You have to remove the whole instrument panel and lay across the seats, and then remove the heater box. You will disassemble the bos to get to the evaporator. Reassemble, vacuum the system and recharge it. If you want to do it yourself and don't have access to an a/c machine you could go to a shop or dealer and have them evacuate it and recharge it after you are done with the repair. I enclosed the instructions. This is a very big job for alot of do-it-yourselfers. It would be best if you bought a manual for it before you started. Good luck, and if you run into any problems or need anything else let me know.

 

 

  1. Disconnect and isolate the battery negative cable.
  2. Remove the trim from the right and left front door sills. .
  3. Remove the trim from the left and right cowl side inner panels.
  4. Remove the steering column opening cover from the instrument panel. .
  5. Remove the two screws that secure the inside hood latch release handle to the instrument panel lower reinforcement and lower the release handle to the floor.
  6. Disconnect the driver side airbag module wire harness connector from the instrument panel wire harness at the instrument panel lower reinforcement.
  7. If the vehicle is so equipped, disconnect the overdrive lockout switch wire harness connector from the instrument panel wire harness near the instrument panel lower reinforcement.
  8. Remove the steering column from the vehicle, but do not remove the driver side airbag module, the steering wheel, or the switches from the steering column. Be certain that the steering wheel is locked and secured from rotation to prevent the loss of clockspring centering.
  9. From under the driver side of the instrument panel, perform the following:
    1. Remove the screw from the center of the headlamp and dash to instrument panel bulkhead wire harness connector and disconnect the connector.
    2. Disconnect the two body wire harness connectors from the two instrument panel wire harness connectors that are secured to the outboard side of the instrument panel bulkhead connector.
    3. Disconnect the three wire harness connectors (one from the body wire harness, and two from the headlamp and dash wire harness) from the three junction block connector receptacles located closest to the dash panel.
    4. Unsnap the plastic retainer clip that secures the park brake release linkage rod to the lever on the back side of the park brake release handle and disengage the linkage rod end from the lever on the handle.

  18. Roll down the instrument panel and install a temporary hook in the center hole on top of the instrument panel. Secure the other end of the hook to the center hole in the top of the dash panel.

  20. With the aid of an assistant, remove the temporary hook and lift the instrument panel assembly off of the roll-down bracket screws and remove it from the vehicle or lay it across the seats.

Recover the refrigerant from the refrigerant system. Remove the front expansion valve from the evaporator tube mounting flange. Disconnect the heater hoses from the heater core tubes. Remove the four nuts from the heater-A/C housing mounting studs on the engine compartment side of the dash panel Disengage the front floor panel transmission tunnel duct from the adapter on the heater-A/C housing. Remove the nut that secures the heater-A/C housing mounting brace to the stud on the passenger compartment side of the dash panel. Pull the heater-A/C housing rearward far enough for the mounting studs and the evaporator condensate drain tube to clear the dash panel holes. Remove the heater-A/C housing from the vehicle.

Disassemble the heater box and replace evaporator.
