Adam, thanks for the reply. Could you clarify it for me? I am having trouble following it. Do I need to perform both steps or is one from the engine side and one from the dash? Also See A/C-HEATER ASSEMBLY ??
Thanks.
i could be mistaken (often am) but believe that "See A/C-HEATER ASSEMBLY" in the first paragraph refers to the procedure in the 2nd.
pardon if you already knew that.

Good Luck 2 ya,

Ahhh I bet you are right TN Timmy. Thanks.
I was surprised that it was this involved. It looked like the fiberglass heater box from the engine side had a cover and the refrigerant lines when right into the vap coil.
