RE: Climate controls interchangeable?

["Livolsi, Stephane" <livols1@investorsgroup.com>]

Taka, I don't think you can because the late 87 and up CC heads have a
diagnostic feature built in.  My CC worked very erratically when I
bought the car.  When I took it out, I noticed that it was from a
salvage yard and was labeled as from an 87. (my car is early 86).  I got
one out of an early 86 and it works fine now.  The plug harness on the
87 was the same as the 86 though.  It could have just been a bad
controller but I don't think so.
good luck
