You have an '86 TQ correct?  I believe you have the older style climate
control.  This is not the digital type that will give you diagnostic codes,
this style you have to figure out yourself.  The way to be sure if it's the
older style or not is to check & see if the switch for the rear window
defroster is part of the digital face, or if you have a separate switch in the
dash for the defroster.  The digital type will hve a separate switch.

Also, I think the way to enter the diagnostic business is to press the outside
temp button & "Off" at the same time.  I think.  Maybe.  Can't remember.  Hope
this helps...
