'93 100CSQ CC questions -

[Lawrence C Leung]

Hello List,

Asking for a friend.

Subj: 	'93 100CSQA 101k miles
	Climate Control system

Symptoms:	System blows full heat when temp setting is 63 degrees F or
above
		System blows full cool (okay outdoor air) when set to low

		Fan speed does NOT matter

Asking:		How does one pull codes on this CC head?
		What could it be?

			Signal failure to temp control valve (i.e. broken wire) ?
			Controller failure?
			CC head failure?

My friend and I are under the impression that this CC head is different
from the head in my '89 200Q. Are we right?

TIA?
