AC warm on passanger side

[Asim]

Guys:

My AC is luke cool (can I say that) on the driver side and downright warm on the passanger side. It works properly sometimes - nice and cold on both sides. So I have the problem of the temperature and different zones.

Oh yeah, not sure if it is related but my ac makes a ticking sound from the outside.

What gives?

Here's the TSB on the problem:

A/C - Lack of Cooling From Driver/Passenger Vents
Article No.
03-3-4


02/17/03

CLIMATE CONTROL - LACK OF COOLING FROM
DRIVER AND/OR PASSENGER SIDE VENT -
VEHICLES EQUIPPED WITH DUAL AUTOMATIC
TEMPERATURE CONTROL (DATC) ONLY


FORD:
2002 THUNDERBIRD


LINCOLN:
2000-2002 LS


Article 00-15-3 is being republished in its entirety to update the models covered and to update the Basic Causal Part number.

ISSUE

Some vehicles may exhibit a lack of A/C cooling from either the driver or passenger side vents or an extreme temperature difference between the driver and passenger side on vehicles with DATC (Dual Automatic Temperature Control): This may be caused by a faulty DCCV (Dual Coolant Control Valve), a faulty DATC control assembly, or faulty electrical circuits.

ACTION

Inspect and service as necessary, electrical circuits, DCCV and DATC control assembly. Refer to the following Service Procedure to aid in diagnosis and repair.

Clearly this would answer the imbalance, but is it also causing the sporatic cooling?

Thanks very much.

Asim,

If you have a faulty DATC, which is part of the TSB above, it could cause cooling problems on both sides. Have your dealer look at it according the TSB above.
