Toyota Supports ASE Certification Page 1 of 3

AC001-03

Title:

A/C PERFORMANCE & DURABILITY

IMPROVEMENT

Models:

'02 - '03 Camry

Technical Service

BULLETIN

April 15, 2003

TSB UPDATE NOTICE:

This TSB updates EL004-03. TSB EL004-03 is now obsolete and should be
discarded.

Some 2002 - 2003 model year Camry owners may experience a condition where
the

blower volume gradually decreases after about 1-1/2 hours of driving. It has
been

determined that, in hot high humidity conditions, the A/C system evaporator
is freezing

over, blocking the airflow path. There may be some instances where this
condition may

affect the A/C compressor and clutch assembly. An in-line thermistor
resistor harness is

now available to correct this concern.

Thanks for the info. This problem has happened to my vehicle a few times
now. I will make an appointment with my local Toyota Service Dept. to have
this repair performed.

Sounds like all they're doing is adding another temperature sensor
on the evaporator core (or using a resistor to adjust the range on the
one that's there) to sense the evaporator core icing and shut off the
AC compressor for a few minutes.

You can do this yourself - if you think the system is icing up
because the airflow goes away, just turn the controls to full-on
"Heat", fan to low, and open the windows so you don't roast. Wait 5
to 10 minutes, and the radiant heat from the heater core (right next
to the AC evaporator) should melt that ice block away.

And then you know when it's really humid NOT to leave the controls
at full "Cold" setting, so it'll cycle and defrost on it's own
semi-automatically.

Building AC systems ice up the same way, someone sets the thermostat
at "Meat Locker Cold" so it never shuts off and never gets to defrost.
But office buildings don't get parked when you arrive (and the system
shut off for the night), so you can burn up fan motors (no airflow,
motor current spikes and no cooling airflow) and compressors when the
system pressures go nuts.

Car Guy,

Look into TSB EL004-03 this cover the same symptoms but it include checking and replacing the compressor clutch too in addition to installing inline thermistor in the blower cooling circuit.

Jack,

I do not see this TSB for the Toyota Camry vehicles. I see the following
though for Lexus:

EL004-03 MAY 03 Instruments - Mirror Compass Recalibration
Process

Could you please confirm and reply to ac222@hotmail.com or on here so that I
can take the proper TSB to the dealer.

Thanks

This TSB already mentions to examine the compressor for a rattle, and if so,
replace the clutch.
