Hi! I got problem which driving me crazy after fixing my ac compressor in one of toyota services. I have Toyota Rav4 2011 Limited 2GR-FE V6 and my problem is that when i put air condition on LO its ok there is no heat blowing out. But if i put just TEMP+ to just 65 degrees only (just first higher one avaiable after LO) it starting to blow ultra lava heat on my face. I checked on OBD2 Port whats going with Torque aplication and it showing me : passenger+driver inlet temperature set : 95F while on 65F in control panel in car. I was like omg thats too high and when i go Temp+ values they going consistenly 1F but 30F difference. so if i set 65F it shows in OBD 95F if i set 75F in car, it shows me 105F in obd. I remember i was checking these parameters 2 years ago and they were FINE and now i have 30F difference. It is possible to make correction with techstream or something? Like connecting to A/C ecu and just reset this? Please answer, its making me cry lol! They just broken it up in toyota service and they wont fix it since "They dont know how to, we are proposing you to buy new console for milion dollars and it will fix all your problems" Please answer someone. :(

Run this diagnostic procedure and see if any error codes show up:


CHECK MODE PROCEDURE
1. PANEL DIAGNOSIS (INDICATOR CHECK)
(a) Turn the ignition switch to LOCK.
(b) Turn the ignition switch ON while simultaneously
pressing the A/C control AUTO switch and the REC/
FRS switch.
(c) Check that all indicators and the display area are
turned on and off 4 times in succession at 1 second
intervals.

HINT:
After the indicator check is completed, the system
automatically enters sensor check mode.
(d) Press the OFF switch to terminate the panel
diagnosis.
2. PANEL DIAGNOSIS (SENSOR CHECK)
(a) Perform the indicator check.
HINT:
After the indicator check is completed, the system
automatically enters sensor check mode.
(b) Press the REC/FRS switch to enter actuator check
mode.
(c) After the actuator check is completed, press the
AUTO switch to enter sensor check mode.
NOTICE:
The sensor check must be performed again after
the actuator check is completed because sensor
check mode, which starts automatically after the
indicator check, cannot fully detect
malfunctions.
(d) Check the sensor check results displayed on the set
temperature display.

HINT:
• The illustration shows the display when code 21
is output.
• When 2 or more sensor check codes are
detected, the codes are displayed in ascending
numerical order.
• In cases with 2 or more codes, if they are difficult
to read, press the DEF switch to activate the step
operation and display them one by one.
• The codes are displayed in ascending numerical
order as the DEF switch is pressed.
(e) When any sensor check codes are displayed, refer
to the DTC chart (see page AC-39).
(f) Press the OFF switch to terminate the panel
diagnosis.
HINT:
Pressing the REC/FRS switch returns the system to
actuator check mode.

3. PANEL DIAGNOSIS (CLEAR SENSOR CHECK CODE)
(a) Inspect, and repair or replace the malfunctioning
parts.
(b) Clear the sensor check codes.

(1) While pressing the DEF switch during sensor
check mode, press the Rr DEF switch.
HINT:
Sensor check codes can be cleared by removing
the ECU-B2 fuse from the engine room No. 2
relay block for more than 60 seconds.
(c) Perform the sensor check and confirm that normal
code 00 is displayed.

4. PANEL DIAGNOSIS (ACTUATOR CHECK)
(a) Start the engine and warm it up.
(b) Perform the indicator check.
(c) When the sensor check is started after the indicator
check, press the REC/FRS switch to start the
actuator check.
HINT:
Perform the actuator check with the engine running.
(d) Check the temperature and blower levels by hand at
each step while the actuator check proceeds from
step 0 to 9 at 1 second intervals (continuous
operation).

HINT:
Each step number is displayed on the set
temperature display.
(e) To display step numbers one by one manually,
press the DEF switch to activate the step operation.
The step number changes each time the DEF
switch is pressed.
HINT:
• Each step number blinks at 1 second intervals
during the step operation.
• The illustration shows the display when step
number 5 is displayed.
(f) Press the OFF switch to terminate the panel
diagnosis.
HINT:
Pressing the AUTO switch returns to sensor check
mode. __
