Have to remove the seat & replace the blower


The dealers usually have seat people that come in
one day a week after the service bays close,like 5:30
to 8:30 at night


Could be a seat control module or other
neat little semi conductors hidding in the back of the seat


Need pro scan software to get enhanced codes

A repair shop may do seat work,would be cheaper

In the USA the right side of the vehicle is the passenger side and the left is the driver side.

SOURCE: 2004 toyota sienna a/c not working one side cold other side warm

there are two a/c lines that run down the fire wall under the van to the rear.right around the bottom of the fire wall the is a connection point on both lines. you will find a leak there .replace the orings and recharge system. also you will need two specail toyota tools to release the couplings.i have done this repair on several sienna's. let me know if this helps.

SOURCE: A/C is blowing much colder on passenger side

If it has dual climate control, the switch could be going bad. As for hardly cooling the compressor noise could be it going bad and maybe losing pressure. Some A/C shops will hook it up for free and at least tell you what they think may be wrong.

SOURCE: A/C on driver side of my toyota does not cool

well if the passenger side is getting air and its cold then you know the A/C is working..look under the dash and see if the plastic piping came apart to where it goes to your side of the vents...sometimes they slip off....and you can be blowing the cold air inside your dash somewhere....i doubt this but its not uncommon..but you can also have a blockage in your driver side vents...

2007 Buick Lucerne CXL: Cooled seats not working. LIghts come on, temperature adjusters work but the motors under the seats do not come on.


Air Circulation
When the heated/cool seat switch is pressed to initiate operation of the climate control seat (CCS) system, cabin air is drawn through the heated/cool ventilation module air filter, then directed through passages in the foam of the seat cushion and seat back to the seat's occupant. In order for the CCS system to operate to its optimum performance, it is crucial to have unrestricted air flow through the system. A dirty or restricted air filter, the blockage of an exhaust air duct, a misaligned heated/cool ventilation module, or incorrect foam installation of the seat cushion or seat back will all have negative effects on CCS operation.
Heated/Cool Ventilation Module
Each heated/cool seat has 2 ventilation modules, one located under the seat cushion and one located in the seat back. These modules are controlled by the climate control seat module (CCSM). Each ventilation module contains a thermo-electric device (TED), a temperature sensor, and a blower motor. The TED and temperature sensor are mounted downstream of the blower motor. Each TED consists of a circuit of positive and negative connections sandwiched between 2 ceramic plates. Each ceramic plate is equipped with copper fins for heat exchange. The air flowing past these fins is either directed as conditioned air into the seat cushion and seat back, or directed into the cabin as waste air.
A TED is essentially a solid state heat pump that is used to heat or cool the air supply to the seat cushion and seat back. When voltage is applied to a TED, one side releases energy as heat, while the opposite side absorbs energy and gets cold. When the polarity of the current flow to the TEDs is switched, the hot and cool sides of the TED reverse.
During the following climate control seat system description and operation, the TEDs, blower motors, and temperature sensors will be referenced independently even though they are all packaged together as a module.
Climate Control Seat (CCS) System
The CCS system consists of two heated/cool ventilation modules and one climate control seat module (CCSM) that controls both the driver and passenger heated/cool seats systems. The CCSM is mounted below the front passenger seat cushion. It receives power from both, battery positive voltage and ignition 3 voltage.
Once a CCS system is activated, cabin air is drawn through the seat blower motors and directed across the fins of each of the thermo-electric device (TED) located under the seat cushion and in the seat back. The air is either heated or cooled as it passes over the TEDs. This conditioned air is then directed through channels in the foam of the seat pad and through small holes in the seat cover to the occupant. Once the system is activated, the CCSM uses a set of algorithms to control the temperature of the selected heating or cooling modes.
Your best bet is to take your vehicle to a qualified repair shop an have it diagnosed .

Got a1997 cadillac deville got heat on passengers side no heat on drivers side could you tell me the problem.no defrost on drivers side either help please


DTC B1340 Air Mix Door #1 Movement Problem !
The heater and A/C programmer supplies voltage to an internal motor that drives the air mix door. The heater and A/C programmer monitors the air mix door position feedback from a sensor on the motor. If the air mix door is requested to move but the feedback voltage does not change, the heater and A/C programmer will store DTC B1340. If the air mix door feedback indicates that the feedback is near the hot or the cold extreme, the DTC will not set. Evaluate the operation of the air mix door through self diagnostics as described in the test description.
Test Description
Perform the Diagnostic System Check before continuing with the diagnosis of this DTC.
A Scan Tool allows for the direct control of the air mix door by observing the following conditions:
• The air mix door position feedback value
• The value`s difference from the air mix door commanded position value
These readings indicate a fault internal to the heater and A/C programmer in the air mix door sensor feedback.

Did you perform the Diagnostic System Check?
--
Go to Step 2
Go to Diagnostic System Check
2
With the engine running, connect a Scan Tool .
Turn the dual zone to OFF (passenger temperature offset at 0 or OFF).
Exercise the suspect actuator using the temperature control on the control assembly.
Is the door being commanded (COM) to the proper high and low values?
COM High 100 %
COM Low 0 %
Go to Step 3
Go to Step 4

If you are unfamilier with this , i suggest you take it to a ASE certified repair shop or the dealer .

Heater not blowing hot air


when you operates the heater button worm water of your engine's water jackets enter to the evaporator locates inside your A/C blower & air flows through it & air becoming worm. Therefore I proposed you to check your vent linkages for vent doors inside the blower unit.

Automobile air conditioning on max cool, blows hot air on passenger side tried dual climate control settings still cold on driver hot on passenger


I had the same problem when i was working on my 1999 Buick Regal and had to disconnect the battery. I didn't reconnect in the same way that I disconnected the battery from the terminal and noticed that the driver side had no heat or air but the passenger side did. I then disconnected the battery again and reconnected it the same way and now have heat and air on both the driver and passenger side. Hope this helps. Good Luck!

Sounds like a problem with the "Drivers side temp actuator motor".
Each side has a motor that controlls the temp. door inside the dash for the driver or passenger side. These motors are approx. $75, plus 1 hr. labor to install. See more info here...
