Open the hatch, remove the panel to your left. You'll find the blower in there.

Contact the dealer for the location of the blower motor and then roll up your sleeves and get to work!

Before you take out the motor you might want to verify that it is receiving power. If not receiving power the motor could be good and the problem could be with the wiring - no need to replace a motor that is still good!!!!!!

Lincoln MKX.....duel climate control......heat working on drivers side but not on passenger side.....blower is working....no heat just cold air.


There is a part called a air temperature control blend door in the ducting of the system and the door is operated by a tiny DC motor, if the passenger side will not change temperature at all then this little motor may be defective or the door is warped and sticking from heat.

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 .

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Rear a/c doesn't work i bought a blower motor and connect it to the car but still did not work


Check voltage to all three parts: the blower motor, the blower resistor which is directly connected between the motor and the the switch, or also it could be the switch (remember secure you ground the negative side of the voltmeter to either the battery or to the ground car).

Generally the auxiliary climate control system has dual controls for the driver and rear passengers consisting of temperature/air distribution and blower speed; the rear auxiliary climate control assembly is mounted in a separate overhead console positioned on the headliner above the second row seating area.

Also, with the Owners Manual, you can check the relays substuting it in each position in the fuse panel.

Blower fan motor not working


this fan is controlled by a fan relay, located under the dash. Most likely replacing that relay will solve your problem. Go to any autozone store, but the part and ask them to assist you in changing it. they offer this assistance as a free service.

Heat works in the rear but not in the front,the blower works but it blows cold air


damper in duct to change air flow from heat to air is not working most probably. I am almost certain the navigator will have an actuator motor that has stripped, or the motor has gone bad this is constantly working when you use climate control to control air temperature.
