No power to heat control or blower motor

2000 olds intrigue, i have no power to my air controller, and my blower motor. i've used a voltmeter to test for any electric current at the blower motor but i have nothing, i've checked the fuses and they're all good, im out of ideas, can anyone help???

Check the wiring to the starter. I have a 2000 Intrigue and the heating/AC unit would not even light up. We checked all the fuses, even tried pulling it out and checking the unit itself. Husband called dealer about replacing $1100, no way to get that, then the starter and fly wheel broke. Bought them and brother-in-law replaced them, when I got the car back the heater/AC unit work just like new, it was just loose connections.

R u sure u tested it correctly? There will be a 30 amp fuse usually associated with the blower motor however u need to look at the motor connections with a meter set to ac. These newer cars use a pwm type drive which is a pulsating dc voltage similiar to ac and should vary in amplitude as u turn ur control for speed. If u have that then ur motor is bad and has to be replaced.

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 .

Blower not working. How to test


if the blower is working when you jumper it at the motor you`ve eliminated the motor itself.if you have replaced the heater control with a new one or known good used one then the only thing is the blower motor resistor has gone bad.i`m surprised you did not check and replace this unit after jumping the blower motor.

Can not find heater control valve 2000 expedition


what year? for 2000, there are no control valves. It mixes a/c air with heater core air to blend the right temp.

SECTION 412-02: Heating and Ventilation 2000 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Heating/Defrosting The heating and defrosting system has the following features:
  • Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
  • Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
  • Controls the A/C blower motor speed.
  • Cooling or heating can be adjusted to maintain the desired temperature.
  • Uses a reheat method to provide conditioned air to the passenger compartment.
  • The blower motor draws outside air through the A/C recirculating air duct, except for MAX A/C cooling, when recirculated air is used.
  • All airflow from the blower motor passes through the A/C evaporator core.
  • The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • The temperature blending is controlled by the temperature blend door, which regulates the amount of air that flows through and around the heater core, where it is then mixed and distributed.

The heater stopped blowing on my 98 Olds Intrigue. I was able to use the controls on high until last night, then they just stopped. I am still getting heat, but it's not blowing. Any ideas what the problem...


Blower motors generally last about 120k miles(in Minnesota) They have brushes which eventually wear out. As they wear there is less tension on them against the comutator and so it requires more voltage to get them to run. Thats generally why "Hi" on the control is the only one that will make them run close to the end of thier life. This dose not rule out the control itself or the resistors. The resistors are located under the glove box behind the blower. Remove them and visually check their condition. Measure them with an ohm meter, they should all be less than 20 ohms. Remove the control and check it for overheating. Switches like to become resistive and overheat, melting the plastic frame and the plug. If all checks good replace the blower motor. You could check the motor by applying 12 volts to it and it would probably run but now that its removed its been bumped around and the brushes are making better contact. So don't be tricked. Like I said, if it has alot of miles on it (time) your better off with a new one anyway.

The heat will not work. No heat.


So you have power to the control unit and the blower motor. Did you check the blower motor resistor? That controls the blower on all speeds except for high speed. Did you check all the grounds? Don't rule out a faulty ground. Make sure the blower motor is properly grounded.

I have a 2002 Olds Intrigue that has an intermittent problem with the air conditioner/heater not working. No indicator lights show during this time and occasionly the Cruise light comes on. No real pattern...


Follow the blower wires. I believe you should find a relay. I suggest testing it as well. Make sure it is good. Also make sure fuse is good and secure. Test your control switches and check all the vacuum lines and wiring

Blower motor does not run on any setting. Fuses are good,


You mentioned fuses but did you make sure there is not a relay. If you have a voltmeter or test light, It is very simple to get to blower motor under passenger side panel should have to 7mm head screws take it of unplug motor turn it on put test light to b+ side see if it is getting power, If it is than the blower is most likely bad.

Climate Control only blowing HIGH and remote not working


for the first problem, it sound as if the blower motor resistor has gone out. this is a very simple repair and the part does not cost very much. If you can locate the blower motor, the resistor should be on the left side of the blower motor.
for your second problem, it sounds as if the remotes need to be reprogramed.
