Usually this is from a burned up blower motor resistor. Not very expensive to replace, but can be a pain to get to. I do not think it is that bad on the 05 Buick though. It should be in the bottom of the AC/ Heater box under the passenger side of the dash, like under the glove box area. pull the lower trim panel under the passenger side of the dash and there should be a wire connector going right into the bottom of the heater box. unplug the wire and there should be 2, 7mm if I am not mistaken, screws holding the resistor block into the heater box.

SOURCE: blower not working on ac or heater etc.

A very common solution here is replacement of the blower motor resistor. The resistor when they break do one of two things.

A. work only on high

B. dont work.

This item is located on passanger side under dash and is usually held in with two small bolts on either side with an electrical connector seperating the mounting screws. It is mounted right in the air box. I replace at least one of these a week in my shop very common item.

SOURCE: 1996 buick riviera blower motor will not shut off

The blower motor control module needs to be replaced, that will solve the problem. The module is underneath the hood on the firewall in the back. It has 2- 6mm screws. Unplug it, pull it out, put the other one back in. Plug it in. This is common for this model buick.

SOURCE: Replaced bad AC unit with floater pully, now no heat, overheating

most likely when you replaced coolant line and refilled rad the system was not bled properly.
fill the system with 50/50 again and top up the reservoir. run the engine to 2000 rpm and look at temp gauge . it should rise to middle and drop to low this means t stat opend and air is out now let engine idle and top up coolant. good luck

SOURCE: 1996 Regal: No heat, Radiator Fans wont work, Over heating.

If the thermostat is not opening then the engine heats up. So I would replace that first and then see about the fans not turning.

Hope this helps

The A/C will not turn off on my 2006 Kia Sedona EX. Air blows cold, but no matter where you set the control knobs for A/C system or fan controls the A/C stays on. Even with knob in the OFF position.


Looking under the hood in engine compartment with engine running A/C off , the compressor is engaged ? If so , the A/C compressor clutch relay is stuck closed energizing the compressor clutch all the time . Now if your talking about the blower inside the car running all the time , air blowing out of the vents . The A/C isn't engaged . Could be blower motor relay stuck or the control module is bad .

Engine and AC fans start spinning


If that is the same thing as Defrost, the compressor will run even if the ac button is off. The compressor runs to dry the air blowing on the windshield.

The compressor wont turn off when I turn it off thru the controls inside the car. blower fan turns off compressor remains on. Please HELP!!


motor has load on it that is why it idles low, my 07 does the same when I put ac on, as to why it does not turn off when you turn control off, under hood, is fuse # 9 40 amp fuse, pull it and see if it stops and idle recovers, could be a shorted wire that controls it

I turned on the ac and the light does not work, the vents are not blowing and the car is running hot. I have a saturn SL 1996


First check the 15 amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under a cover. If the fuse is good, then the problem may either be the HVAC blower switch (which is the fan blower selector switch), the fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components.

Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well (working) because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on. What the ac light switch does is provide the electrical path for the ac compressor clutch to come on through the ac control relay which is controlled by the car's PCM(computer) when you want ac, but the ac light switch still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path(negative) from the blower motor. So the blower motor has to work in order to provide a ground path for the fan blower selector switch to be functional. You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. You'll see it. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. Unclip the connector and with the ignition on and the fan blower switch moved to any one of the first 3 selections, check for voltage using a multimeter. The voltage will vary because there is a blower motor resistor. Voltage should be higher on setting 3 than 1. If you do have voltage at the blower motor connector, check for a faulty blower motor. The auto repair manual will tell you how to do it using jumper wires.

It's normal that your car is running hot because the radiator fan works in conjunction with your ac compressor. If the ac is on, the radiator fan will be on and therefore the engine coolant temperature will stay in it's normal operating range. If the ac is off, the radiator fan will stay off as well and the engine coolant temperature gauge will begin to rise and show pretty hot (especially at idle). It will do this up until a certain degree then the radiator fan should turn on thermostatically and stabilize the temperature. It's scary and I know what your saying because it does that to my car if my ac isn't on. Don't worry it won't overheat.

Heater Fan does not work


Sounds like the fan control knob has shorted out. You can check the fan "blower" relay and fuse in the engine compartment but you need to make sure the control knob is good or you will keep blowing fuses and relays. If your blower fuse and relay are good, then just have the control knob checked and replaced if needed.
