No heat or air comes out and was told that the blower motor control was inoperable. Do I need to replace the entire blower motor or is the blower motor control a separate part?

If you have no heat blowing and no force of air in AC or blower mode , your blower motor (fan portion) under dash is the likely culprit. Check your fuses before diving in. As the motor wears the carbon brushes wear out.
A common symptom is that the motor starts and stops going over a bumpy road where its brush connection is intermittently bounced on and off.
If you only have alow or intermediate speed , that would be linked to the speed and motor controls.

1996 Lincoln Mark 8 AC controllers working blowers working nothing coming out of the vent


I noted your question. You said that NOTHING is coming out of the VENT. Do you mean the interior vents normally for heat and air? Does air blow out of your dash defrost vent? Does blower motor work continuously? If so, I suggest that you check fuse panel at driver's door. If you have your owner's guide, look on pages 251 and 252. 251 shows your interior fuses. 252 shows description for Fuse #9 (10A). You have numerous 10A fuses. #9 is the lowest fuse perpendicular to Fuse #10 (15A). If it is blown, you have some sort of resistance in one of 4 things RUN BY THE FUSE. I went to my mechanic and he told me that the Blower Motor Control Resistor behind the glove compartment was bad. I replaced it (125 dollars) and it was not the problem. Check the fuse. Is it blown? Replace and the system may work normally. If it continues to blow please get back to me. If the system works after replacement, please respond.

Kia blower motor


Not sure I follow your question. If the blower motor runs at high speed on all fan settings, there could be a short in the controller. The fan control and ac-heat control are separate circuits in the controller.

AC/Heat/Defrost inoperable


Chanses are its either the blend door motor quit working or the controls ( temp., selector, blower) in dash are bad, my 95 did the same thing i chg. the blend door motor thinking it was that, but it turned out to be the controls in the dash, 5 minutes work and 140.00 later it was fixed.

Heater always on


THE PROBLEM IS ALMOST CERTAINLY THE AIR TEMPERATURE CONTROL BLEND DOOR MOTOR ACTUATOR IS INOPERABLE, TO REPLACE THIS PART U MUST REMVIVE THE ENTIRE DASH ASSY. IT IS ABOUT CENTER OF THE AIR DUCTING BEHIND THE DASH.

I turn the heating/air fan on, the fan will not go


it sounds more like a temperature control module to me, that is the electronic module that controls your entire ac system, JUNKYARD PARTS

1995 chevy blazer heat, ac will not blow air


yes the heater controls are vacum however the blower motor is not. a new control panel is an option and may fix it. if it was my blazer i would first check the fuse boxes onder the hood and in the side of the dash driver side. if they are good i would go to the nearest auto parts store and buy a test light. this will aid you in making sure what the problem is before you go spending money on replacement parts. the blower motor is in one of two places. its most likely under the dash on the passenger side. there is a cover that you will have to remove directly under the glove box. once removed you should see a large red and a large black wire. these are the power and ground for the blower motor . in some gm's these wires go into a resistor. the harness plugs into the resistor and the blower motor wires come out of it. ok now that we are a little bit familiar with our suroundings the red wire i told you about is the hot wire if you ground the clamp on the test light to the door hindge. (make sure its a good ground by touching the positive batter terminal. if the test light lights its a good ground )now unplug the blower motor and touch the metal posts in the end of the plug that belong to the red wire. if it lights when the key is on and the blower control is on in all posisions you need a blower motor. if it does not then you need a blower motor resistor.

Heat and air does come from vents


check the vacuum supply to the control head switch, if it is automatic climate control u may have a defective control head, replace the entire unit.

Heat levels..


need new technician.if the blower motor works even with only one speed than the blower motor works and did not need replacement.sounds like blower motor resistor or resistor wiring,when there is a problem with the resistor or wiring you will only have one speed,this way you atleast have heat.so if your tech replaced the blower motor when it worked and did not need replacement then it sounds like he is just throwing parts at it,you have to wonder if he really checked anything.have the resistor and wiring checked and if ok then check the heater control head and wiring.
