blower motor replacement

That is my first guess, the resister. Check that first. If it doesn't fix it, check for problems with relays. Here is a guide to check the blower motor and resistor with instructions in the diagrams below to help show you on your car.

Where do I start in replacing or fixing my heater fan blower?

Find the blower motor it should have a blue and black wire going into it? If so direct power from the battey to the blue wire-did the motor operate-let me know asap.

here is the blower ACDELCO from Amazon for $76.00

Is the blower motor not operating at all? Or only operating at certain fan speeds?.. Let me know and I will be of better assistance. You may want to first check the fuses/relays. Another issue may be the blower resister is faulty. If you feel it is just the blower motor itself that is faulty, below are removal/installation instructions for the component. REMOVAL: Remove the right closeout panel. Remove the blower motor wire harness connector. Cut out the blower motor using a utility knife in the narrow groove of the lower case (FIG. 1) FIGURE 1

NOTE: Cut through the case as straight as possible because the motor cup must be replaced. In order to prevent damage to the component, do not cut any deeper than necessary to remove the motor cup. Remove the blower motor. INSTALLATION: Install the motor blower seal. (FIG. 2) FIGURE 2

Install the blower motor. Install the blower motor attachment ring if reusing the blower motor. Tighten the blower motor screws, and tighten the screws to 13 lb inches (1.5 Nm). Install the blower motor wire harness connector. Install the right closeout panel. Hope this helps.. Thanks for using 2carpros.com!

The blower motor is not working on any speed, it has a low humming sound, therefore I thought it wasn't a fuse but the fan itself.

Could be binding within the housing try banging around to free it. If its humming on all speed setting its getting power to it thru the blower motor resistor. Disconnect the blower motor and power it direct-let me know

Thanks for your help... when we removed the motor cover it had a build up of ice in the bottom of the right close out panel, we thawed out everything and connected the motor blower up again and low and behold the fan blew on all speeds. To insure everything dries out and thaws I am letting the car run with the heater on for an extended time.
Thanks again second time you guys have gotten me out of a car problem.

Air Conditioning problem
2005 Chevy Malibu 6 cyl Automatic

My Blower remains on after the car is turned off. I have to disconnect the battery and reconnect when I want to drive my car again. I have been told there is a problem with the module. How much could something like this cost to fix?

if the module does need replaced than an estimate is below for that repair.

i suggest having a second repair shop look at it to ensure it does need the module replaced and not just a faulty relay or something else.

I have a 2005 Malibu Maxx LS. The fan for the heater/AC only works on number setting 3 and 4, not on 1 or 2. I replaced the entire control assembly with one from a salvage yard. It was tested and worked before I bought it. This did not fix the problem. What else could it be?

Suspect blower motor resistor.

Thank you, I will try replacing that next.

Wife said the A/C wasn't cold, so I charged it. three days later she said it was making a wierd noise. I heard the noise, so I took out blower. There was some debris and something I couldn't identify. Anyway, had blower running while out, A/C was on, no noise. Put it all back together, took for a drive, all seemed fine. Next day wife says the noise is back no air from vents. It looks like the belt needs replacing, could it be the tensioner making noise or just or the blower is going bad? Will take blower out again, probably didn't get the tube on correctly

What does the unidentified item look like? If it is plastic, it may be a door has dropped from the HVAC case. This would explain the vent issue. Please provide a little more info, and I'll be glad to help. Doc

It was white about the size of a fingernail and had a hook thing on it. Removed, reinstalled , seemed ok, fan making noise when turned on, recirc was on too, A/C was not on, was informed very little air from vent,

I will locate and send you an illustration of the HVAC controls and we will figure out where it lived - and a solution. Doc

I narrowed it down to the compressor, think the clutch is shot, sprayed it with teflon lube, it started working, for how long I don't know

how to install a ac blower motor on 2001 chevrolet malibu

Pretty much unplug it take the mounting screws out of it drop it down put the new one in mount it back up and plug it back in.

where exactly is it located

Its located under the dash behind the glove box sounds like your guessing its bad since you dont know where it is.

yea i'm new to this. I originally thought thats where it was and took down the glove box and saw this casing and wasn't sure if it held the b motor or the air bag and got scared to mess with it and thought i'd better ask

You shouldnt have to remove the glove its under the das behind the glove you just look up under the dash behind the box and there might be a close out panel to remove but not the glove box.

The heater/ac blower does not work on my 2000 malibu. Several months ago I replaced the resistor because it only work on the higher speeds. Now the blower does not work at all. Ivve checked the fuse and that is not the problem. Do i need to repalce the blower and how do I do that?

Thanks
John

Welcome, I'd check for voltage and ground at the blower motor connector, with the hvac control turned on. If that checks out, motor.

Ok a few months ago a piece of my ventilation came off and lodged itself in my Heat/AC blower motor(the fan). So I removed it but now my fan will not turn on at all. No heat and no air conditioning no matter what I set it to. I have replaced the fan itself as well as the BWD HVAC Blower Motor Resistor. And still the fan will not turn on at all. As I change the settings to blow through the various vents I can hear the motor change positions but still no fan. Any clue what I am missing? I checked the fuses as well.

So you can hear the fan spinning blowing air and ramping up in speed but no airflow out of the vents?Also do you have auto climate control or manual ac?

No the fan is not moving at all or on any speed or setting. I'm guessing I have auto climate control...

I really need to know if you have auto climate control or not?Do you dial in the temp number you want or do you blend the temp with your temp control?

Well... OK like I said before I'm guessing its auto.. But I have a knob on the left side of my panel for the fan that I can turn down for auto(it says auto) or I can turn it clockwise to turn it on the more right the faster the fan spins. Nothing happens when I turn the dial or if I put it on auto.

fan speed run only on high speed.couldn't work on any other speed.Please tell me how to repair.Can I do myself?

Chances are either the fan relay or the blower motor resister is bad. The relay is under the hood and I believe the resister is near the blower motor under the dash. You could easily replace them yourself. When you get the parts, have the parts store print out a schematic for you so you can locate them. It is really not much more of a project than unplugging one and replacing it with the new. THe resister may be tougher to get at, but the same with it.

Is there a screen in between the two knobs with a up and down button to change the temp bellow the screen?

Thanks for your reply.I will do myself.Thanks

Yes there is.

Do you have a test light to do some testing?Or better yet a multi meter?You will really need a multi meter to do some testing.You have a auto climate control by the way.

Well I have a test light and I can get a multi meter.. not sure how good it is and Im not sure what to test?

Unplug the blower motor the Turn the blower fan to the highest fan setting then see if the test light lights up bright across the two terminals at the blower motor connector.Next steps will need the multi meter.

Ok. I'll test it tomorrow and let you know. I'll see if I can borrow the multi meter as well.

Sounds good let me know what you find.
