AC blower motor wheel project
 

I have been thinking about doing this for awhile. I wanted to see if could get the AC to blow hard like a late model. After some research I found a late model blower wheel that was the right size. I had to buy blower motor with the wheel just to get the wheel. I got it on ebay for $33.00 it is for a 07-11 jeep liberty. The wheel has 41 fins on it and my 72 AC wheel has 29 fins. The fins on the newer one are also much larger. This took me a few hours to put together. The new wheel would require a much longer shaft that my motor has so I cut the center out and I clipped and cleaned up an old chevy blower wheel and epoxied and rivet them together. The fit was so good they self centered themselves. I had to open up the blower housing hole about a 32d all the way around to get the wheel in. Also took some side cutters and clipped the top of the fins at an angle for clearance. This runs smooth and quiet and blows hard. I think on medium it blows about what it used to on high.

Now that is a good project. Thanks for that info and pictures.

P.S. what is the difference in the heater only wheel, this may help us non-AC guys too.

Re: AC blower motor wheel project
 

Thanks! I'm sure that will be one of my future mods.

Bill, I do not know about the heater only wheel. I am sure someone here does.

A short video trying to show how it blows out the center vent. https://youtu.be/hcRlWh4QmM8

Re: AC blower motor wheel project
 

It's saying the video is unavailable when I try. However your mod is on my list of things to do.

Re: AC blower motor wheel project
 

Ok I will try to work on the video. Thanks

Re: AC blower motor wheel project
 

It's not just a Red71gmc problem....I couldn't see the video either. Looks like a very good mod, thanks for posting!

I looked through your driver build rsgt. Your a resourceful guy. My truck originally was the same colors and I wish the PO would have repainted it those colors. It just looks good on these trucks. Especially with the rally rims. Good job.

Your video worked this time. I will be doing this. It looks like it could be used for a hair dryer if I just still had hair.

Re: AC blower motor wheel project
 

That looks like it's pretty strong. I wonder if it would work on a 64 SS Impala as well.

rsgt,
Here is your link. :chevy:

Andy, It might work, The wheel is 2 3/4 inches by 5 3/4 inches.

Re: AC blower motor wheel project
 

Here are a couple more pictures. I put a heavy weight on the wheel when I glued them together, Then when it was cured I put the rivets in. I put a weather strip seal around the edge of the motor plate before I put it back on the truck.

Re: AC blower motor wheel project
 

Andy, What you have to watch for is depending on the car, The wheels come in clockwise and counterclockwise.

Re: AC blower motor wheel project
 

Thanks, the truck does pretty good as is but my 64 SS on high is like slow speed in my 71 C 10.:chevy:

Re: AC blower motor wheel project
 

Tagging so I can find it later. Nice mod!

Re: AC blower motor wheel project
 

I did your mod on mine when it put it together a year and a half ago. It works great.

Re: AC blower motor wheel project
 

Where do you guys find the time to do this? On my list now twice!

Can't speak for trucks but the hot tip for C3 (68-82) Corvette blower motors was to use C4 (84-96) Corvette blower motors and add a 3/4" spacer. Not sure if they had more blades but they were at a different pitch and the cage was longer. It supposedly worked well although I never did one.

Also, posting just so I can find it later.
