More Cold Air!
Hey guys have any of you upgraded to a bigger blower motor or squirrel cage in order to get more air flow out of your A/C system. It seems like the air ducts just don't have much flow compared to a newer car. Do you know of any way to upgrade this with parts from a newer model or aftermarket stuff. It may be the case that the evaporator may not be able to deal with the extra flow and the air will just come out at a warmer temp. Have any of you guys toyed with this?

Re: More Cold Air!
There was a post a while back where someone upgraded to a fan from a 90s extended cab, I think. he said it was much better. You might find it if you search.
Here's another idea I saw on another board this morning... Slonaker Last edited by Slonaker; 07-28-2006 at 10:50 AM. |

That's genius! I can't believe I didn't think of that.
Some people just have too much time on their hands. |

I plan to pull the interior out of my 77 this winter to finish putting the Brown Bread in it. When I do I'm going to see what it takes to get better airflow from the A/C system. I'll add this mod to the list....

. Probably not worth a trip to a wrecking yard for the price of a new one. BTW: anybody have the part number handy for the variable orifices of rour trucks A/C I want to try that next.

Re: More Cold Air!
I like this part from Autozone- INCLUDES BLOWER WHEEL ALL OF AUTOZONE`S BLOWER MOTORS ARE NEW, NOT REBUILT, WITH A LIMITED LIFETIME WARRANTY.
That looks very familiar. I'll bet that part number would cross reference with quit a few mid 90's GM cars/trucks. I am curious as why it blows more. Is the motor designed to run at a faster RPM than the earlier motors? Anyone know the RPM of the 73-87 blower motor?

Re: More Cold Air!
Strictly a guess on my part, but I think the rpm's are the same and there are more fins(or a different pitch) on the cage.

Re: More Cold Air!
One thing that the poster also did was reinstall new foam to seal the all the vents and connections better. I'm not sure what its called, its foam on one side and sticky tape on the other. Most I have seen that are original turn to dust if you mess with them or wont stick where they are supposed to. That itself will cause an air leak.
