so, i know we have tossed around the subject before... ive done a few searches on here and google but havent found anyone that did a different blower. theres people asking about any upgrade, people telling them to check their vent flaps but nobody with an actual swap. ive heard from you guys that you heard someone that did a crown vic blower. before i go and spend money id like to know what will work. i was lookin at my dads psd blower, looks pretty close. about the same size, ill have to wait til he goes outta town in my moms car so i can tear it apart and see if it will fit in my box lol. one guy said something about running a different relay. said having better voltage made a world of a difference in the speed. might hook up a 12v supply straight to it to see if that does anything. if not, ill look around for something else. any ideas would be good....

 

Going for a stronger air flow from the a/c?

I just picked up a new replacement blower for mine because the blower was making more noise than my 4" straight piped engine! lol

 

I have mine hooked up dicerct thru a toggle now and it made no diff in the speed. I think it was greystreak on in the big bronco furum that said something about the squirrel cage fans on newer trucks/cars being a better design.

 

mine is new. the old one was crappy so i got this one from autozone when i got the truck. was exactly the same output

 

The trick is to improve the ground to the blower. I have a ground wire going directly from my battery to my blower fan motor. That really made a world of difference in fan speed.

Next, I set up a relay with a big hot going straight to the battery to the fan. Everything works normally but I have a "turbo" fan toggle switch to throw the relay and run the fan directly off of the battery.

These 2 changes together, give fan speeds comparable to a modern vehicle. Maybe not quite as good, but I will put it this way, I stayed cool all day in it in 107 degree temps last week, and its a super cab with bad weather stripping.

Let me know if you want any specifics on this or have any questions.

 

roll the windows down..lol

 

RIGHT ON!!!!!!! LOL po po oreo.........

 

How does that help when its 120 degrees outside?

 

lol i couldent resist...thats what i do.
have you checked to see if your getting a full 14 volts (or whatever your truck charges at) to the blower when the truck is running?

 

I've got this on my list of wants. It wasn't so bad in southern Illinois, but in San Antonio, it's a good 30 minutes of highway driving to get the cabin temp to bareable. On high it blows about as hard as my 2010 Outback does on low. Well, maybe it blows that hard.

 

I had the same problem with mine. Tried a couple different fan motors, neither helped much. One day I was messing around under the hood while it was running with the ac on high when I felt cold air blowing on the back of my hand. A closer look and I discovered my air box was leaking at the seams and about half my air was blowing out under the hood. Sealed up all the leaks and now my AC works great. Check for air leaks around the air box.

 

i know its common for the damper to hang up and not close all the way, also check the foam seals like galute mentioned above

 

I have to ask, how did you do that blower motor mod? I am very interested in this!

 

I'm a huge fan of the roll down the windows myself, much to the dismay of my passengers. I will admit in the year I've owned my truck, I've used the A/C twice. It was about 130, and I was towing a trailer during the summer, freaking broiling up that mountain road.

 

i agree, i finally recharged mine, now i hardly use it
