Buy a blower for like a 94-95 chevy silverado. Install it in place of yours, its easy just 5 bolts.

Voila! Blows so much harder. Thank me after the job when youre enjoying your dr pepper.

Are you sure it's the blower that made the improvement, or could it have been that you improved the motor ground connection, which is a common failure area for these motors? Just asking, not trying to stir the pot.

Love the VDO decal, to make you think you're getting quality German parts, and then the "made in China" at the bottom. I'm sooooo friggin' sick of this.

Nope its the blower. But you do need to make sure you scrape the paint away for that ground

Pretty sweet little mod then, especially for a us cavernous Suburban owners. Although since fixing my melted HVAC switch, relaying the a/c clutch, and fixing the ground to the blower, it gets almost too cold in there with the front and rear a/c units just on low speed.

Mine is pretty weak at best. I'm definitely going to try this! Thanks!

I've heard this before too. Not sure if it's higher rpm, or more windings with more power or what, but I've heard it's about a 25% increase over the OEM square blower. For anyone who wants to try it, the last blower motor I got was from Pull A Part, I walked all the squares til I seen 2 that looked like they have been replaced recently. You can tell by how clean they are, and bought it for like $8. I was able to test it on a battery they had there on the way out before I paid for it. So next time I know, get a clean new looking blower motor off a GMT400 truck instead. Also, same with the starter on 95 and up, or is it 96 and up, that get the high torque gear reducted starter? At any rate, these are 2 good upgrades we can do to our squares off of GMT400 body style trucks.

that trick will work for a ac cab truck, i tried it for the heat aspect of it and it does not fit into a non ac , the ac one is longer, there is a huge differance in the amount of air it does move bacause i plugged it in and ran it just to see if there was a differance
