Is there an upgrade for heater motors? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The old heater motors are not that great. Has anyone got better ideas for stronger, better, quieter motors? Do the switches make a difference?

I upgraded mine a while back. Blows like a madman. I think it was referenced in this thread:http://67-72chevytrucks.com/vboard/s...d.php?t=166446.
I up the amps on the fuse as described.

That thread says it only works for the AC equiped trucks... any other options?

I dunno how they could be better. I've been driving these trucks for 40 years and always felt the heaters work great. I can't count all the times people have ridden in one of my trucks and commented on how good the heat was. I can't tell you the last time I ever scraped my windshield. I just start it up and in no time even thick ice is off the windows. The heat in my '92 is what sucks. I always wondered if others felt the same. Can't keep the windshield clear of slush worth a squat.

I saw somewhere in heater threads about a blower motor that you can buy from Auto Zone that fits right in and requires a 20 amp fuse also.. no a/c. I bought one, around 26 bucks. I'm going to install it Sunday and will let you know what I think. My original motor still works and does heat up truck, although high speed seems like 2nd speed in newer autos so I'm just looking for a boost in speed. I'm also installing new gasket kit, new cables and a new heater resister while I'm there. That blower motor is a VDO part number PM102...As for the thread, they said it fits right in, I'm going to use my old fan.

it's not the motor it's the cage, g.m. made two.. that fit.. one moves more air..
can't remember what they are off of. but I wanna say burb's and vans that have big areas to heat

Thanks for all the info,
I should have noted that I have heat but need more air flow.
