Boost your trucks A/C in 20 minutes.

Replace your blower unit located on passenger side with one from a 95 silverado. Wow does it blow better! I get much more air from the vents now. 5 little bolts and a power wire.

Make sure you scrape off the paint for the ground. This thing was cheap too. Like 15 bucks.

Really that much better huh? What years will it fit? Would it fit a 77 3/4 ton? What's the part number?

hrm..... might have to be something i knock out before the weather gets cold and see how well it works haha. Id have to recharge my AC i think i have a small leak since it only lasts about 4-5 months depending on how long the truck sits

It's great to do in non a/c trucks too.

I will check with the experts at Century Auto Air Conditioning and see if there are any others that will interchange.

Thanks for the tip.

[SilverMiner]

Yes, please give us some part numbers! NAPA and/or Rockauto numbers would be most useful in my instance, or even just tell us more specifics about the 95 Silverado.

Same here. I want to do what a few threads here say to do as far as cleaning out my air ducts and all the vents and combined with a stronger blowing motor it should be awesome. I need to do this to my wife's 77 3/4 ton cause the air is cold, and sounds like its blowing real hard on high, but there's not alot of strong air coming out, like its only on medium. I'm sure being a 77 and never probably having the ducts and all cleaned out is the reason. People here who have cleaned there's out say there was a HECK of a difference in air flow afterwards.

No time like the present to try it yourself!

Could I get some updates from you guys regarding this fan change?

I am getting closer to removing and replacing mine.

I could really use the faster fan speed.

It's the same motor. Your old one was just wore out and shot.

I was going to ask what the difference really was. I was thinking that maybe the later model motors pulled more power or something.

[tucsonjwt]

Just curious, what is the difference between the two motors? Is it possible that you just had a weak original motor and an fresh new motor made the difference - both motors having the same specifications?

[Desert1957]

I do not understand this thread?

Just looked up my 87 R10 and my 83 C20 VS the 95 Suburban you listed on "Rock Auto"
calls for the same GM part number 1580213 , What gives?????

I have nothing good to add to this thread so its been edited by moderator

Example: if this fan you put in was some super powerful fan that drew a ton of amps, hooking it up to the stock wiring could cause a fire. And I, as I'm sure many would agree, that "it just is" is not an acceptable answer when asking why something is better.

The way you talked of this new fan, leads the reader to believe the 95 Silverado fan is a better fan is a better fan than any other 73-87 fan, when it's not. In fact, it's the same fan. And I doubt that the autozone Made In China fan is any better, in any way, to a new GM fan.

Very true, details do matter...especially in electrical components! It is the same blower motor, and it probably does a better job and moving air because it's new. This particular blower motor is very common part that is used in many make & models besides GM. I recently replaced the same part in my '79 GMC as well, and it does seem to boost the airflow... but I also replaced the blower motor resistor because the high speed coil was burnt out. I figure that had more to do with the airspeed... Haha!

Recently I replaced the AC blower motor in my '76 GMC with a VDO unit similar to that shown in the original post. It works great. I paid $21.99 from O'Reilly (part number VDO PM102) and that even includes a lifetime replacement warranty. I re-used the original plastic fan part as there was no reason to replace it. Now there are some important details to consider when changing out this component. First, be sure the plastic fan unit is cleaned and well-balanced when installed on the new motor. Next - VERY important - as mentioned above make certain that you have a clean, bare metal ground connection to the flange at the base of the blower motor. Also, I used 3M strip caulking to re-seal the unit to the blower housing. Be careful not to over-tighten the attach screws as they can easily be stripped out. I want to go on record to say that I always prefer to use "made in USA" parts. The reality is that this is not always possible. Even Delco now buys a large percentage of their products from non-US sources. Sad but true.

Yeah the way the thread was written, i was under the assumption that there was a difference between the stock motor and the one made for a 95. They seemed like the same blower motor to me so i couldnt figure out what was so much better about the 95 either.

[Skunksmash]

Somewhere on there, there are probably stamped or stickered specifications. Somebody needs to compare 'em
