Is it possible to add A/C Vents to non A/C Blazer - The 1947 - Present Chevrolet & GMC Truck Message Board Network

slamd58 · 01-02-2005, 01:19 AM

Is it possible to add the vents for A/C to a Blazer that didn't have them? The Blazer in Tacoma that I am looking at does not have A/C and the vents are not there. The side vents look like that are pretty easy to add, however the center vent looks like it needs to be cut out and the vent added. Can this be done?

Scrubby · 01-02-2005, 01:28 AM

I think this can be done a couple ways. One way is you can cut the dash out of a A/C truck and weld it into yours. I have also seen templates that tell you were to cut the holes for the A/C vents. In both cases you would need all the A/C ducting and parts to go behind the holes in the dash.

Chevy Muscle · 01-02-2005, 11:13 AM

I made templates from an A/C truck and then cut the holes in my dash. I took my time and it turned out very well.

I would say that the center section is the easiest part to cut since all the cuts are straight. The side vents are pear-shaped and not easy to cut perfectly. I used a smaller hole saw then a die-grinder to make the proper shape.

Good luck and you will also have to modify the firewall if you are going to use a stock A/C airbox.

You will also have to modify the firewall if you are going with factory ac, this would involve welding up one of the airbox holes and cutting a new one.

bouncytruck · 01-02-2005, 02:20 PM

I have an article in one of my magazines that shows how to add AC. I'll see if I can find it and try to scan it. It is an old air product they add, but the vents are almost the same and in the same location.

You will also need to add an AC battery tray and and AC glove box. Hopefully that truck already has a 4 core radiator, but if not, you will need to put one in, especially with the summer heat in K-falls.

There are some under dash AC systems that are good options too. They look like the dealer installed AC systems and don't require as much modification.

Since that truck is at a dealership. I would totally low ball them. It is probably either on consignment or someone traded it in and didn't get anywhere near $20K for it.

red71cheyenne · 01-02-2005, 05:56 PM

Totally agree, both on adding a/c and low balling the dealership. You also will have to buy the inside recirc vacuum actuator and flapper valve inside the cowl. I think if I was doing it though, I would go with a new setup from vintage air or one of the other vendors as it already is set up for R134A and will run the compressor on the defrost cycle. If I decide add A/C to my K5, thats the route I'm going to go. Jeff.

NOT DENYING YOURS KEITH, JUST TELLING HIM WHAT MY PO DID, HE
WAS TALKING ABOUT SWITCHING OUT THE ENTIRE DASH, MINE WAS

71swb4x4 · 01-02-2005, 07:08 PM

If you don't necessarily need factory air, cut the dash for the factory vents, and then add a unit from Vintage Air or the other aftermarket AC companies. Then you would not have to modify the firewall, but to most it would look like it was there from the factory.

slamd58 · 01-02-2005, 08:54 PM

Thanks for the info guys! I had a vintage air unit in my '58. It was pretty trick, although I'm not sure if it was set up correctly, because the A/C did not get that cold. The heater worked awesome, but the you could barely feel the air coming out of the dash vents. I am getting closer to making a decision and will let you know how everything proceeds. Will definitely low ball the dealer if I go that route. He probably gave the guy 10K - 12K as a trade in.... maybe less

There is a nice looking ochre blazer on ebay right now. A little farther away, but it is bone stock.

Bouncy - forgive my ignorance but what is an ochre blazer. this is the second time I have heard this and have no clue what it means..

..Is it the color?

bouncytruck · 01-03-2005, 12:16 PM

Ochre is a mustard-yellow-orange color. Some people love the color, others hate it. Personally, I like it, but I like my orange K5 better.

from dictionary.com
o·chre or o·cher (n.)

1. Any of several earthy mineral oxides of iron occurring in yellow, brown, or red and used as pigments.
2. A moderate orange yellow, from moderate or deep orange to moderate or strong yellow.

Dragonslayer · 01-03-2005, 12:41 PM

I just got started this weekend with my restoration. I am seriously thinking about doing the same thing. It looks like I can get just everything I need from LMC Truck (ducts, vents, hoses, compressor). If you get around to doing it, I would be interested in knowing what it took and how hard it was. I am interested in staying with the stock system that originally came with the Blazers.

Thanks, I resemble that remark. I am indeed a geek!

Just some clarifications---1. The Blazer/Jimmy came with both under dash and in dash radio speakers---just depends on the year---. Jamie and I parted out several this past year and every one was an original in dash speaker.
2. Converting a non-AC Blazer/truck to original AC is doable and not terribly difficult butttttt---it's probably going to cost more then an aftermarket by the time you're finished. Original A/C works well when correct but--can be a pain to maintain as some original parts are becoming rare and the compressor is an antique suckin lots of power and space. Consider an aftermarket--be it vintage, old air or ??? They are far more efficient and if working as designed, they are at least at good --better then the original. Plenty of manufacturer support available. Take up a lot less space and power. If done well, you can't tell without looking under the dash or under the hood. In my limited mind, cool is as cool does!!
