GM labeled under dash air conditioning dealer installed??? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

VA72C10 · 09-14-2011, 04:30 PM

I have a guy that's contacting me about a gm under dash a/c that's in a 70? truck...he's looking to buy it and wanting to confirm

A) did dealers have a gm under dash unit they installed
B) how much would a nice working system be worth

It has the blue backed gm label on the unit under the dash and a frigidaire gm compressor under the hood.

So...anyone know if this might be the real deal?

JJchamp48 · 09-14-2011, 05:06 PM

Good question, we've got one in a 67. The truck is 1 owner all original except for driver fender, reupholstered seats and carpet. SPID shows Deluxe air heater, is that for the AC?

VA72C10 · 09-14-2011, 06:22 PM

So it has the gm tag on it? That's interesting...I had never seen one before!

**oldgold70c10** · 09-14-2011, 06:41 PM

There is a picture of the controls in the owner's manual for the under dash type. It's on page 27 if you have a copy. The 1970 accessories flyer shows a factory-installed in dash AC, and a dealer installed under dash AC.

VA72C10 · 09-14-2011, 06:44 PM

I'll check out my manuals...thanks!

Any idea of a used value?

68 SHORT-STEP'N · 09-14-2011, 07:45 PM

I don't see a GM label anywhere , but it has a/c on the spid . Just checked the compressor & it says York Automotive A Division of Borg-Warner .

VA72C10 · 09-14-2011, 09:27 PM

I think deluxe air heater just refers to the heat system. I've seen it listed with no a/c before.

The one the guy is thinking of buying has a gm emblem on the actual under dash a/c unit...

I knew there were dealer installed units and many added aftermarket under dash units...but didn't know there was a GM labeled one...

**Downtown** · 09-14-2011, 11:49 PM

This may help. I copied this from another thread. The units are black and maybe about 30 inches long. I have been watching for one for awhile.

VA72C10 · 09-15-2011, 12:10 AM

Thank you! Awesome! Do you have any idea on value for one that has all the lines and the original compressor with brackets and is working?

VA72C10 · 09-15-2011, 01:00 AM

Here's the pics I found off the link he sent me

Not the best routing for a dealer installed unit

mpotts64 · 09-15-2011, 09:19 AM

I bought a '67 lwb from a one owner for parts and it had a unit similar to the one in the pictures. The man said it was factory. I don't know, I pulled and put it on the shelf when I parted out the truck. It is pretty cool, had a square compressor that mounted on a flat bracket, not the round tube compressor like you see on many.

**71blksuper4x4** · 09-16-2011, 12:59 AM

I have seen a couple of those underdash "GM" units before. I am with Downtown and saying they were a dealer installed, but factory item. Trevor

Thanks for the confirmation.

Anyone want to guess a value? Or ever seen one sell?

68shortstep · 09-16-2011, 01:43 PM

Had a guy offer me one for my truck when I had it. All there, but laying on a shelf from a part-out he had done.

Asking $ 200 3-4 years ago. I hesitated because I knew it would need even more $$$ spent on it to make it operational, & someone else jumped on it.

Coulda - woulda - shoulda. He who hesitates has lost, etc.

I have Downtown's A/C unit in my 68 SB Fleet side. Had the system converted to 134a by the dealer, but they are unable to load freon bcuz POA valve is stuck. Does the entire system have to come out to replace the valve?

Thanks

ChevLoRay · 10-27-2011, 02:32 PM

My guess is that any "manuals" would have been installation instructions for the installer. Whatever would have been given to the customer would have been a tag/card attached to the in-cab unit. The owner's manual would have operating instructions and the shop manual would have maintenance stuff.

Before I went into the USAF in '66, I worked at a service station and we also installed Mark IV air conditioning systems into what you had. York and Tecumseh were two brands of compressors and what Ford used from the factory was quite similar. GM used the rotary and Chrysler used a V-twin compressor.

As to value, I would think that either in-dash or hang-on, if OEM and GM, would have similar value. I have the in-dash unit from my '69, in the garage. I'm not going to assign a value here, lest someone think I should post it elsewhere (classifieds). But, somewhere in the $300 range would make me happy.

71 super · 10-27-2011, 06:15 PM

Jonathon that install is pretty clean from what I have seen for dealer air. Family friend had a 70 with dealer air and they cut the top of the core support for the hoses to run through. They fixxed it of course with a piece universal strap. Complete hack job, dont think the dealer cared a whole lot. That particular truck used same under dash unit with GM label but utilized the york compressor rather than the standard GM a6 unit.

VA72C10 · 10-27-2011, 06:24 PM

I never heard back from the guy asking about this, but glad it's ended up being a "cool" and informative thread on here

67bigwindow · 11-28-2011, 08:39 PM

hey if you know or here of another mark lv under dash unit i would love to have it....i have 67 custom cab big window....second family owner ....guys grandfather bought new...any way it is a dealer air truck ..i have the original order sheet and protecto plate. i also have the mark Iv book that came with it...it includes the vin number of the truck it was installed in..ive looked around a little but most of that stuff was junked long ago. it would be nice to put it back in the truck,,,,thanks greg...

VA72C10 · 11-28-2011, 11:49 PM

I'll keep my eye out for you.

nac46 · 11-29-2011, 10:08 AM

Guys,

I do not have an additional underdash system. What I do need is the owner's manual/instruction book that goes along with it. I have converted mine over to 134a but am having trouble charging it up due to a stuck POA valve. Need help in correcting the issue. Thanks!

67bigwindow · 11-29-2011, 10:40 AM

the manual i have is simply an owners operation manual. nothing on install ...very basic...................i would love some pics of the unit you have...
