Re: GM labeled under dash air conditioning dealer installed???

In 1972 my uncle order a new Cheyenne with all the options except A/C. He did this on purpose so he could install an aftermarket unit made in Oklahoma City. (I cannot for the life of me remember the name) The unit was really thin and went all the way across the bottom of the dash and it really was better than the factory unit in performance as it could move more air around the cab without the direct blast effect from the factory vents.

Re: GM labeled under dash air conditioning dealer installed???

Is it working now? If it was me, I'd keep it if it worked or was all there and just needed servicing. I see a way cool factor over using the ez peezy (but not so cheap) modern system people expect to see.
I never saw this thread back in '11. My '70 CST Blazer had this dealer accessory. Not sure why people call them dealer installed when we have no idea who installed each unit. Most likely not the dealer in most cases. Dealers tended to shock people with shop bills. I've known of people insisting an the factory 4 season system being upfitted to a truck that came through w/o it. I bought my '70 Blazer from the original owner. He had bought and installed the system himself. You will find different levels of quality on installation. Fortunately my previous owner had done a nice clean job. I had a parts Blazer with one and there was funky foam seal all over the place, including at the firewall where heater box meets it.
Who knows a value on anything you seldom see sold? It's what the seller wants and a buyer will pay. I don't see hoards running out to find these, but as with many other things, that day could happen over night. First comes being made aware they exist, then seeing the right person have one or seeing one in the right truck. They are actually quite cool, just as any era GM accessory is. For that matter, any aftermarket A/C unit that chills the cab is cool in my book. That's not a pun

Re: GM labeled under dash air conditioning dealer installed???

I was searching for A/C info and stumbled upon this old post...but it was the closest match to what I have. My story is that I purchased my Suburban from the original owner (who is sadly no longer with us) and he was the Service Manager at a GMC/Chevrolet dealership for close to 45 years...although during our conversations, he had trouble remembering specifics concerning when and what was done to the Suburban throughout the years. Additions were done at the dealership, but I don't know if that actually qualifies as "Dealer Installed"...but my A/C unit fits like it was made for the Burb, and didn't require any mods to the "glove box", heater or any other areas. It doesn't have the small "GM" insignia, but does have an embossed area where there was a name plate (missing, but possibly Chevrolet?). Everything is functional except that it will not hold refrigerant for very long, but I believe the leak to be in the extremely long lines that go to the rear over head A/C unit. My plan is to block off the tees under the hood to isolate the two units, then focus on the front under dash unit before moving on to the rear unit repairs.

My questions are: Does this unit look like a "Dealer" option...maybe from a Square body, given that he worked at the dealership for so many years...and would '73 and up fit the '67 to '72 models this well? Thanks for any info.

Woody

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Re: GM labeled under dash air conditioning dealer installed???

For Beach-Burban,

Your underdash setup could very well be a dealer installed item as every photo in this thread seems different. I did considerable research on my unit and while it does not appear on the build sheet (still inside on the glovebox lid) I believe mine was installed at the dealer. Guess they used factory a/c parts when doing the install. Anyway, the engine bay looks factory. Had mine converted to R143 when I replaced the new compressor 5 years ago. Otherwise cools efficiently. I am still looking for an owner's manual for the Harrison Unit.

Thanks nac46...there does seem to be a lot of variants out there! I'm hoping this one does the job, then I'll dress it up a little as it fits so darn well!
