Time Lapse Video of Evaporator Restoration

From our friends at Graveyard Carz, here is a time lapse video showing the disassembly and re-assembly of a rare 1971 Dodge Challenger R/T Evaporator Housing.

High Blower Speed

In September, we discussed why you should keep your original factory A/C system. But what if it’s not working?

One common issue is that a fan doesn’t reach full capacity, yet all other speeds work. Most people assume the fan switch is bad, but in reality, the cause is usually a bad blower relay. The switch doesn’t control the high speed, it controls the relay which then activates high speed.

While fan switches can eventually fail, typically they never do on their own. If a fan switch does burn out (due to a loose terminal, there are burn marks on its back, or loses any speed other than high) it’s typically the result of a deteriorating blower motor which is drawing high amperage (or a bad ground connection to the motor).

The same is the case with resistors and relays. If a resistor has a coil burn out or any terminals loose, it’s likely the blower motor. Replacing any of those components without changing or repairing the blower motor may fix the issue temporarily. However, this will only cause the newly installed parts to fail again.

So before you order any new parts for a fan that does not reach high speed, remember to check the blower motor and connections first.

Fall Inspection Checklist


October is Fall Car Care Month 

Get your vehicle ready for cooler temperatures this October.
 Preventative maintenance leads to fewer unexpected repairs.


Inspection Check List:

Heating, ventilating and air conditioning- Proper heating performance is just as important as proper cooling performance – keep in mind that we are the A/C and heating industry leader and have the largest inventory of used original parts in the business!

Exhaust system- Be aware of leaks and damage to assure harmful fumes do not enter the vehicle.

Hoses and Belts- Check for cracks, bubbles and bulges in your hoses. Don’t risk being stranded on a highway with a broken down car. Read more about replacing hoses here: https://www.originalair.com/when-should-i-replace-my-hoses

Brake System- Have brake system inspected now, especially if you will be driving in more intense weather this winter.

FluidsCheck your engine oil, coolant, power steering fluid, brake fluid and windshield washer fluid.

Lighting Check exterior lights frequently. Look for cracks, burnt out bulbs and dimmed lights.

BatteryLook for corrosion, leaking and swelling in your battery. The connection should be tight and free of corrosion.

TiresInspect tread on all four tires as well as tire pressure. Ensure your wheels are aligned and check for any bulging, cracks or bald areas.

WipersEnsure your wipers are not worn down. This will be important should you drive through any inclement weather.



Why Keep Your Original Factory A/C System?

We know you have thought about it when planning to restore or modify your classic car or truck - "Should I keep this factory A/C system?"  We get emails and calls all the time as owners seek validation for keeping their classic system and the costs to maintain.  Well, if you ever wondered, here are a couple things to keep in mind:

  • It’s cool.  Literally!  Since many classic cars and truck did not come with factory air-conditioning, and even those that did were often stripped of key parts at some point in its life, having a classic with factory air-conditioning helps it to stand out from the crowd.  Especially if it’s functioning and kicking cool air.
  • Resale value.  Having the original functioning factory air-conditioning has proven to help increase resale value.  It can also help your car sell ahead of one without factory air conditioning.
  • There are still options for getting it fixed, and in some cases, more efficient.  Original Air offers customer rebuilding & fabrication services for many parts for your classic.  We also manufacture model specific (and sometimes custom) parallel-flow condensers, sell model specific Stage-1, 2 & 3 A/C performance upgrade kits designed to improve the factory air-conditioning.
  • No need to modify your car.  Many aftermarket air-conditioning systems require some sort of modification to the vehicle and may not fit as well as the factory engineered system 

So, don't think about it!  If you have a factory A/C car or truck, keep it and enjoy the benefits of being cool.

Reader Ride: Andy's 1971 Chevrolet C10 350

This truck was my grandfathers. He gave it to me shortly before he passed away. My father actually sold it to him sometime around 1977 so it has been in our family for many years. Grandpa drove it daily to work for quite some time until he retired. From there it became a work truck. Used for pretty much anything you can use a truck for.

I have had the truck since 1995 and used it as my daily driver for more than 15 years. I was always amazed at how reliable it was. When my last child graduated from high school I began to seriously think about rebuilding it. At first I thought I would just fix the rusted parts and paint it. But I soon realized that wouldn't be good enough. As I took parts off the truck I saw that there was much more deterioration than expected. So I did the only thing a car guy can think of, complete restoration!

The project has taken close to 7 years from disassembly to completion. Well, are we ever really done with our classics? At any rate, I have endeavored to stay as original as possible. I have repaired over replace as much as possible. I had to replace the entire floor pan, pillars and cab corners. And instead of repairing the factory air conditioning I opted for cleaning up the firewall and installing an aftermarket A/C system. And instead of the bench seat I chose to install power bucket seats from a 1997 Suburban. But, I was able to make them look similar to the factory option. I also put in the center console from a 1972 Chevy C10. I liked that style because it has cup holders instead of the slots for the seat belts.

The motor is the original 4 bolt main small block 350. I installed a moderate cam, flat top pistons, headers, and an HEI distributor with an external coil so that it sill looks stock. It has the original quadrajet, that I still need to modify so that it can support the changes to the motor. I also rebuilt the TH350 transmission. I did farm out the rebuild of the 3.08 rear end. I had the frame powder coated and rebuilt or refurbished every piece of sheet metal on the truck. I even went so far as to straighten and clean all of the original trim. All of the bed walls, fenders, etc have been cut apart and cleaned of rust and treated with bed liner. All of this was done in a two car garage, including the painting.

It has been an absolute labor of love that at times I never thought would be done. For over 5 years every weekend and some weeknights were consumed with this project. There are still some things I want to do to improve the performance. But as of this weekend the tailgate will go on the truck marking "completion" of the project. Unfortunately my father and grandfather are not around to see the final result. But my step-father is and he has helped me immensely. While this project at times has been difficult, even grueling, I would do it again in a heart beat. Just not in an attached two car garage!!!

Reader Ride: Dave's 1973 Chevy Nova

Many thanks to Dave Keillor for sharing his beautiful Chevy Nova with us!

Our Nova is a low-mileage car that was originally sold in North Carolina.  It came with factory air and I recently upgraded to a R-134a system from Original Air.  The new system is great!  Mid-30s from the center vent and plenty of cool for the hottest days.  The folks at Classic Auto Air's Original Air Group were great!

Questions To Ask Before A Classic Car Purchase


We all know the basic questions to ask when buying a car. Is the title clean, does anything not work etc. You know the deal. But there are few different kind of question to ask when purchasing a classic. This is simply due to the fact that you're purchasing a 25 to 50 year old vehicle. Here are a few things to think about before having your name put on the title. 


Is There Rust Anywhere? This is a big one. Don't just ask though. Make sure to get under the car with a flashlight and inspect for yourself. Some rust is to be expected, but you'll be able to tell hazardous

Is The Car Currently Registered? If Not When Was It Last? This will give you a great indication of how long the car has been sitting. And if it has been sitting, was it garage kept? Find out!

How Long Have You Owned The Car? This is one you may ask anyway, but if not it's a great way to weed out how many times this car may have been flipped by other dealers. The longer they've owned the vehicle, the better.

Why Are You Selling? Another basic question, but an important one. This should be one of the first things you ask as it could lead to many important facts about the car. Maybe it needs work, the upkeep has been to expensive or they would just rather have the money. Hopefully you get an answer that's more of the latter. 



Don't be afraid or feel rude about bringing your own personal inspector to give the car a really thorough look through. You can typically bribe your local mechanic who’s been in the game for a while to come with you if you throw him 50 or 100 bucks for his time. Good luck on your next purchase.
