Heater Stopped Working: How 1A Auto Helped Me Fix My Chevy Truck’s Blower Motor Problems

I have a 2003 Chevy Avalanche 1500 and the fan abruptly stopped working for both heat and A/C. I know just enough about cars to be dangerous. So when the heat went out on my Chevy Avalanche that I purchased a week before, I knew I wanted to fix it myself. Turns out it’s common to have a Chevy truck with blower motor problems.

Disclaimer: That is definitely not me featured in the video above.

Diagnosing the Cause of my Chevy Truck Heat Failure

Trying to diagnose why the heater stopped blowing air, I turned to 1A Auto. I read an article on the 1A Blog about A/C failure. It was a thorough article on generic A/C issues but also covered when the fan stops working entirely, so I thought I could get some insight.

After removing the blower motor, I confirmed about 12v coming out of a 2-pin connector. I also hooked the motor directly to the battery and the fan started spinning, so I knew the problem wasn’t the blower motor. I didn’t have a way to test amps going through the wire when I changed the resistance. At this point, I assumed the problem was with the control panel but wasn’t sure how to troubleshoot it.

6 Things Shady Mechanics Don’t Want You to Know

A trusted mechanic can be a great resource for car repairs. “Trusted” is the key word there. As with any business, there are some mechanics who will put a quick buck ahead of what’s best for you, the customer. We’ve pretty much all dealt with someone like that at some point. The best way to protect yourself is by educating yourself so you can make more of your own decisions. Here are some things you should know, even if your mechanic doesn’t want you to.

1. They Don’t Have Automotive ESP

Mechanics don’t have psychic powers that tell them what’s wrong with your car. You can apply some of the same skills the pros use to diagnose your own problems. A good mechanic knows plenty of tests to find out what went wrong with your car, and although you may not reach the level of expertise of a pro mechanic, you can definitely learn some basic tests.

First, if your check engine light comes on, a mechanic will use a device called an OBD scanner to check for trouble codes that will point out the problem. You don’t have to take your car to a shop to get it scanned, though. Many parts stores will rent you a scanner, or you can buy one, sometimes for as low as $20. If you have an older car with frequent problems, an OBD scanner can be a good investment.

You can also learn how to test parts for wear and tear yourself. You can easily visually inspect brakes for wear and you can test suspension parts like hubs and struts by hand.

In some cases, your shop is just trying to figure out your problem by educated trial and error. They may try one part see if it works, and move on from there. Of course, with a little know-how about your car’s various parts and symptoms, you could do your own process of trial and error much cheaper, as our DJ Butler describes. No, it’s not the ideal way to fix your car, but sometimes it’s your least worst option. Read More

The new year brings a new opportunity for some lasting changes. While it’s always a good idea to work on ourselves, working on our cars can also set you up to have a great year.

Tackle basic repairs

There are plenty of easy repairs you can do that only take minutes. Changing windshield wiper blades, filters, spark plugs, and on some cars the headlights and tail lights, are so easy you’ll wonder why you ever paid to have them done for you to begin with.

Do I Really Need to Warm Up My Car?

If you live in a cold climate, you’ve probably heard how essential it is to let your engine warm up before driving.  You might even be in the habit yourself.  But is it really necessary?

It turns out that there’s a lot of debate on that subject. Some say letting the engine warm up will make it run better and will reduce engine wear. Others say that leaving the car idling in the driveway wastes gas and is bad for the environment. Of course, some people just don’t like to sit in a cold car.

The Case Against Warming Up Your Car

The Environmental Protection Agency does not want you idling your car much.  Their primary concern is the carbon dioxide and other exhaust gasses that the car gives off while idling.  The engine is also at its least efficient when it’s idling.  It’s using gas without going anywhere, so, as Chris M0oney at the Washington Post points out, you’re getting 0 miles per gallon.  The engine also tends to run richer, using more gas, when it’s cold.  Over time that puts a hit on your wallet.  The rich running can also put more strain on your catalytic converter, which might mean you have to replace it sooner.

Gifts for Car Lovers, Mechanics, & Your Favorite Car Guy

Holiday gift guide: Gifts for every car enthusiast on your list!

Do you have someone on your Christmas list who’s crazy about cars? A Dad who’s into classics, an uncle who’s an off-roader, a brother who’s a wannabe racer, or even a kid who likes to crash his Matchbox cars? This post has gifts for car lovers of all types this holiday season.

Some of the gifts included in this list can be purchased from 1A Auto. However, there are many included that you can buy from another online retailer, such as Amazon or Gamestop.

Gifts for Classic Car Lovers

People who collect classic cars get really attached to them, and why not? Those designs were timeless and bring back a lot of memories. If you know a car enthusiast with a cool classic, why not help them keep it in tip top shape with a new car cover? A car cover can protect the exterior of the car, and a new set of floor mats can help protect the interior.

Some classics are meant to be kept pristine; others beg to be remade in the owner’s image. A custom shift knob is a fun way to spice up the interior of any classic or hot-rod. Skulls are always in fashion, but there’s lots of other options.

Or maybe your mechanic uncle talks wistfully about the one that got away. My Dad had a ’67 Riviera and ’64 Impala back in the day. I have to say, I’m pretty jealous. Since American muscle is a little bit outside my budget, the old man might have to settle for reminiscing vicariously. My Dad Had that Car is a book of photos brochures, and other pieces of automotive history.

Unique Gifts for Car Racers

If you know someone who wishes they were a racing driver, you’ll want to give them some safe ways to indulge their need for speed. There are a lot of great racing games out now, from Gran Turismo Sport, to Forza Horizon 3, to, yes, a new Need for Speed game, Need for Speed: Payback.
