In the Hot Seat (Repair and Maintenance of Seat Heaters)

It’s chilly outside. You flip on that switch that looks like a picture of a seat with little heat waves rising from it.  You expect soon you’ll feel that warmth but… wait! It’s not getting warmer.  Oh no, what’s wrong with my seat heater? There could be lots of reasons it’s not working, and it could be as simple as a fuse or as major as the heating element itself.  But it’s something to leave to a pro to diagnose and repair.

Let’s say it turns out to be a blown fuse.  Simply replacing the fuse may not fix it because there was a reason the fuse blew in the first place.  It’s possible the on-off switch has worn out or corroded.  Perhaps the wiring connection isn’t completing the circuit (could be corroded or full of dirt) or the voltage reaching the heating element isn’t correct. 

There’s a little sensor that keeps track of the seat heater’s temperature called the thermistor.  When the seat is hot enough, it will stop the juice from heating it any more.  Sometimes those fail.  But if all of these components are healthy, you may need a new heater element. 

Those seat-heating elements are made up of wires that get sat on.  A lot.  That can put significant strain on them.  Putting something heavy on the seat can break them. Or, if you put your knees on the seat cushion as you’re getting something in a rear seat, that can also damage the element.  Sometimes they can be repaired but often they have to be replaced.  And here is where the technician’s expertise comes into play.  That heater element is attached to the seat’s fabric and replacing it can be tricky.  It also can require disassembling a lot of the seat to access it. 

Seat heaters are a wonderful feature and they make your vehicle oh, so much cozier.  So keep them working and enjoy the warmth!

The Autotronics of St. Peter Guide to Tire Specs

You know you need new tires, but you’re not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the St. Peter service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many St. Peter drivers. There’s so much on the side of the tire, and it’s hard to keep straight.

Even though there’s a lot on a tire – if you know what it all means, it’s actually more helpful than confusing for St. Peter tire shoppers. Let’s start with the size number.

For example, let’s say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters – the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio – the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it’s a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index – it’s the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty vehicle can be safe with a lower number, but you’ll need a higher rating if you routinely haul heavy loads around St. Peter. The next letter is the speed rating. Not all tires sold in St. Peter are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating – with the exception of H – it comes between U and V (don’t ask why).

There’s a lot of fine print that most St. Peter area drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there are the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line – a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the manufacturers product line – you can’t compare with others. And it’s important to note that a lower rating might be just what you want – a high performance, sticky tire has a softer rubber compound and won’t wear as long, but boy, will it take those corners on twisting MN roads.

The next is a traction grade. This measures the tire’s ability to stop on wet pavement in government tests. A – the best, B – intermediate, C – acceptable.

Temperature grade measures a tire’s resistance to heat buildup in government tests. A, B and C – from best to acceptable.

It’s safe for St. Peter drivers to go with the vehicle manufacturers original equipment recommendations that came on your car. But if you want to make adjustments, you’ll now be better equipped to communicate with your friendly and knowledgeable Autotronics of St. Peter tire professional.

St. Peter Customer Detective Work

One might say the most challenging part of being an automotive service technician at Autotronics of St. Peter is diagnosing a problem before it can be fixed.

Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it’s challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it’s not something obvious, it’s easy for the customer to focus on the fixing and not the diagnosing.

Let us at Autotronics of St. Peter introduce you to something we’ll call ‘Customer Detective Work’ –  helping your technician find clues to what’s wrong.

We start with the detective basics: What, Where and When. Play along with me; You come in to Autotronics of St. Peter and your car is making a funny sound…

    • Q: Where’s the sound?
    • A: Around the right front wheel.
    • Q: What kind of sound?
    • A: Kind of a clunk, clunk sound.
    • Q: When do you hear the sound?
    • A: When I turn and accelerate. 
  • Q: Right and left? Forward and back?

Do you see where we’re going? You’re gathering additional information to help your technician at Autotronics of St. Peter know where to start. Based on your car and the tech’s experience, he’ll know where to look and can start with the obvious suspects.

You can see how that would be more helpful than dropping the car off with a note that says “making a funny noise.”

If the tech can experience the problem personally, he’s better able to make a diagnosis and repair and then test to see if the repair solved the problem.
