Archive for July 2024Such a Little Part (Climate Control Resistor)Posted July 28, 2024 4:58 AMYou expect your heater/air conditioner to work like it should. You have a control for temperature and one for fan speed. You even have a control for what vents the air comes out of. Don't be surprised one day if your blower fan develops a mind of its own and starts going crazy. Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good. This is what may be happening. Your blower motor has an electronic component called a resistor. It does what its name says; it offers resistance. When you want the fan to run more slowly, you turn the fan speed down. That resistor accomplishes that by turning its resistance up. When the resistor fails, the power has nothing to slow it and the fan speeds up. It's a small part and can fail due to age or corrosion. It's usually not an expensive part, either, but it's often found in a location that's not that easy for the technician to get to. That means labor costs will vary depending on the design of your vehicle. Occasionally, a faulty resistor can cause the blower motor not to work at all or only partially come on. But other things can cause that as well, such as a faulty fan switch or vent control. This is where a technician's training comes in. Special equipment can track down precisely where the issue is so you can be assured the correct part is being replaced. It's just not pleasant when the blower motor isn't following orders. Have your service facility check it out so you can be the blower's boss, like it should be. Franklin Auto Service Snake in the Engine (Serpentine Belt)Posted July 21, 2024 4:57 AMThere's a belt that snakes through your engine. It's even named for a snake, the serpentine belt. It'll bite you when it breaks, possibly leaving you stranded. So, it's good to know a little about this snake-like belt. In early engines, there were lots of belts. They were used to convert the rotating power of the engine to turn a mechanical part. But engineers had an idea. Why not consolidate all those belts into one that ran a bunch of different parts simultaneously? Voila! The serpentine belt. It's found in the front or side of your engine unlike older belts which were often in a V shape, the serpentine belt has ribs on it which more effectively connect with the pulleys that power the other components. A serpentine belt may power the water pump, power steering pump, alternator, and the air conditioning: all from one crankshaft. Now, all that's fine when everything is working well and the belt is intact. But when a serpentine belt wears, gets loose, or breaks, it can affect many engine components at once. Not an ideal situation. If you hear squeals coming from the engine compartment, see a battery light, or the engine overheats, those could be signs that your serpentine belt needs replacing. The good news is that they usually last a long time, from 60,000-100,000 miles or 100,000-160,000 km. Still, they don't last forever, and your vehicle's manufacturer usually recommends replacing them when they've gone close to the expected maximum. It’s also recommended that you replace the pulleys and belt tensioner at the same time as they have the same service life. Regular maintenance and inspection of the serpentine belt is not only a good idea; it’s one of those things that you should not let "slip" by. Franklin Auto Service The Daily Grind (Grinding Noise)Posted July 14, 2024 6:24 AMIf your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you. No, really, it is. So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on. One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels. Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. Think of it. Hydraulic power steering has many components that need to work in tandem. The power steering fluid may be too old and contaminated. Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front. You may have a failing CV (constant velocity) joint. It could be your brakes are partially engaging while you are turning. That metal-on-metal sound is never a sign that things are working just the way they're supposed to. To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all. Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared! Franklin Auto Service Keeping Your Cool (Water Pump Replacement)Posted July 7, 2024 6:25 AMNo matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected. Well, cool, anyway. If your vehicle has a gasoline engine, it's powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air. And the by-product of all those things working together? HEAT. There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump. Technically, it's pumping more than water. It should actually be called the "coolant" pump since the liquid that circulates through the system is a mixture of water and coolant. Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat. When a water pump fails, the engine heat can build up. When you get a warning light on the dash (either a gauge or a light) that shows the temperature is too high, it could mean a bad water pump. They can fail for many reasons. They have bearings in them that wear out, as does the seal between the pump and the engine. They're often driven by a belt or chain that can go bad. Corrosion can spell the end of a water pump, too. If a technician determines your water pump has failed, it's time to replace it. In addition, other components of the cooling system will be inspected. The best way to avoid a water pump failure is regular maintenance of your cooling system which includes regular draining and flushing of the coolant. Just like it's important for you to keep your cool, the same goes for your vehicle's engine. Franklin Auto Service | ||

We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!
My vehicle broke down right in the middle of Maple and Telegraph. Called tow truck company and as I waited I googled auto repair shops near by. Franklin Autos had the highest reviews and was close by. The reviews were well deserved! Fixed my car at a very fair price and while I was scrambling with Uber to get back home the owner was intuitive and generous enough to say "you want a loaner"! In this day and age WoW-good work, fair price and empathy has my business for as long as I am in MI.
