Why is my AC not blowing cold?

Why is my AC not blowing cold?

The air conditioning system in a vehicle is subjected to much more abuse than your typical household AC system.  Between the constant hot and cold cycles of the engine, the harsh vibrations over pot hole infested roads, and the constant dirt and debris there are a number of things that can go wrong.  These are just a few of the most common causes for AC failure.   Number 1 on the list is loss of freon.  Rubber hoses, seals, and valves are all common areas where freon will escape.  Occasionally the condenser on the front of the vehicle will pick up a rock. The seams on the evaporator inside the dash will bust from constant expansion and contraction.  There can be dozens of different o-rings and seals that may fail.   The biggest problem we see with freon leaks typically happen when freon is added to the system without a charge of oil.  When freon leaks out of the system, so will the oil that lubricates the AC compressor.  Once the oil in ... read more

Why it’s important to tell your mechanic/technician about work recently done to your vehicle

When you stick with one mechanic it will save you time and money due to the fact that they are familiar with your vehicle and past work performed.  If you decide to switch mechanics it could you save you tons of money if you communicate everything that any previous technician has done. The main reasons to disclose all previous repair work are: To aid in diagnosis Possibility for cause of current problem Improper installation Generalize area of concern To prevent redundant repairs Possibility of misdiagnosis Saves time and money   When an automotive technician is attempting to diagnose a customer’s concern, they methodically sort through the system that pertains to the concern. For example, if an A/C isn’t blowing cold air, the technician will check the components of the A/C system: compressor, A/C lines, sensors, freon level and pressures, electrical connections and components, etc.  The difficulty, in some cases, is when an unrelated system ... read more

Why do so many mechanics recommend work on my car? It seems to be running just fine.

Why do so many mechanics recommend work on my car? It seems to be running just fine.

Numerous studies have been performed on this subject.  One such study claims when a vehicle has regular maintenance performed it will save you $0.10 per mile driven.  That adds up to $300 dollars in savings between oil changes when you change your oil every 3000 miles.  Why is this you ask?  $300 for a transmission flush for a vehicle with these new super expensive fully synthetic transmission fluids seems like a ton of money.  When you compare that $300 for a transmission flush to keep the transmission like new to $3000 for a new transmission it doesn’t look so bad though.  The same goes for oil changes.  If you calculate $40 for an oil change you can get about 130 oil changes for the price of 1 engine.     Another reason for the lower cost is the increase in gas mileage on a properly maintained vehicle.  We performed an experiment in house recently where we changed the oil in an 06 Prius every 10,000 miles for a ... read more

My tires are wearing out quickly and unevenly. What is the problem?

My tires are wearing out quickly and unevenly. What is the problem?

The main reason for uneven tire wear or quickly worn tires is alignment.  As suspension components wear out over time and mileage, the slack caused will change the angles of the tires.  This effectively causes the tire to drag across the road rather than roll straight forward.  As the suspension continues to wear the vehicle will become unsafe to drive due to the inability to control the direction of travel.  In extreme cases a component such as a ball joint or tie rod end will separate and the wheel may fall off the vehicle. The solution to the problem of uneven tire wear and vehicle drifting is to check for play in the suspension ball joints, tie rod ends, bushings, shocks, and replace these components as necessary. Only then can the vehicle be aligned properly.  Tire balance also plays a small role in tire wear. #alignment #tire #wear #uneven #ball joint #tie rod

Why is my check engine light on?

Why is my check engine light on?

Have you ever had somebody tell you “don’t worry about that light”?  I am here to tell you they are wrong.  The check engine light is also known as a malfunction indicator light (MIL for short), and it means the engine computer has seen a fault in your vehicle systems.  There are literally thousands of reasons a check engine light will come on.  Yes, some malfunctions are more detrimental than others but they are all important for a safe, reliable, and efficient running engine.  Another misconception about check engine lights is that the engine computer will tell you what is wrong with the vehicle.  It only tells the mechanic that a malfunction has occurred in a specific system.  An example would be a P0401 EGR system insufficient flow malfunction.  This code could be caused by a faulty EGR valve, a clogged EGR passage, and/or a failed sensor. The moral of the story is that amputation before diagnosis only leads to malpra ... read more
