Audi Electrical Diagnosis – HVAC Blower Motor and Control Module Failure

Awww Audi Mike our shop foreman at the Atlantic Technical Center (ATC) discovered this today when diagnosing a HVAC fault in a client car. Nice call Mike! Now this is bad...whenever we find melted connectors, it's what we call a "clue", but also is a very interesting find, instructive even. Especially if you understand Ohm’s Law or E = IR, and also the relationship between heat and resistance, also known as P=I2R. Great question! Normally electric power is useful, making a lamp light or a motor turn for example. However, electrical energy is converted to heat whenever a current flows through a resistance and [...]

Mini Cooper Clutch – When Good Flywheels And Pressure Plates Go Bad

Background Let's talk Minis! As there is no Mini Cooper new car dealer in Maine, we've become the largest Mini service center in the state, aside from the routine day-to-day service, we also get to see some interesting Mini Cooper service challenges, like this one. 'Da Clutch Mini Coopers are wonderful cars, but like all cars, clutches do wear out with use and milage. What we’ve also seen is problems with excessive clutch pedal effort. The problem comes on rather slowly, is often not noticed by the driver, who becomes acclimated to it as he/she is using the clutch every day. [...]

An Ounce Of Prevention – Antifreeze and Coolant Service

The Importance Of Antifreeze/Coolant Service Take a look at these photos, notice the brown areas of clogging and material at the bottom of the radiator? Nowhere is this more frequent than on engines using an aluminum cylinder head, and cast iron block…like most modern cars. And we also find this clogging not just in radiators, but also in heater cores. A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core. Fins attached to the core tubes serve to increase surface for heat transfer [...]

Car Batteries – Facts About Lead Acid Or AGM Types

BMW and Mercedes Benz – Ceramic and Aluminum Fuse Problems – How and Why

About The Problem One of the more common electrical issues we see with the vintage Mercedes vehicles are problems related to the fuses and fuse box. Like many of the older European models, these cars were designed and engineered with identical or similar parts, in this case, the ceramic and aluminum exposed fuses. At the time, this was an excellent solution, but now, some 20 years later, we frequently see a series of pattern failures on vintage Mercedes, and almost always the same issue over time: fuse failure. While the ceramic and aluminum fuse failure is particular to older European vehicles; however, it’s a simple problem to fix in [...]
