When a customer meets the limitations of electrodynamics
More than a decade ago, a customer brought his late-1990s Suzuki Sidekick into our shop and asked us to install a 2,000-watt power inverter that he had purchased. His goal was to have 120-volt household power available while using the vehicle.
Engine Cooling Fan Low Speed Problem? Check the Resistor
In an effort to improve fuel economy, and reduce unnecessary engine load, mechanical engine-driven cooling fans have largely given way to electric cooling fans. Depending on the application, these systems may use high and low speed relays or a PCM-controlled pulse-width modulated (PWM) signal sent to a fan control module.

Transit has passive aggressive back-seat driver
TRENDING TSB
There are some noises you never want to hear coming from the rear of your vehicle. For owners of certain 2015-2022 Ford Transit vans, a mysterious moan at highway speeds is apparently one of them. According to Ford Technical Service Bulletin 22-2271, certain rear-wheel-drive, single-rear-wheel Transit models may produce a boom, hum, or moan from the rear between 70 and 90 mph, depending on axle ratio. Ford says the culprit may be a second-order driveline frequency traveling through the rear driveshaft and axle and into the body through the leaf springs.
