Your trusty steed has carried you reliably through the dark winter months. Now's the time to repay that loyalty, and garner some more, by getting started on those maintenance jobs that help your car or truck make it safely through warmer weather. Don't wait until you're sweating, get going now and by the time summer hits you'll be more than ready!
Many modern vehicles use solid state relays instead of the electro-mechanical ones of the past. The fans they control draw a huge amount of current and the connectors which plug into the solid state felays to power these high current fans fail over time. The connectors get to HOT the pins melt which causes high resistance and finally an open circuit and the fan shuts down. This is so common the dealerships actually sell the connectors to be spliced onto the wiring harness with butt connectors without having to replace the entire harness. This is almost unheard of except that it has become so common the manufacturers had to do something about it. If you have an electric fan problem be SURE to pull off the connector going to the solid state relay and look INSIDE of the connector and smell it(the inside). It will smell burnt and look like charcoal if it is bad. You can't tell by looking at the outside surface. You MUST pull it OFF and look and smell on the INSIDE.Having a community of repair people sharing their experience means no stone goes unturned in diagnosing your car or truck's problems. Thanks for the tip, Allan!
