Troubleshooting tips for a Buick include how to deal with intermittent starting, power window malfunctions and unexpected engine stoppage. Tips for fixing a separated dashboard, as well as handling a fuel level sensor failure, are also available.
Intermittent starting could be the cause of worn spark plugs or simply a bad ignition. With Buicks, starting problems increase when the engine is hot. This level of heat is caused by a malfunctioning fuel pump or fuel pressure regulator. Take the Buick to a professional mechanic for diagnostic tests to determine which is at fault.
Power window malfunctions are common in Buicks. They can impact the function of one window or all the windows and can vary in extremity from rolling up and down slowly to not moving at all. This could be the fault of the window regulator, but if it is in tact, the window motor may need replaced. While replacing it requires removing the door panel, it is an easy and inexpensive fix.
Unexpected engine stoppage could indicate a major problem with a Buick's computer; it may need to be replaced altogether. However, often the installation of a new oxygen sensor solves the problem for far less money. Take the vehicle to a trusted mechanic for diagnostic tests to determine the root of the problem.
Separated dashboards may seem like little more than an inconvenience, but it can impact the deployment ability of air bags if an accident occurs. To fix minor separation, add screws to connect the dash. For major separation, the dashboard may need completely replaced.
Fuel level sensor failure occurs when the gas gauge does not correctly sense how much gas is in the tank. The sensor likely needs replaced, but it is expensive; many owners opt to track their mileage and estimate gas usage.
