Power door locks are the most important security element of your vehicle. They keep potential thieves and burglars out of your car, and make it easy for you to lock and unlock your doors in a hurry. As a result, power door locks that don’t work are a little unnerving, as they spell an increased security threat for your vehicle. The power door lock system is a relatively simple system. When you press the lock or unlock button (located on your key, or inside your vehicle), the power door lock sends a relay signal to the power door lock actuator. The actuator, through a series of gears, locks or unlocks the door or doors that you are controlling. Power steering fluid is a necessary part of your vehicle’s power steering system. The fluid is pumped from the reservoir to the wheels by the power steering pump. Near the wheels the power steering fluid applies pressure to a piston inside the rack and pinion, which is connected to the wheels. This pressure gives the wheels the strength needed to turn and makes a vehicle dramatically easier to steer. When the fluid becomes contaminated, the entire power steering system can be damaged. The dark colored power steering fluid can clog the power steering pump hoses and damage the bearings in the system.

A mechanic can often tell by the sound whether the problem lies with the fuse, the power door lock switch, or the power door lock actuator. After determining the problem with the system, the malfunctioning piece will be replaced. In rare instances a broken power lock actuator can be repaired, but usually any part of this system will need to be replaced if it isn’t working properly. Discolored power steering fluid cannot be reversed. Instead, the fluid needs to be drained from the power steering system and replaced with fresh fluid. This is called a power steering fluid flush. A mechanic will disconnect the power steering hose from the power steering pump and drain all of the fluid out of the system. After reconnecting the hose to the pump, a fresh batch of clean power steering fluid will be added to the reservoir. Once the system has been flushed, the mechanic will usually turn on your vehicle and turn the steering wheel a few times to introduce the new fluid to the system. This process will also allow your mechanic to identify any other issue that may require his or her attention.
