Holden Nova Pricing and Specs

The most common way to do this is to lower the window completely via the button, and hold the button down for an extra five seconds. Then, close the window fully with the up button, and hold that for another five seconds. Usually, this will reset the windows so that the body computer knowns where they are and can operate the automatic up and down functions correctly.

In some cars, you can achieve the same by standing next to the car and holding the locking button down on the key fob for 30 seconds. If that doesn’t work, try the unlock button for the same 30 seconds.

You were on a pretty good bet that the problem was a case of warped brake rotors, but it seems new rotors have not fixed the problem. In which case, you need to start looking deeper into the suspension and front end of the car. There could be a worn bush or ball-joint, or perhaps something in the steering needs tightening or replacing. A slightly bent stub axle could also cause this. Make a note of whether it happens in corners (left or right) under light or heavy braking or even when accelerating. This information will help a mechanic diagnose the problem accurately.

But don’t ignore this as the problem will only get worse as whatever is worn becomes more worn. Eventually, you’ll have a car that shudders all the time and is unsafe to drive.

Many engines lose rpm when they are sitting at a hot idle. The problem could be with the fuel or ignition systems, but could also be a stepper motor that either needs to be replaced or reset (to re-establish the correct idle speed).

The oil light will be flickering because the sensor is telling the computer that there’s not enough oil pressure being generated to lubricate the engine properly. In turn, that’s because hot oil is thinner than thick oil (which means less oil pressure) and the amount of oil pressure generated is directly linked to how fast the engine is running. Hot (thin) oil plus a slow idle, means a dangerous fall in oil pressure.

If the oil pressure light goes out when you rev the engine a little, it will probably be okay, but don’t drive it like that for too long. Once the idle speed is reset, the oil light should not flicker on again. If it does, change the engine oil to a thicker (higher viscosity) specification.
