Chrysler Pt Cruiser Headlight

How to Troubleshoot Chrysler Common PT Cruiser Headlight Problems

Because they provide visibility to the driver and make the vehicle visible on the road under low-light conditions, a busted Chrysler PT Cruiser headlight is not something to be scoffed at. The PT Cruiser's headlights can fail due to a variety of reasons, and knowing these different causes are can help you save money on repair and replacement costs. In this guide, we'll list some of the headlight problems of the Chrysler PT Cruiser and how to troubleshoot them.

The headlights don't light up

If one or both of the headlights of the PT Cruiser don't work, it could be due to one of several reasons. If only one of headlights isn't working, the problem could be simply a burned out headlight bulb. But if both headlights aren't working, it could be due to a malfunctioning headlight relay, module, headlight switch, dimmer switch, a busted fuse box or a fault in one of the headlight's electrical wires. On the other hand, if your PT Cruiser is fitted with an aftermarket Xenon headlight, the failure maybe caused by a bad ignitor or ground connection or a wiring harness fault.

The brightness fluctuates

On the other hand, if the headlights do light up but fluctuate whenever the gas pedal is pressed, there may be a problem with your car's alternator or that the alternator drive belt is slipping. Using a voltmeter, check the voltage of the battery with the engine idling. Ideally, the voltmeter should display 13.5 to 14.5 volts; anything less than that indicates a problem with the alternator.

The headlights don't light up the road very well

Check the headlights for dirt or fog. Dirt on the outside of the headlights or moisture inside the headlight lens cover can reflect the light back, thereby reducing its brilliance. In older PT Cruiser models, constant exposure to UV rays from can cause the headlight lens to turn into a dull, milky white color and must be polished in order to restore its brilliance. In addition, newly installed or modified headlights may also lose its alignment, causing the beam to be aimed too high, too low, or off center.

  • 3 Simple Maintenance Tips for Chrysler PT Cruiser Headlights 27 February 2013

    One of the key steps to a safe night-time drive in your Chrysler PT Cruiser is to regularly maintain its headlights. While they are made from durable, high-quality materials, Chrysler PT Cruiser headlights will eventually succumb to everyday wear and tear without proper maintenance. What's more, caring for the headlights is quite easy, and only takes several hours to accomplish.


    Clean the headlights regularly

    Dirt on the surface of the headlight lens cover can cause the light to reflect back into the housing and reduce the beam's effectiveness. You can use ordinary car shampoo to wash the lens cover, although we recommend using toothpaste as the chemicals it contains to whiten teeth can also clear up the yellowish haze on the lens surface. Make sure to use only regular toothpaste, however, as whitening toothpaste usually contain extra compounds which can damage the headlights. We also recommend buffing the lens cover afterwards with clear polish for an even shinier look.


    Remove foggy haze on the lens cover with sandpaper or mild abrasive polishing cream

    Over time, exposure to the UV rays of the sun will cause the plastic lens cover of the headlight to deteriorate, resulting in a milky-white foggy appearance. This haze can usually be removed by rubbing it with mild abrasive polishing cream or fine grit sandpaper, but in case of severe deterioration it's better to replace the headlight housing instead.


    Check for and remove condensation from inside the lens

    Due to differences in temperature inside and outside the headlight housing, moisture may start to develop in the form of tiny droplets on the interior side of the headlight lens cover. This is particularly frequent in older PT Cruisers, as the gaskets that seal the headlight housing to its lens cover may have worn out and allowed moisture to enter. In most cases the condensation evaporates once the headlights heat up, but if it remains it can reduce the headlight beam to reflect erratically, reducing its effectiveness. In addition, long-term exposure to moisture may also cause the socket of the headlight to rust and malfunction. To remove excessive condensation, you can either disassemble the housing and wipe it dry, or, if you don't mind tampering with the headlight a bit, drill a tiny hole on the top of the housing and allow it to dry in the sun.
