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.
