why do my 2004 caravan headlights keep blowing
Check the alternator output voltage around 2000 RPM, it should be no higher than14.2 volts. Also check the connectors and grounds for both headlights, make sure they are corrosion free, after the wiring is checked and repaired if needed check the voltage at the headlight connections, it should not be any lower than battery voltage, if it is then you will have to trace out the headlight power pathways.
