IS THERE A CONNECTION OF HAVING THE RADIATOR FLUSHED AND A NEW THERMOSTAT INSTALLED, CAUSE THE PANEL LIGHTS TO STAY ON? THIS WAS RECENTLY DONE AND I NOTICED THE PANEL LIGHTS STAYING ON, THUS RUNNING DOWN A 1 YEAR OLD BATTERY NEEDING A JUMP START 2 CONSECUTIVE MONDAY MORNINGS . THE BATTERY WAS TESTED AND ALL SHOWED NO PROBLEM WITH IT. SOUNDS FOOLISH, BUT NOTHING ELSE WAS DONE TO THE CAR THAT I KNOW OF.. I NOW RUN THE CAR AT LEAST 20 MINUTES PER DAY AND THE CAR WILL START IN THE MORNING.
My car has 81000 miles.
My car has an automatic transmission.
Normally, touching the thermostat or radiator would have no relation to lighting. I cannot say if something like a ground wire may have been disturbed while working on the vehicle from a distance. generally, even a new or good battery can be drained if there is a constant power draw or short. Noticing that the panel lights are staying on, can indicate the problem is in that circuit. It can be a loose ground, a chaffed or damaged wire that is making contact with bare metal somewhere, completing the circuit and acting as sort of a switch by itself, and keeping the lights on. The light switch itself can be shorted internally.
A certified technician can diagnose the battery drain and isolate the exact cause.
