My 01 ls headlamps are always on when they are set to auto. They
turn of when the key is removed and the prescribed time has passed as
set by the dial as they should but for some reason don't sense its day
light. Any ideas, maybe just a bad sensor on the dash?
No my dash lights dim during the day when switched to auto as the
headlamps come on as if it were night, so you cant see the interior
dash, radio etc. When I manually switch the headlamps off the interior
dash/radio brightens as it used to. This car does not have DDRL. Some
thing is broken and I am wondering if someone else had a similar
problem and a solution.
Double-check where the sensor is to make certain nothing is obviously
blocking it, or it's not just dirty.
I had a similar issue with my 2000 Sable. It was just the connector to
the sensor had worked loose. It also affected the automatic climate
control, because it also uses that sensor as a sun load sensor. There
was a procedure in the manual to run a test on the climate control to
check the sensor, which failed.
