Default Re: question about daytime running lights

Did you check for blown fuses? (several shown in the diagram) Is the DRL light on when driving during the day?

Here's a link to wiring diagrams and pdf: http://www.saturnfans.com/forums/sho...d.php?t=160679, post#5. Below is the same wiring diagram stitched together into one drawing.

The wrench light indicates error codes unrelated to emissions. Better readers capable of reading/displaying wrench codes are a step up from generic readers. According to the diagram, the instrument panel has the chip to determine choosing DRLs or not, turning on the DRL light when in drl mode.
