Hello,
96 Cavalier LS 4-dr sedan, 2.2L automatic.
Daytime Running Lights do not work, there is a symbol that looks like a little headlight that constantly flashes when the DRL should be on. I checked the headlight bulbs (all good), and the low and high beams work normally. I also replaced a relay in front of the radiator that controls the DRL, no help. Not sure what else to check for, any help appreciated. I have a repair manual that shows a wiring diagram, with something called a BCM (body control module) producing a signal to activate the DRL, yet someone told me this year Cavalier does not have one?
Do you

Thanks, but I cannot read this picture, it is too tiny... Do I have to pay to see the full size one?

Maybe this will help a little-if not comeback I'll get someone that knows computer magic

I found (using the wiring diagram) that there was an open wire for the DRL signal from the instrument panel down to the relay. Rather than mess with trying to find the problem (it was not at the two connectors), I ran a separate wire, splicing it into the connectors (after cutting the original wires about an inch from each connectors). Problem solved.
