2005 Chevrolet Impala. Simply pull the DRL relay out of the fuse block under the hood and bend over pin 87. Why this works: Pins 87 and 30 are the two pins that are connected together when the relay is energized. Bending 87 over will still let the relay energize but since the pin is bent over, the DRL's don't come on. As long as the computer senses the resistance of the relay coil between the two trigger pins (85 and 86) it thinks all is OK and doesn't set any codes. If you bend over either of the trigger pins like suggested for other vehicles, the computer will display "Service Vehicle Soon" in the info center.
