turn off drl 2003 s 10

WOW – In a world when we all need the mpgs, why are we still using DRL’s?  Well… I for one would like to turn off mine on this 2003 Chevrolet S-10 pick-up. With the best lubricants installed, the $8.00 each for spark plugs, and getting the fuel saving 2.2, 4 cyl. motor, I still can only get 21 mpg’s. (That is driving 65 mph in a posted interstates 75 mph limit)  I traded a 2002 cavalier with the same 2.2 that I was able to boost the mpgs up from 26 when I bought it used at 40,000 miles to 36 mpgs when I traded it with 78,000 miles on it.  While I have boosted the mpgs up from 17 when I bought this S-10 used with 60,000 miles to the weak…current 21 mpgs at 71,000 miles, turning off the drl is the next thing to do.

Check out lightsout.org.  They have instructions for various vehicles - I agree that DRLs are a major nuisance.

Unfortunately it's usually more involved than pulling a fuse or relay tedmond, that will tend to cause the "Service Vehicle" light to come on(which can't just be erased with an OBD-II scanner), and on headlight DRLs it may cause the low or high beams to not work, since many GM DRLs just use the relay to wire the headlight bulbs in series.
