Disabling DRL on a 1999 J-body Open the door on the fuse panel (the one inside the car). The door shows a map of the fuses and such. There is a relay that is marked DRL. Remove this Relay by simply pulling it out. Now the DRL's are disabled. Two side effects though. 1) the DRL light inside the cars blinks when the DRL's should be on. 2) High beam on the passenger side no longer work. side effect number one. not solved yet. side effect number two. Look at the DRL relay and find the prongs #30 and #87a. Now get a little jumper wire and put it where the two prongs are when the relay in inserted. This will fix the high beam problem.
