#378 of 472 Re: daytime running lights turn off when I put on turn signal [tiffs26] by tiffs26 Mar 11, 2009 (7:06 am)
Replying to: tiffs26 (Mar 10, 2009 7:50 pm) I talked to a GMC dealership and they said the DRL are supposed to turn off when the turn signal is on. So if anyone has any question, there's your answer.
#379 of 472 Daytime running lights going off when signal is used by cardoc50 Mar 11, 2009 (7:34 am)
THE RUNNING LAMPS ONLY GO OFF WHEN THE ENGINE IS TURNED OFF. THEY ARE SUPPOSED TO STAY ON AS LONG AS THE CAR IS RUNNING. IF YOU PUT ON THE EMERGENCY BRAKE, THEY WILL TURN OFF. I OFTEN PUSH MY E-BRAKE ONE CLICK TO TURN THEM OFF WHILE DRIVING. BELIEVE IT OR NOT, THE MULTI-FUNCTION SWITCH PROBABLY NEEDS REPLACED. I HAD NO BRAKE LIGHTS,OR SIGNALS. A LOT OF STRANGE THINGS HAPPEN WHEN THIS SWITCH GOES BAD. ALMOST ALWAYS TO DO WITH SOMETHING WITH REAR LIGHTS. CHECK THE SWITCH. THEY COST ABOUT $300.00. I FOUND NEW ONES ONLINE AND PAID ONLY$32.00.GOOD LUCK! Replies to this message: tiffs26 (Mar 11, 2009 9:38 am)

Replying to: cardoc50 (Mar 11, 2009 7:34 am) Like I said in my earlier statement, I talked to the service department at a GM dealer, and he said they should turn off when the blinkers are on. I think I'm gonna take his word for it.

Replying to: piper5 (Oct 25, 2006 5:21 am) You may want to check the recall site. There was a recall on some part of the brake that would cause the brake to flip over.

Replying to: diy2 (Jun 19, 2009 10:45 pm) ON MY JIMMY,FUSE#15 IS DRL/FOG. WHICH MEANS DAYTIME RUNNING LIGHTS OR FOG LAMPS WHICHEVER YOU HAVE. TO DETERMINE IF THE SHORT IS IN THE DRL, PUSH THE PARK BRAKE IN A COUPLE OR MORE CLICKS THEN SEE WHAT HAPPENS. THE DRL'S SHOULD NOT BURN WHEN VEHICLE IS STARTED. IF THE FUSE BLOWS THERE A COUPLE THINGS IT COULD BE. YOU BOUGHT THIS VEHICLE USED.WE DON'T KNOW WHAT WAS DONE TO IT EARLIER.CHECK THE REAR OF YOUR HEADLAMPS TO SEE IF ANYONE HAS TAMPERED WITH THE WIRING. IF YOU HAVE FOG LAMPS, UNPLUG THEM AND SEE WHAT HAPPENS.IT'SLIKELY THAT ONE OF THESE TWO MAY BE THE BROBLEM..IF NOT, TRY CONTACTING ME AGAIN AND I WILL GIVE YOU SOME INFO ABOUT ELECTRICAL PRBLEMS AND RE-CALLS, AND ALSO TSB'S THAT ONLY GM GETS. I CAN SHOW YOU WHERE TO GO ONLINE TO GET THEM.IF MORE PEOPLE WOULD COMPLAIN ABOUT ELECTRIC PROBLEMS ODI WILL MAKE THEM HAVE A RECALL ON THIS TOO I HOPE THIS HELPS.

Replying to: cardoc50 (Jun 20, 2009 8:03 am) Thanks for prompt respond.   I must admit I jumped to the conclusion, thinking that all the fuse boxes are the same. On my 2000 Jimmy, the Fuse# 15 is 4wd (???). In the manual it's described as:   "4WD Switch, Engine Controls (VCM, PCM, Transmission)."   You are absolutely right when you say I have no idea what has been done to the vehicle. One thing that is noticeable is stereo. But how much that can affect 4wd. Got my self Chilton, thou seams there's every important wiring diagram Except the one for 4WD????   Last time I put the fuse in, and left it idle w/o shifting into a gear, the fuse didn't blow. When I came back to it that night, put it in reverse and drove outta garage the fuse blew. Which makes me think that could be nothing happens "until" you shift and/or into a Reverse?   I was just about to start unpluggin' things tomorrow. Just not sure where to start. If I would only be able to isolate the thing that would be fantastic...   thanks again,... greatly appreciated Replies to this message: cardoc50 (Jun 21, 2009 4:10 am)

Replying to: diy2 (Jun 20, 2009 11:14 pm) OK. THIS APPEARS TO BE A VACUME LEAK. THE 4WD SWITCH IS OPERATED BY ENGINE VACUME. IF THERE'S NOT ENOUGH VACUME IT WON'T CHANGE INTO OR OUT OF 4WD. FIRST THING TO DO IS FIND THAT LEAK. SOMEONE MAY HAVE HAD THE TRANNY OUT AND PINCHED OR BROKE THE LINE. YOU MAY HAVE A SIMPLE LEAK IN THE ENGINE COMPARTMENT. CHECK THERE FIRST. YOU CAN USE STARTING FLUID OR SOMETHING LIKE SOAPY WATER IF IT'S RELATED TO THE INTAKE PLENIM OR MANIFOLD. SHIFTING INTO REVERSE MAKES THE FUSE BLOW YOUMAY HAVE A GROUND IN THE REVERSE SWITCH OR THE WIRING THEREOF. HAS ANYONE PUT AFTERMARKET BULBS IN THERE? YOU KNOW THE KIND PEOPLE USE WHEN TOWING SOMETHING? HAS THE VEHICLE BEEN IN AN ACCIDENT? SOMETIMES A BODYSHOP ACCIDENTLY WILL SMASH A WIRE IN THE PEOCESS OF REPAIR. IT LOOKS TTO ME THAT YOU ARE GOING TO HAVE TO USE THE PROSESSE OF ELIMINATION IE... TAKE CARE AND TRY ON THING AT A TIME TO RULE OUT DIFFERENT POSSIBILATIES. USE A STETHOSCOPE TO FIND VACUE LEAK ALSO.I WOULD ALMOST BET THOUGH THAT YOU HAVE A GROUND IN THE WIRING AT THE TRANNY OR TRANSFER CASE. I HOPE YOU CAN FIND IT AND IF IT IS A RESULT OF A REPAIR, FIND OUT WHERE IT WAS REPAIRED AND SEE IF THEY WILL ASSIST YOU. SORRY I CAN'T PINPOINT THE PROBLEM WITHOUT SEEING THE VEHICLE.MAYBE SOMETHING I SAID WILL HELP. A VACUME LEAK WILL NOT BLOW A FUSE. GOOD LUCK
