SOURCE: 2006 GMC Sierra Denali,wont turn over, battery

iF YOU HAVE NO 'CLICKING' OR ANYTHING THAT INDICATES A DEAD BATTERY - NO DASH LIGHTS ETC, THEN LOOK AT YOUR BATTERY FIRST, TRY TO JUMP IT. THISE ARE TOUGH TO JUMO AND TAKE ALOT OF JUICE TO START YOUR VOLT METER NEEDS TO READ OVER 13 VOLTS, DO NOT CONNECT TO BATTERY FOR BEST RESULTS, CONNET TO ENGINE, NEXT TO THE ALTERNATOR IS A GREAT SPOT, AND THE RED BLOCK THAT IS UNDER THE MASTER BRAKE CYCLINDER (YOU'LL SEE IT WHEN YOUR STANDING AT THE FRONT OF THE TRUCK AND LOOK TO THE RIGHT BETWEEN THE BATTERY AND THE ENGINE)

IF YOU CAN GET ANY JUICE TO THE CAR TO EVEN MAKE THE LIGHTS COME ON AND GET THE INSTUMENTS TO READ OUT, ETC BY USING JUMPER CABLES, THEN MAKE SURE YOU CAN GET JUICE, ALSO MAKE SURE THAT EVERYTHING IS OFF, ROLL DOWN THE DRIVERS WINDOW - OF COURSE YOULL NEED TO MAKE SURE THAT IF THE VEHICLE DOESNT START TO LEAVE THE JUMPER CABLES ON LONG ENOUGHT TO PUT IT BACK UP, AND CLOSE THE DOOR, LEAVING ANY ACCESORIES ON LIKE THE AC, RADIO, ETC JUST MAKES JUMPING THIS 10x HARDER, YOU MIGHT EVEN NEED 2 CARS AND 2 JUMPER CABLE, I THINK THE BEAST NEEDS SOMETHING LIKE 400 AMP TO CRANK OVER, IT'S ON THE BATTERY. ANYWAYS THE REASON WHY YOUR PUTTING THE WINDOW DOWN IS SO YOU DONT LEAVE THE DOOR OPEN AND WASTE JUICE, LEAVE THE KEY IN, BUT JUST PUL IT OUT ENOUGH SO IT'S NOT CHIMING. HAVE THE PERSON WHO IS JUMPING YOU SLOWLY REV THERE ENGINE TO SEND MORE JUCIE TO YOU. I HAVE THE SAME TRUCK AND HAD THIS HAPPENA MILLION TIMES. I FINALLY BOUGHT A JUMPER BOX FOR $50 AND IT SAVED ME ALOT OF HEADACHES. MY PROBLEM WAS I HAD A PROBLEM IN THE ELECTRICAL THAT LEFT A DRAW OPEN - THE IDEA THAT WAS POSTED ABOUT BYPASSING RIGHT TO THE STARTER IS A GREAT ONE, BU IF YOU NOT SURE WHAT YOUR DOING IT'S NOT REALLY THE 1ST AVE I WOULD TAKE, IT WILL JUMP THE TRUCK AND TURN IT OVER (UNLESS THERE IS ANOTHER PROBLEM) BUT WHAT ABOUT THE NEXT TIME? IF YOU PUT THE KEY IN AND GET A READING OF 13 +/- VOLTS ON THE DASH GAUGE THEN YOUR PROBLEM IS MOST LIKELY YOUR SOLINOID (SP) IT'S ABOUT A $60 PART AND EASY TO PUT IN, INVEST THE $$ TO BUY A CHILTONS OF EVEN BETTER A GM SERVICE MANUAL FOR THE TRUCK. WHEN YOU DO GET IT STARTED THE GAUGE SHOULD START TO RISE AND READ 14.5 +/- VOLT CONSISTANTLY, BUT IF YOU GO TO AUTO ZONE THEY WILL 'LOAD TEST' YOUR TRUCK FOR FREE. IF YOU STILL HAVE THE ORIGINAL BATTERY ITS TIME FOR A NEW ONE - AND DONT CHEAP OUT ON THE CHEAPEST ONE, SPEND THE MONEY FOR A GOOD BRAND OF BATTERY, SOMETHING THAT CAN HANDLE THE BEAST, 600 COLD CRANKING AMOS IS WHAT I THINK THE RATING FROM GM IS. IT WILL SAVE YOU A LOT IN THE LONG RUN. AUTO ZONE WILL HOOK UP A TESTER AND LET YOU KNOW IF YOUR BATTERY IS NO GOOD OR YOUR ALT IS BAD, ETC. BUT IT PRETTY MUCH ALLL STARTS WITH THE BATTERY.

THE ONLY OTHER THING IS THAT YOUR VEHICLE MAY BE IN LOCK DOWN IF YOU HAVE A KEY THAT IS WORN REALLY BAD AND ALOT OF MILES YOU MAY NEED TO REPLACE THE IGNITION CYCLINDER - ANOTHER $60.00 FROM THE PARTS COUNTER, AND THEN YOU NEED TO HAVE A BLACKSMITH CODE THE CYCLINDER, $35.00. HOPE I'VE HELPED

SOURCE: My gas gausge doesnt work in my 89 gmc sierra. How

If all your other gauges work, more than likely you have a bad sending unit in the gas tank or bad ground to the sending unit.

SOURCE: 2006 gmc sierra, the ac gets cold but doesnt blow

HI there. I am pretty sure that there is no correlation between the a/c not blowing and the emissions light. Does that air only not blow when the a/c is on or does it not blow when the heater is on as well. A main reason that would cause the air to not blow for the a/c is if the fan is not working. A blown fuse, blown relay, bad wiring and mechanical defects in the blower unit would cause failure. As for the emissions light there are litterally dozens of things that would turn that on ranging from bad O2 sensors to clogged EGR. Take the car to an auto parts store light NAPA or Car Quest to have the trouble codes read for free.

Where do i find the horn fuse box on a gmc sierra a 2002


There isn't a fuse. Just a relay. Either the relay is dead ( not likely) the horn is dead ( most likely cause) Or the steering electrics is bad. ( most likely on this is the plastic piece inside the steering wheel has broke)

Horn on 2002 Gmc Sierra 1500 stopped working. Horn stated boleing fuses a couple of years ago and was just changing fuses to fix problem short term. Last time horn stopped working I changed fuse and it did...


Sounds like the horn itself is shorted out. You didn't mention if the blown fuses were a result of using the horn. A horn in construction is an electromagnet acting on a diaphram; if the electromagnet develops a short, it causes an overcurrent condition and will blow the fuse.

There is a relay for it. Pin# 30 is power and pin # 87 goes to the horn, and pin #85 is power and pin #86 comes from the steering column.

Horn doesn't work on 2005 Pontiac Vibe. Can't


On the 06 Vibe the horn is located just to the right of center, almost below the hood latch, in front of the radiator. It looks like a small round speaker...
check to make sure the wire is plugged in, it can come lose or even fall out. it is easy to check and fix.

If that does not work, my best guess would be that either the horn is blown or the wiring is messed up.

good luck.
