No power when accelerating
have a load test done on the battery to check for dying cells . have a output test done on the alternator to check for correct operation. check condition and tension of drive belt for the alternator
Rear windshield fluid not working on gmc yukon
Could be a block near or at fluid bottle at the splitter valve. Try unplugging pipe at nozzle and blowing back through. Check inside nozzle too. Lots of gunk can settle at base of bottle.
2004 GMC Sierra Computer reset ??
I would suggest stopping by an AutoZOne or O'Reilly's and "borrow" their Scan Tool to erase any codes.
TO reset the "Change Oil" light, turn the ignition to ON (do NOT start the car). Press the accelerator pedal all the way down (then release) to the floor 3 times in less than 5 seconds. Change Oil light should flash then go off. If not, try it again. The trick is to get this done in 5 seconds ro less.
2007 yukon denali, when the incorrect sequence is
This is not a normal condition. Unlocking the car a starting it with the key should reset everything. Contact your local GMC dealer about getting this repaired. Unless you are a high-miler, you should still be under the factory warranty.
I own a gmc denali yuxon xl and i have just been
how many filters are they replacing
if its just intake filter id say they would charge 50 for filter and 50 for service
you can change those filters very easily your self if you wanna save some money try you tube and find a video on how to

Change head light
You should be able to reach under the hood into the headlight assembly and grab the bulbs and twist them off if not then you have to take off your entire headlight assembly then take the bulbs out.

Finding kill switch in 2004 gmc denali car will not start
There is no factory kill switch.
You need to explain your complaint ... Guessing at the reason will not help here.
If the engine spins around with the key but will not start then you have a crank no start. If you kick the bottom of the gas tank whild someone is turning the key to the start position and it starts then you need a fuel pump. Very common and about a $500 job on the low end.
I have a 2008 GMC Yukon XL Denali. I hit a small snow drift yesterday and now my speedometer stopped working, my RPMS are bouncing, oil pressure is bouncing, temp is bouncing and vehicle wont shift o
Taking the vehicle to a qualified repair shop an having a full scan of all the control module's on the vehicle should be the first step in the diagnostic procedure , All the instrument cluster gauge function's start in the PCM - engine computer . Sent to the instrument cluster over the GMLAN serial data network .
Without testing we'd only be guessing . Probably has a U code stored in one of the module's pointing to a cause . Could be just a loose connection . Checking wiring harness connection's . Circuit Description
The communication among control modules is performed through the high speed GMLAN serial data bus, the low speed GMLAN serial data bus, and with RPO HP2 the high speed hybrid GMLAN serial data bus. The modules that need real time communication are attached to the high speed GMLAN busses. There are several modules that act as the gateway module or translator for communication between the various serial data busses. With RPO HP2 the serial data gateway module (SDGM) is the gateway and on all others the body control module (BCM). All high speed modules are activated by a communication enable or wakeup circuit from another module as determined by the power mode master (PMM).
Refer to Data Communication Schematics to determine the circuit and module that activates specific high speed modules.
Signal supervision is the process of determining whether an expected signal is being received or not. Some messages are sent on a periodic basis and are interpreted as a heartbeat of a device. If such a signal is lost, the signal supervision part of the software will set a no communication DTC (U. code) against the missing device. This code is mapped on the Tech 2 screen as a code against the physical device. A lost communication DTC typically is set in modules other than the module with a communication failure.
Speedometer
The IPC displays the vehicle speed as determined by the ECM. The IPC calculates the mileage based on the serial data vehicle speed information from the ECM. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of serial data communications with the ECM.
Tachometer
The IPC displays the engine speed as determined by the ECM. The IPC receives a serial data message from the ECM indicating the engine speed. The tachometer will default to 0 RPM if:
• The ECM detects a malfunction in the engine speed sensor circuit.
• The IPC detects a loss of serial data communications with the ECM.

Hi the last digit is 0 this means its detected a fault but it does not know why the misfire is if it had 1 at end it would be sparkplug 1. and so on. 0 could mean there is a problem with the timing or there is something wrong with the coil pack , coil pack it could be a fault at the plugs or the wiring. if you remove the spark plugs and the one or 2 that don't look right, investigate them, make sure there is no problems with the case of the coil pack. color of the connections and the case cover no cracks or splits. it can also be blocked jets this can limit the fuel into the engine and cause the same fault.
