GMC Questions and Answers
My 2006 Yukon Denali XL's battery has died twice in the last month. I had a 2004 that died at least 6 times in the 2 years that I owned it. Anyone else have this problem?
Is the battery old? It's possible the battery has become weak and this cold weather really drained it. Cold weather really does a number on batteries. Most shops can test the battery for you and many auto parts stores will test it for free if they have the tool. It's possible something else is draining the battery when the key is off but that would require some basic electrical knowledge and a multimeter to diagnose
my vehicle starts right up it dont over heat and has no loss of power but throwing out white smoke when driving or just idleing it blows out horrifcly could it be the head gasket or block
It's very likely that the head gasket is your problem. These gaskets often leak if the engine has been overheated, but can occur on an engine with high mileage too. The next step is to have a shop remove the head(s) and inspect the head gaskets.
im not getting enough fuel pressure any ideas
It sounds like you have a fuel pump that is failing. Your 96 Jimmy runs at about 60psi fuel pressure - anything less will cause a hard start or no start condition. If you have fuel pressure but it is low you will need to replace the fuel pump module assembly which is located inside the fuel tank.
my jimmy wont fire what could it be
The most common reason for your 96 Jimmy not to fire would be a faulty fuel pump. Fuel pressure should be about 60psi for your engine to start. If fuel pressure is OK the next step would be to check for spark and proper engine compression.
I have a 2005 Yukon Denali - the light behind the defrost button is out - how do I replace it.
The buttons for the front and rear defrost on your Yukon are part of the climate control panel. Is the defroster in question working OK? If so, the light only is at fault and you will need to replace the complete climate control panel assembly - you cannot replace just the light bulb. If the defroster is not working the system will need to be repaired, then you may see the light working again.
Have a 2002 Yukon SLT4WD. When I drive my car by night. The battery meter goes down everytime I brake or release the accelerator pedal and sometime it even turns off the car. I chekced the sparkplugs, the alternator, they're when I drive in D. The lights or the battery goes down. can you help me about it?? (I live in Tahiti
Thank You... William.)
It sounds like the engine idle may be to low on your Yukon. There could be deposits built up behind the throttle plate which will restrict the air flow at idle. The fix would be to clean the throttle body area with carburetor cleaner and wipe it out with a clean shop rag. There may also be a software update available from GM which will help the computer compensate to the build-up of future deposits in the throttle body. The check engine (SES) light may be on after cleaning the throttle body and the code set will need to be cleared to turn off the light.
I have a 04 envoy and want to know how it would sound if i cut the resonator off and ran straight pipe?
I want it to be a deep sound when i install the straight pipes out the back(is that to much to ask). I'm simply just cutting off the resonator and welding on straight pipes to get a deep NO POPPING OR CRACKING NOISE from it. Is this right is this how it works?
I would have the muffler shop install flowmaster exhaust on your 2004 envoy instead of cutting off your resonators, Plus it might not pass a smog test if you modify your stock exhaust.

check their ebay for a better deal

I'm convinced if you can't find what your looking for on ebay, the part may not exist. There are catalogs for after market parts as well in the ebay motors areas.
try the general motors website
Trying to help a friend w/ their 1990 GMC Jimmy. Someone did brakes for them 4 or 5 yrs ago, and seemed fine since then but about 1 yr ago ABS light came on. Brakes have been working fine and everything I checked seems fine, doesn't seem anything is wrong. Any idea why light is on, what else I can check? Or if nothing is wrong how can I get light off? Live in a state where vehicles have to pass inspection, and my friend is worried this will not pass with light on even though nothing seems to be acting up. Thanks!!
May just be a burnt out brake light bulb.
Have a mechanic check the brakes. General Motors has had a problem with the ABS light for a long time. I have a 2000 Chevy Blazer, and the same thing happened to me. There is a sensor of some kind that goes haywire. I had the brakes checked, and the pads and lines were O.K. Had the sensor changed, and the light went out. I think it cost about $55.00, but can't remember for sure.
I want to buy my friends its a 97 and has 96,000 on it, everything works... i have little money and hes cuttin me a deal...so are they decent cars? do they have any issues?
walk away from the deal. they have many issues, electrical, leaks, etc.
Not many good reviews on the link below.
My Mom had a '98 that she bought fairly new(2 years old and ~30,000).
The thing was an absolute maintenance nightmare-in the shop every other week with a different problem, it seemed like. A couple of times involved some pretty serious recalls, like one which involved a complete replacement of the entire cooling system.
Other than the maintenance nightmare, it was a decent car. It drove well, and looked nice. It was also comfortable to ride in, although admittedly not your typical Cadillac ride.
Personally, I would avoid one at all cost, especially a '97 model. The Catera is the reason why both of my parents now drive Lincolns.
EDIT:
"walk away from the deal. they have many issues, electrical, leaks, etc."
I'd forgotten about the leaks. Every time it rained, the passenger side carpet would get soaked. On a few occasions, there was water standing on the passenger side floor of the back seat. This was always after a long, but not particularly heavy, storm.
Even multiple trips to the dealer(fortunately all under warranty) didn't resolve it.

My 4wd Sonoma has been an excelent truck. The engine has a bit of a rough idle (from new) but runs strong and gets OK gas mileage. Front brakes wear out on the early side and now I have developed a noise in the front end, maybe worn control arm bushings. The only major repair has been a fuel pump replacement at 70k. |

Basically a safe vehicle but typical GM poor quality; door handle fell off, plastic interior parts broke easily, A/C compressor went out at 52,000 mi., door light spring switch fell off, right turn signal doesn't cancel, daytime running lamps no longer operational AND most importantly the BRAKE SYSTEM ANTILOCK SENSOR IS MALFUNCTIONING. Next time, go to Honda or Toyota |

good servicable pickup |

The smooth running V6 makes this SUV, and Lots of power. The ride is also good. Only a few minor problems. This truck just runs and runs. |

I had this Suburban for 10 years and it did not hold up well. I had to replace the transmission and the rear end when it had less than 100,000 miles. The air conditioning vents were falling off, the headliner sagged, it handled terribly (it is a massive vehicle)...overall just not a nice vehicle to drive. I finally donated it to charity since it was more expensive to fix than it was worth. |

Extremely impressed with this vehicle. I have owned a 96' 2001' models prior and this one SMOKES THEM ALL! The power is very very impressive and the 4x4 is equally impressive driving through snow and rain. My wife loves the auto start which even remembers on its own to engage heated seats and heat when starting with remote start. The nav and back up camera are very much appreciated options along with entertainment system for our little ones. BUY ONE....YOU WILL LOVE IT!!!!!!!!!! PS; I traded in my Mercedez G500 for this Yukon and have never felt bad for doing it. LOVE THIS YUKON.... |

I love my Envoy. The 30,000 mile tune up was a little expensive. Had to replace drums and break pads at 30,000. Thought that was to soon. The garage wanted 1000.00 to have them done. Had mechanic do side job. parts and labor less than 400.00 |

We been using my buddies Yukon for duck and deer hunting and you can't beat it, Rain, Snow, Its smooth riding and holds dogs guns and all the gear and gets 20 mpg to boot. |

This workhorse Suburban was very rough around the edges. With less than 100,000 miles it blew a headgasket. We also had a tire blowout on I-5 that luckily didn't cause an accident. I never felt very comfortable driving the truck and it just required too much repair given how young it was. |

I drove a GMC Savana 1500 cargo van for almost 3 years around the San Francisco Bay Area as well cities like Santa Rosa, Modesto and Davis. As a cargo vehicle the performance was amazing, capable to carry a lot of weight and runs smoothly with excellent brakes response. In the outside is a tough car. In the inside the seats arm rest are really weak, but it has a strong A/C. Without any mayor mechanical trouble other than replacing a couple brake light bulbs and a few fuses, I would say that the overall weakness is the low gasoline mileage. |
|
|
Very reliable truck with its 350 cu inch V8 and 4 speed trans its a deer hunting machine and gets decent mph about 16 highway and 12 city |
|
|
Inner door panels keep falling off and fuel pump went out twice at a cost of $700 not a very reliable van |
