#3218 of 3260 2004 yukon driver's side power window by goodjeans Jun 19, 2008 (6:00 am)
My Yukon's driver's side window was working fine. Then it stopped all of a sudden with just a clicking sound when I hit the button. A little while later it began working again. It worked for a week, then rose slowly this morning. Is it the motor? What could be the problem. The other three windows work fine. Thanks. I am in the wrong forum but couldn't figure out where to post on gmc Yukon.

Replying to: goodjeans (Jun 19, 2008 6:00 am) If your Yukon is still under warranty, bring it to your GMC Service Department and have it checked/repaired. Otherwise, I would remove the switch panel out of the handle and disconnect the plug to your driver side window (make sure you know the wiring scheme first) then by-pass the switch to open/close the window with a jumper wire (probably a 12 or 14 GA wire) to determine if its the switch that's faulty or really the motor...   PLEASE NOTE, if you jump the wrong leads, you may potentially fry the motor and even your electrical system, so do this at your own risk. Make sure you know what you are doing, or leave it to your GMC professionals. Good Luck!

Replying to: goodjeans (Jun 19, 2008 6:00 am) GM is famous for motor failure on their power windows. 99% probablility on that one. Rarely, if ever, does the switch fail. Replies to this message: steve_ (Jun 19, 2008 11:28 am) obyone (Jun 19, 2008 12:59 pm)

Replying to: obyone (Jun 19, 2008 11:19 am) Seems odd to me that the motor wouldn't just quit, but would try to work in fits and starts. But I'm no mechanic... (but I do have a window switch in my Nissan that carbons up now and then and gets flaky). Replies to this message: obyone (Jun 19, 2008 12:59 pm)

Replying to: steve_ (Jun 19, 2008 11:28 am) At one time GM used to sell the switch and motor together. They had so many failed motors that they discontinued the practice in order to save money on the switches. Especially when performed under warranty.   Been there done that several times. 2000 Silverado, 2002 Yukon Denali or the GMT 800 platform.

#3224 of 3260 2005 Yukon 4wd SLT by gmhellman Jul 30, 2008 (3:06 pm)
I just purchased a loaded 05 Yukon SLT with 56000 miles for 18,550 from a dealer. I am just wondering what things/hardware people have put on their engines to get a better gas mileage return. Has anyone tried these new pulseplugs that I have seen advertised in MotorTrend and TruckTrend? Are they really as good as they say in terms of mileage and gas mpg return vs per se a platinum or platinum four prong plug? K&N air filter vs air intake?   Thanks Replies to this message: obyone (Jul 30, 2008 3:21 pm) rsht (Jul 31, 2008 6:19 am)

Replying to: gmhellman (Jul 30, 2008 3:06 pm) Save your money. Good wires and plugs can be found at any auto parts store as long as they are platinum. K&N? forget it. Course there are a lot of people that have purchased one including me. For myself all I gained was incab noise and nothing as far as mpg. I've uninstalled mine and sold it on ebay.   There are those that will swear to mileage increases and power gains, however, thrown on a dyno will result in an added bill for the dyno testing and results that will certainly disappoint.   My 2 cents.

Replying to: gmhellman (Jul 30, 2008 3:06 pm) I would make sure all the oil and fluids are fresh with new filters where applicable. For the engine, transfer case and axles, I would replace the old fluids with synthetic oil and new gaskets. If anything else, I would try a bottle of Fuel System cleaner too. I agree with the "obyone" about using a new set of platinum plugs and good quality spark plug wires. If you only want more power and don't care about the mpg, then consider those after market add-on stuff, like the air filter/kit, flow-through exhaust system and etc. I am one of those people who have been there and done that... and learned my lesson. Oh! also to keep your tire pressure in proper rang will help some too on the mpg.
#3227 of 3260 Thanks for the help by gmhellman Jul 31, 2008 (8:53 am)
I appreciate all of the responses. I am a huge supporter of Mobil 1 synthetic and will use that at the next oil change. I plan on getting a fresh air filter asap and will change the tranny and diff fluids on my next service. The vehicle only has 55000 miles or so on it so when it hits 100000 I will change the plugs and wires. Any comments on a high quality/good reliability brand of air/oil filters, and plugs and wires? This vehicle has been impeccably maintained and I will keep it that way.   Thanks Replies to this message: rsht (Aug 01, 2008 4:35 am)
