Power Window problems

My power window on the drivers side went down today but now it won't go back up!

 

If I press the toggle for the window to go up it just makes a clicking noise and the window just sits there. The passenger side window works fine. I removed the plastic cover over the switches and there are no loose wires where the button is, so the problem appears to be somewhere else. I am just in the process of taking off my door panels, any help is appreciated.

 

 

My trucks is a 1999 new style ext cab

 

Thanks,

Sounds like the regulator is shot.

I had a glass company do it for $283.50 last year.

I would suggest ordering through a discount dealer such as 1stchevyparts.com if you are doing it yourself.

your motor is probably shot, or your wires that work the pully system are shot, or one of the brackets has come undone.

 

Go on to eBay and look up window assemblies for your truck, brand new will run you $60. Your Parts Store from Texas has great customer service, reasonably shipping, and a quality product. I had to buy one for my passenger and drivers side now (so i would order two if were you). they work better than OEM, IMO.

 

when it happened to mine, part of my window was still up, so i grabbed it and pulled up while pushing the button, it helped it along for a week until my parts came in.

 

If you take the door panel off you can see pretty easily how the whole assembly works.

 

I have a 99' 1/2 ton ext cab shorty new body style too, mine happened at 120,000 miles.

 

hows your tranny? :cheers:

To quickly test it out, unplug the motor and jump across the connector (harness side) with a volt meter. There should be 12 volts when you press the switch in either direction. If so, the motor is shot, if not, the problem is in the switch or circuit. You can actually use a test light for this since it isn't a sensitive low current circuit.

chances are once you get the door off you will see that the brackets have come loose or the wires have tangled. in which case the $60 is worth it. I had fixed one, rerouted the wire and everything just to find that a perfectly functioning motor was eating the wire inside of it.

WOW! Thanks for all the replies.

 

Got the door off and had a look. Nothing looked wrong, so I just unplugged and reconnected the wires at the motor. That seemd to work, although I notice when the window goes up in makes a squeeling sound like it is rubbing on something. Right now the window is up so I leave it like that. I will take a better look on the weekend when I have more time and it is still daylight.

 

Thanks again!

 

dustin07: tranny seems ok I have a larger tires on and I did the fluid around 50000kms ago. I had Westers adjust the tranny for the tires so far it has been ok. 25000kms with the tires and 20000 with the westers. Are you having tranny issues?

I just changed mine this week (broke the window in the process... make sure the rubber piece is in the clamp :cheers: ). Anyway, when the glass company was installing the new window, he suggested lubricating the window track with WD-40. Try that... it might take care of the squeaking and creaking. Plus... less resistance on the window = less stress on the motor.

 

Also, mine worked intermittently for awhile before the motor finally bit it. Replace the motor and regulator now before the thing gets stuck in the down position at a drive thru in the middle of winter.

YAY!! Same thing happened to me like 2 years ago. My window was held up with vise grips for like 5 months! Finally found a regulator on eBay for 50 bucks so I snatched it. Id bet the cables in your door popped off the pulleys and its a big mess in there. Mine was anyway.

My windows go up really slow.  I took it to the dealer and they supossedly replaced the motors, but its still slow and takes a long time for them to go up.  Any info on this?

 

 

 

I lubricated my window runs with spray silicone when they were doing that and they sped up immediately...couldn't hurt, may even extend the life of the window motors a tad.

It's sad that such a great company would make such a CRAPPY window assembly!! Whats even more sad, is if nobody's problems started until after 70-100K miles then they (GM) would probably think it was a success!

I've heard that it's a crappy one, but i don't know. mine went out at 70K and the rebuild has had no problems over the last 52,000 miles. I change the fluid a little bit more often now, and i'm shopping a tranny cooler.

 

Also, mine worked intermittently for awhile before the motor finally bit it. Replace the motor and regulator now before the thing gets stuck in the down position at a drive thru in the middle of winter.

 

Mine was the same way. funny thing is, on my driver side, i was suddenly not in a rush to fix it. took pulling up to a coffee drive through or fast food about half a dozen times in the rain (think Washington/Seattle) before i finally jumped on it!

I was thinking about the lubrication as well. I think I will try that first but also look into a new regulator. Tried the window a little today, down only half an inch and it went back up ok but its better to be safe with winter coming. I think I remember the owners manual recommending lubrication of the weather stripping as well, so maybe I should have been doing this from day1...

 

Hey budhayes3: I take it you are a fan of megadeth. You going to see the Deth on their tour? I just moved to Moncton NB and no concerts ever come close to here so I plan to fly to Boston and my brother will join me from Toronto.

Funny you should mention the Deth tour, I just found out they were touring last night! I'll probably miss them though, they're coming to my area on a week night...kinda tough with work and all. Do they have a new album, and if so, is it better than the last 2?

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
