Sierra89

Hi All, I found a weird electrical issue in my 2013 Silverado today. When 2 power window switches on the drivers side window control are quickly pulled up and then released, the radio goes dead then restarts. This only happens when 2 switched are quickly pulled up and released. If they are held up for a few seconds then released, no problem. If they are pushed down and released, no problem. Does anyone have an idea what could be causing this? I find it strange that its only when 2 switched are quickly pulled then released. Otherwise there is no problem. It has the BOSE with navigation if that matters. Thanks for any thoughts or insights.

Thanks for the replies guys. The 'Bourbon' has 140,000 miles on it. The only reason I even thought about it being an issue is because my Sierra is up around 200,000 and I have not noticed the humming. When did GM start using the returnless fuel system? is it on all truck models from then on? Thanks again,I have no problem swapping in a new pump on an almost 20 year old vehicle, good peace of mind. Cheers.

Hi all, I just picked up a 2005 Suburban Z71. It's in great shape overall, but of course has a few items that need attention. I have noticed that the fuel pump is humming loudly, louder than any of my other trucks. Is this a sign that it's beginning to fail? If so I'll prioritize it's replacement. The Burb is closing in on 20 years old so I wouldn't be surprised. Thanks.

I was in the same situation as you exactly a month ago. I ended up going with a 2013 LTZ. I liked the idea of buying a model near the end of a cycle. I also am a fan of the 07-13 style, especially the later front end. I found a one owner with all service records, he even kept the original window sticker. I plan to keep this truck for a long time so we'll see how it turns out. That said, I have no issues with the 2014+ model, but the later models are still a bit out of my price range. Besides the updated infotainment, the 2013 has pretty much everything I'd want from a more modern LTZ/SLT. I was pleasantly surprised by many of the options in the 2013 high trim models. IMO, one of the biggest things is not to be hung up about getting the best deal. Paying a bit more now for the right truck could save a ton in the future. Good luck with your search!

I just has an similar issue. When the ac was on I would hear an intermittent whistle. I had the system checked and it was low. It was purged and refilled with the proper refrigerant and works great now with no issue. As a side note, mine was also blowing condensation out of the vents. Apparently who ever topped up the system before I owned it used the wrong refrigerant and broke one of the pressure ports, which was causing the condensation.

Awesome thanks. That's about the size I'd like to run. Having only a 55 sidewall makes me a bit nervous for working the truck and I have no desire to level it at this time. I drove the truck home a week ago and I gotta say I really like this rig. The Check engine light came on on the drive home and I scanned the code and it came up oil pressure sensor, which was no surprise. It went out the next day. I'm thinking I will leave it alone until it comes back on. The oil pressure gauge was a little low on the drive home in my opinion, but when I changed the oil the next day the pressure was where I'd expect it to be and has stayed in that range since. I wonder if the CEL was from the truck sitting on the lot for a bit. Anyway... thanks for the good advice guys.

Thanks for the responses guys, I'll check out the Range AFM disabler. Glad that it sounds like MPG is not effected much if at all. As much as I would like decent MPG, this is a truck and long term reliability is way more important to me. Yes she has the 5.3. This truck has the 20inch rim option. The rims look really nice but I wasn't stuck on having such large rims. I'd like some more sidewall because I do use my trucks as a truck. Does any one know how tall of tire I can put these on these rims without any modification? I believe its a stock P275/55R20 tire now, can I go to 275/60 or 65? Thanks.

Hi All, Its been awhile since I've been active on these forums, but I'm back. I've really enjoyed my Accord V6 coupe as my daily driver, but with a growing family being active outdoors it was time to get something else. I just traded it in for my 3rd GM truck and my first Silverado. I started with an 89 Sierra, my wife and I still have our 2006 Sierra and now I'm adding a 2013 Silverado LTZ to the fleet. The first two trucks were (and the 2006 still is) very reliable, I'm hoping this 2013 will be as well. It has about 70,000 miles and is a one owner truck. Clean carfax and service history, heck... it even has the original window sticker with it. I'm going to tune it to disable the AFM, and look into reinforcing the dashboard so it hopefully doesn't crack any time soon. Other than that i should be back to reading the forums more and participating in some conversations. If you have any suggestions for a new GMT-900 owner don't be shy. Oh... and since this post is worthless without a picture....

Hard yes they should keep it. Push button start is OK with me, but no need to replace the column shifter. I wouldn't be too upset with a console lever, but thats it. Absolutely no knobs or buttons.

I had a similar issue. Turns out a rodent made a nest under the fuse panel and relay box under the hood and was dining on my wiring. Judging from all the damage he did by eating wires I'm amazed that the overheating at idle because the fans were not kicking on was the only sign of the problem. This was earlier this week, I'm sorting out and fixing the wires as we speak. Best of luck sorting it out, remember to check for animal damage too.

Its been a while since I posted so here's an update on my 06 Sierra: engine: 5.3 with 3.73 gears, (tow package) I've replaced: O2 sensors, knock sensors, evap solenoid, brakes, tie rods. There's probably more but can think of it now. With only 130,000 miles its been a very reliable truck. I have some burned out lights on the radio and climate controls that bug me, but not enough to replace them yet. It has the intermediate shaft clunk, but as long as I disconnect it every 12-24 months and move it back and forth for a few minutes it goes away. I am planning new plugs, wires, trans filter and fresh oil for transfer case/front and rear axles within the next month or so. The rockers and door seams are getting rusty so I'm going to need to give them some attention as well soon. My other vehicle is a 2011 Tdi which I love but VW's offer to buy it back is too good to turn down. I'm trying to justify buying another GMT-800 to replace it, but the reasonable part of me is saying I need 2 trucks like I need a hole in the head....

I have a 89 F44, I know they came with the 10 bolt rear end, 6 lug. Mine has it and I know thats how it came when it was new. Maybe you could order it with the 14-bolt rear, that I don't know. Cheers,
