So I just got a 2018 Silverado 2500 and am wondering if anyone has experienced this in there’s. when I turn my truck off and then open and shut the door to make the radio turn off I can still hear what I can only assume to be the fan in the radio stay on. If I lock the truck it turns the fan off for a second and then it comes back on. If I push the power button on the radio it shuts off but again comes on. Anyone have any thoughts or does this happen in anyone else’s 2014-2019? It didn’t happen in my 2016 that had the same infotainment center that is the reason for my concern.

Dear All, I've changed the original belt driven radiator cooling fan in my GMC Sierra 2004 to an electrical driven type and want to know what is the best alternator to install to overcome the amp loss without adding/modifying alt. bracket/holder or wiring connections please? Regards,

Has anyone experienced a similar issue? I have a 2019 Silverado trail boss and when you turn the fan on, whether it’s ac or heater, there is a noise that is not normal. It comes from the passenger side inside the dash area. It’s not a loud noise and if the stereo is on you won’t hear it. It sounds like the fan motor is off. I wouldn’t bother taking it in if all trucks made the noise but they don’t. I had the dealership take me in another trail boss and there was no sound, just normal wind sound. They changed a bearing saying that was the issue but it is still making the same noise. The second time I brought it in they said they are reporting it to GM. I brought it in today and the service desk worker said it’s “normal”. I asked why the others don’t make the noise and he said it’s “normal”. Obviously not normal or they would all make the same sound. Anyone know what it is?? -
I have a 2008 NBS crewcab 5.3 4x4 with digital dual climate control. I recently started having trouble with my ac not working right. Didn't think much of it at first as it was almost like a voltage type issue with the fan blower slowing slightly on occasion under different engine loads. Started getting worse, with a lot of sporadic panting, and now very seldom works correctly, sometimes even not at all. Does not matter if its on auto or manual. Seems like right when you start the truck it works strong and correctly for about 3-4 minutes, then it goes to panting and quits. If I turn it to manual and hit the max fan button it will come back on but not always the strongest level. Levels below 4 seem to pretty much turn the fan off. There is an odd light clicking/clunking that I get back in the dash, could just be an actuator motor. Sometime it sounds like a motor that is getting ticked on and off sometimes too. I did install a new radio a month ago, AC seemed to work fine directly after. I know some of the older silverados could get messed up with the harnesses that you used on them. I have installed a new blower control module (resistor). This did not fix it. I know there are at least a couple fairly cheap sensors that are involved, but I am leaning toward it being the actual head control in the dash. What do you guys think? Watch this video, and turn it up. Any help is appreciated. [media=560x315]http://www.youtube.com/watch?v=BGymxNl9y2w[/media] -
2015 chevy 1500.. 3400 miles. A couple of times the heat didn't work. It always did "next time".. the other day I had to take a 3 hour drive.. it didn't work the whole way there...stopped for an hour..headed back still with no heat (it was 42* so it was not pleasant) Took to dealer - they said they cant find anything wrong, of course, and of course the he was working fine. Its only done this a couple of times in the past 2 months now. Anyone experienced anything similar? It blows out air, and it will adjust the fan speed properly (or what I'm guessing WOULD be properly if it was blowing out heat) based on the temp of the cab. Even when taken off of auto and just turned temp to hi and fan speed up, with AC button off, it was still blowing cold air. Any ideas? Could it somehow be user error? (doubtful) Also when the AC button is on, even when its on heat, is the AC really still running? seems dumb that lights always on even when you have the temp high and its blowing heat.

I have a 2017 Denali and have had since new. I noticed that lately the HVAC blower fan cycles on and off while the truck is turned off, just after driving it. Does anyone know why this is happening. I've noticed that the amp meter is charging more and not dropping down like it used to when the truck is new. I was wondering if the battery is circling the drain and not providing enough amperage. I also noted that after the truck was parked for a couple of weeks, the compass settings on the Navi changed. Thanks in advance for the help. -
2013 Sierra Rising Temp Gauge No AC and No highspeed fan
Michael Lauze posted a question in Ask the GM Technician
OK HERE WE GOOOO!!! I have a 2013 GMC Sierra Nevada 4.8. I live in Manitoba Canada where for 10 months out of the year it is below freezing! Last week we had a warm day so while my wife was shopping I decided to turn on the AC while I was waiting for her, I got the 3 flash light and it went off, I thought it was because it was to cool still. Than I noticed me temp gauge start to rise. I have owned this truck since it was new and pull a small 5th wheel around with it I have never seen the temp gauge move before. So I sat there waiting to here the fan kick on... It never did, slowly the temp went back down, but within 15 minutes it was back up again. I'm wondering is it possible that a fan relay could be gone and that is why the highspeed fan never kicked in as well as why the AC won't work. I also tried it yesterday and had the same problem.... I'm stumped! -
Hello, my name is Kyle. I am new to GM-Trucks.com and am just starting to really get into do it yourself projects. I will be taking my 1987 GMC S15 pickup down to florida next week for the Daytona 500 from New Jersey. But first I need to replace the belt tensioner. I understand the part of taking it off and putting the new one on but in videos I keep watching them keep mentioning something about the torque when I tighten the new tensioner. When tightening it I don't just tighten it with a socket? I need a torque wrench? Any help or tips you guys or girls can provide me with for this project would be greatly apprciated. Thanks!!! -
So today when I was leaving work I noticed that my fan on my heater was extremely loud.....I know normally it is loud when on full blast but this sounded like I had a generator running...It felt like the whole truck was shaking...It only did it on the highest fan setting and one down from the highest...and also did it in both heat and air....It did it through the entire drive home....There was a crap load of snow here today in Ontario...It has since stopped once I tried again after I shovelled my driveway.... Any thoughts on what it may have been? Cheers -
Hi All I have a 2007 GMC Sierra new body style and when I have the heater on it might blow on my feet like I have it set to do but then out of the blue it will change to the body vents and the fan speed will also change on its own. Any idea why this might happen and how to fix it? Thanks
