These are it. I took them off to put a light bar behind the grill. My check engine light is on. What im planning to do is remove the harness from the shutturs and the small electric engine and reconnect it and hide it somewhere. Ill then celar the check engine light, really hope it works. I went small on the bar but they are super bright. KC Flex lights.

There are nubs that go into the motor that will need to be cut off of one of the shutters which will also make you have to cut the center part out of the frame. This will tease the shutter motor into thinking it's working correctly. If you just remove the motor from the housing and plug it back in you will continue to get CEL.

I made my own bracket to fit 3 small LED light bars in the grill without removing or modifying the shudders. I did have to grind down some of the rear aluminum housing of the LED’s that was for heatsink. Mounted it using the 2 bolts in the middle of the grill that hold the shudders. Shown here while test fitting with tape. I purchased a LED controller on Amazon & linked it to the Chevy Homelink within the cab.  Painted it flat black, they look & work great.

Code U1510 came up on my 2017 Silverado. It’s been at the dealership for nearly 4 weeks now :/. After “close examination” they have concluded that it is my shutters and my warranty is covering it. However, could this shutter issue be the reason my “main negative battery cable” went out as well as my battery now drained? 1st my truck went in with a check engine light and had that cable changed, after that it went back for the same code. It’s now been there 3 weeks and they’re saying it’s the shutters. How could these go out so soon? I’m in New Mexico and it’s hot and dusty as hell here. I just want my baby back ? Im hoping this is the end to that check engine light because I seriously don’t want to drive my 350k mile Camry anymore! Why does Chevy have these “codes” that don’t go to anything specific? Need help ASAP.

If they malfunction they throw a u1510 code and the MIL light comes on. Having this problem now. Truck has 38944 on it. Fairly common problem from what I’ve been reading. Under warranty, going to dealer next week.

Is this covered under drive train warranty ? Are they just changing them out ? I am getting the ECM P0005, ECM U1501, and ECM U1510 error codes. My remote start is triggering it which is weird

I bought a Grille Guard Barrier from American Trucks because their site said it would fit. It doesn't! No refunds! Scammed again! Can air shutters be removed? If so, how much will this effect the performance of 2017 GMC Sierra 1500?

Welcome to the site.

 

Yes you can remove, and yes like posted above you will get a CEL. 

 

You will not loose any engine performance if they are not there:

 

  • Shutters open in instances when cooling airflow to the engine is needed, like when towing, climbing a steep grade, or in other situations that powertrain temperatures rise above certain threshold conditions.
  • Shutters close on the highway when engine cooling needs are reduced, thereby reducing aerodynamic drag and maximizing aerodynamic efficiency by pushing more air around the vehicle.
  • GM says that the onboard computer system that controls the active air shutters is programmed to keep them closed as often as possible to reduce aerodynamic drag.

About time GM put these on gas trucks. If uou live in a cold climate they are for Fast warm up not to mention the mpg improvement esp in cold weather on hwy

I agree!  My truck warmed up faster this morning.

I cannot imagine this feature actually making a mpg difference but they sure talk a good game about it.

Move up north where -30 is the norm during the winter.  The crappy winter gas lowers mpg enough, these shutters do actually help.

 

Back in the squarebody days, a piece of cardboard in front of the rad worked too.

      Ac not keeping up

      By Aimatdeer · Posted

      I was using recirc/max air. Especially if it really hot i start out by lowering the front windows a little with regular ac the go to recirculation after a few and rolling windows up. And it does not have the newest refrigerant. It has per the info under the hood r134. Not the new r1234yf.

      AC diagnostic on a neo-classic Camaro

      By Atlas · Posted

      tldr; Shade tree mechanic stumped by variable displacement AC compressor.   Not Silverado related, but for my 2000 Camaro SS. I've never really used the AC since acquiring the car a good handful of years ago. I plan to take it on a trip this summer so I wanted to make sure the AC was in good shape. On an 73 degree day in the shop with the car idling I set the AC on "Max", temp set to cold, and fan on hi. The compressor turned on and air turned nice and cold.   I let it run for several minutes but noticed the compressor never cycled off. The engine was up to temperature enough that it began cycling the cooling fans on high. I had a set of manifold gauges hooked up and it was consistently at about 25 psi on the low side and between 200 and 225 psi (warm engine) on the high side. Per temperature charts, the low side is low (should be 30-35) and the high side is a little high (up to 170 per chart). I read the low pressure as potentially being under-charged underscored by a continually running compressor This was also underscored by temp readings of mid-20 degrees at the vents. Not just cold, freezing cold. Switching off the AC but leaving the HVAC fan on high produced a deluge of condensation underneath the vehicle. I was getting ice buildup on the evap core most likely.   The low reading (25psi) concerned me that the compressor wasn't switching off so I swapped out the pressure switch. No change in behavior, still ran constantly.   The AC clutch works fine as it engages/disengages with the HVAC switch on command. The compressor relay is good as I swapped it with two different known good relays just to be sure. Having eliminated that, and the pressure switch, I added refrigerant, thinking the constant run and low "low" pressure were signs of a slight undercharge. Makes sense, the car is 26 years old and it doesn't appear the AC system has ever been touched.   Adding some R134a didn't meaningfully change the low side pressure. And that's when a lightbulb flashed upstairs. While I consider the car "old", it's possibly "new" enough to have a variable displacement compressor. Did some reading and sure enough. Dangit. I don't work on these for this reason.   Adding refrigerant means the compressor will just compensate and won't really change pressures until it's severely overcharged or undercharged. But at least I wasn't getting ice/frost anymore, but instead high 30 degree temps out of the vents. That's more normal, but with variable displacement now I have no idea where my charge level is at. It's probably overcharged now. The high side even with the engine radiating serious heat was never really over about 225.   The static pressure at room temperature is dead on, before and after the charge. Both high/low equalize after some rest.   I'm thinking I'll need to take it to a shop. I want the proper charge level so I'm not working the compressor too hard. The only way to get an accurate charge is to evacuate and then re-charge with the exact amount specified for the system -- at least that's what I'm reading.   Anyone here with modern automotive AC knowledge?

      Mine is in the shop for the AC now. While it did get cold after a bit, it would take a while to even start to cool the air at all. Turns out the compressor was bad and cycling.

      I call B.S. when I first moved to Texas my first house would only cool to 80 with the Texas heat. The AC tech said it was normal at 100 degrees outside. I remodeled the house put in a new AC. I could hang meat. My cars may need recirculating to start. Once moving it switches to regular AC and I could hang meat. Living in Texas no one would put up with only 20 degrees difference.

      AC in home or auto only cool down 15-25 degrees from outside temp, but what will help is to put the ac in recirc mode this will recirc the Inside cabin air rather then trying to cool down the outside hot air, I always have mine in recirc mode.
