Having the same issue on my 2016 Suburban. There is actually no resistor on these trucks for the front fan, rather it's a circuit board attached to the blower motor itself that controls fan speed in relation to inputs from the rheostat-style dial on the HVAC controls. I have seen a post on one other forum where a guy had his get wet due to a leak and replacing the whole blower motor/circuit board assembly solved his problem (I think). I'm actually replacing mine today in the hopes that it solves the problem. If that's not it, I'll be checking my G218 ground posts under the dash by the windshield as outlined in this guy's video: If that's not it, I'll be stumped. It doesn't seem like a lot of K2 truck owners are having this issue right now but I assume more will as time goes on.

I guess that wouldn't necessarily "hurt" anything to try. Although it may just transfer the stress to another area and crack elsewhere. Honestly I think the only way to truly prevent this from occurring is to replace the condenser before the failure happens, which I think most agree would be silly. Food for thought - my 2016 Suburban is at 95,000 miles and still on the original condenser. Knock on wood...they don't all fail early.

The mod BigBlue posted is what I used. If you have a 17 or earlier truck, your DRL LED's will be dim even if you do the Tylus mod. Franjimo24, the 18 and up trucks had the bright LED's. All models.

I for one would like to know how you got GM to replace a transmission on a vehicle that was out of warranty. Quite a trick you pulled there. I'll be saving this post for when mine goes out.

Just in case anyone starts having this issue... https://static.nhtsa.gov/odi/tsbs/2019/MC-10163854-9999.pdf There's your golden ticket. Just had mine done last week. I was sure it was an AFM lifter failure, turns out it was #3 and #5 injectors gone bad. Keeping the notice for when the others go out...

This is distressing.

Sounds like a Jake Brake! haha cool if you ask me! No really, I'd be interested to hear if you confirm it's this valve. Looking at disabling my AFM and if I do, probably won't need the valve any longer. tlaw91 do you see a lot of these failing?

Yeah I spent about 6 hours on this site and immediately ordered a Range AFM disabler for my 2016 Suburban. Thank goodness for places like this.

It would appear that fuel injectors are a relatively common failure point on the direct injection GM V8's starting in 2014-ish and can cause misfire issues (and therefore a CEL). It would also appear that fuel injectors, for whatever reason, are not covered under the GM factory warranty. I learned this after owning one of these trucks for one day.

Thanks for the responses!

I know I'm new here and have been posting about this elsewhere, but can someone who has experience around here tell me if there have ever been any complaints of the Range causing mechanical engine problems?

I'd be curious to hear from you guys who have had one in on a 2015+ truck for awhile and how the Range is working. I'm thinking about getting one for my 2016 Suburban to avoid AFM related lifter issues down the road.
