Transfer Case Control Module - high pitch electrical squeak

[Jeffer09]

Hi. Has anyone had the high pitch electrical squeak in all but 2wd coming from left side of dash? I saw some earlier posts and was hoping someone who had it fixed could tell me if it was the transfer case control module and what the dealer did to fix (just replaced the TCM?) ? Also, can someone private message me on where you had it fixed so I can have my service team reach out ? There does not appear to be a bulletin on this issue yet according to service team.

Thanks!!

All. Hello. New TCM installed today. Did not fix electrical noise. Will try acoustic foam.

Mine also makes as odd, very low volume, very high pitched noise when in anything but 2HI. Honestly I don't hear it most of the time but I'll probably need for someone to look at it at some point. It would be kind of annoying if they need to wrap it in foam in order to make the sound stop. Just make a switch that doesn't make noise.

I'm having this issue as well. Amazingly, looks I'll be self-insulating the TCM on my new $75k truck soon. Wow

Well my truck is on the dealer one more time, the GM represent is going to be involved now and they have to make a decision about my car I have enough all ready. Or they fix the grinding noise and rumble or I will leave there. At this point I don't care about this is not a lease so I do not going to live with this. Also have 3 brake light full of water,drive seat move all over and some others manor issues. Let see what happens. [emoji35] [emoji35]<br/>

I just posted about this as well, before I saw this thread. Really annoying noise. Has anyone cured it with insulation?
