ok,good to hear, being 10 plus years old i was thinking of changing them, but ill leave them be. thanks for the help

i have a 2015 HD 6.0 what do you guys recommend for new ignition coils. thanks

ok,its fixed!! i replaced the cowl grille plastic assembly at the base of the windshield. i also added some cloth tape to the area where it clips to the base of the cowl and the u shaped clips that go to the bottom of the windshield. all good, this truck has no other mouldings anywhere but the cowl piece.

ok,thanks. those earlier trucks are different at that cowl area. ive had it since new with the deflector,it didnt start doing this until like a few years ago. ill keep checking. Its not a whistle, Its a weird crack or crackling sound. very strange

yes, i took it off and its still there, it really sounds like right at base of windshield

on my 2015 Hd gasser i hear this crackling sound at highway speeds ,sounds like its coming from the base of the windshield. thought it was the cowl plastic covers, i took out the plastic pin clips and put screws in to tighten that up. noise still there. Anybody had this? thanks

hey does anybody know if you can use the square coils in place of the round coils on our trucks? my 2015 6.0 has the round ones now.

the leds are nice

hey,anyone seen this. i just installed Philips leds in my 2015 low beams,they work nice,but i just noticed that the high beams dont come on when the switch is in the Auto position,they only work when you have the switch all the way over to the right or pull back on the stalk. i still have regular bulbs in the high beams now. they did work initially when i 1st put the leds in. no codes in any modules either. hmm

ok,great. you felt the knock or heard it??

hey, i used to see when somebody had an issue with their truck on the forum here that GM would chime in with some help/guidance especially when the dealer isnt much help. i havent seen them on here in a while posting anything. Has anybody noticed this ? just wondering as i have a friend with a newer Colorado that could use GM s help.

we have a landscaper with a 2015 Hd 6.0 and hes been through 3 starters. it did do that when they went bad, just a suggestion.

hello,can you feel it or hear it, once in a while i noticed my 2015 Hd has some sort of knocking or maybe a little play i feel in the steering wheel when turning slow or maybe going around bends slow. shafts are tight as is the whole linkage. kinda of thinking its in the steering box.

my 2015 just a test to see if i could add a picture so it can be viewed right on the post.

cannot open the pictures, pretty sure you can load them into the post so that they are visable without opening anything up.
