Thanks for the video, what I did notice is that you didn't take the negative cable off the battery and that might be why you didn't have the security light on

Pcmofnc does pcm tuning also. Awesome company. PCM of NC. They sell a lot of stuff for our rigs. Electric fan works great. I paid 178.00 and they tuned one for a CIA no cats changed the shift points and the secondary air pump and deleted other things.

Amen bro 💯

Module…the switches are modules now and supposedly they have to be programmed…however, I’ve replaced things that “needed programmed” and it worked just fine without any programming…I noticed on my 05 that I don’t have a chipped key…and almost all the options in my pcm are turned off…lol…which means if I fix these updating data etc I’ll probably get locked out of my trailblazer cuz it didn’t come with the chipped key …crap

I’m having the exact same issue…. Gonna give this a try.

Mine is still good, no more ticking!

17:50 it wont come back to them... there are waaaaay too many car dumb people out there that NEED to go top the dealer... its the first place they go and usually take the hit cuz they need their car done quick and have no inclination to fix it themselves. even a switch panel on the door that takes 20 min and socket/screwdriver to do... even that makes peoples head explode. changing this pcm is easier that changing the door switches... but people would rather attempt to teach a dog to drive than do either the switches or pcm... people only barely know when to change their oil(or what kind their car takes) and neglect all other fluids until their shits broken...thats why dealerships will never "get whats comin to them"

Not seeing it in other comments, idle on our two is 700 RPM. 250K miles on the 2004, 115K on the other 2004. Edit, switches do not need to be programmed.

Thanks

Dude. Did you try to just factory reset the old PCM?

Idk why the dealers refuse to do updates…they should have to by law considering how much it effects on the engine having outdated data on the pcm…I was gonna buy a used one simply because they program it to the vin and update everything before they send it out…

Well the used one in this video failed a month ago

Where did you order that pcm from? Ive been having a similar problem with my 2002 trailblazer and think this is the last thing i haven't tried yet.

I ran into a problem with the junkyard PCM it wasn’t programmed to my vin number and was flagged during a State inspection

Can I get the information on pcm where you got it from. I’m experimenting similar issues with my 2002. Mine starts acting up in hot weather.

Speaking of "programmed" I'm sure some of the dealers are programmed to convince you that your old one is junk and time for a new vehicle.
