2004 Chevy Trailblazer. I noticed a lot of other people as well as myself having an issue with the the idol in the vehicle as even whenever you turn on the AC it usually just shuts off the whole car because there's not enough the idol is not high enough something's messing with the the idol control module or something other than that. And it was it was idling real bad probably between five and jumping down between and just shutting off when you turn on the AC pulling down the RPM. And I mean I looked under didn't find any air hoses and the lines that were loose really I didn't see anything out of the blue so I just went directly to the you know idol it's an electronic idol control so I pretty much just took off this whole system right here just take off this little there's a strap right down there that holds on this pull this aside after you take two bolts right here there's a hose underneath plug it pull that whole system aside and then you'll see the throttle body right there you're gonna want to you're gonna want to actually take off the whole the whole module the outerwear throttle body so pretty much there's just right here as you look from the side there'll be four bolts going all the way around it and it will take off this whole system right here and inside of the system you're just gonna see it right in the throttle body right there you're just gonna see a whole bunch of gunk all you all kinds of different things over the years that you know got stuck to the sides and just go get some get some carburetor cleaner I'll show you what I did exactly to mine I just used in pretty much the regular what we call throttle body carburetor cleaner just whatever I had in the garage pretty much and I cleaned it out took some napkins those sharp napkins and they had all this just all this gunk in there you can see it's just real real messy and winning the edges just clean every little inch of it and then that actually helped the problem I put it all back together and started up the car and actually the idle went fine I wouldn't believe something you know something that I wouldn't say mine or something that simple as cleaning it out would actually help the idle a bunch because it was pretty much shutting off the car you can have the AC on without the car shutting off and one other thing you do have to do that I have to mention is there's the PCM it's since its electronic has to reset itself so if you have to do actually before you after you clean it out put everything back together get in the fuse box here and you're gonna see two fuses that I've focused a little bit you're gonna see two fuses number 10 which is PCM B number 28 right there PCM 1 you're gonna want to disconnect both of those which is gonna be 10 is gonna be right here this yellow one and then this blue one right here is gonna be the PCM 1 that one's gonna be B you're gonna want to pull both of those out for about five minutes and as well as disconnecting the battery right there the negative terminal or the positive sorry for the negative action disconnected let it sit for about I say five minutes plug it all back in makes you connect to that harness as well to the the throttle body idle motor right there make sure everything's connected close it up and I went ahead and I was surprised I didn't think it actually fixed the problem but I went ahead and started it up jump right up to around six six seven right in between and I was just fine over there that's with the AC on you see it doesn't even affect it anymore that's the AC off and better turn on the AC and just stays around six seven right there so that's that's not a bad celery usually the celery and your release it just goes way below and just shuts off the whole vehicle with this one staying just around that origin that it wants to stay in and that was fine it drives with no issues no power loss nothing like that I got a few codes which I'll put it down in the description below a few of the codes that I actually rang up whenever I before I actually started this whole a little cleanup and now I mean there's there's really no issue it's like a quick what 15 20 minutes probably 30 if you don't really know what you're doing or you don't mess with cars a lot it's pretty much just one strap over here two bolts pull this aside after you unhook that to pull it aside unhook this harness going into the the idle motor in the throttle body disconnected there's been before both holding on the the home module the throttle body pull it off take it out just go you know get some napkins cleaned it in you can move the throttle a little bit clean it underneath put it back in bolted back in put the air system make sure you connect it all the harnesses remember to disconnect 10 and 28 to the 2 pcm fuses and disconnect the battery for about I say like five minutes plug them all back in make sure everything's connected right start the vehicle you shouldn't really have any problems I'm assuming I just have to calm and problem with a lot of the Chevy's these I've looked up a little bit of forums and people have had the exact that exact same problem you do that I mean we'll have any more problems with they see the idling not really I thanks for watching subscribe to my channel I have a few videos I have videos every now and then going on common problems with vehicles that a lot of people are known to to have with their vehicles and just go ahead and
