    Ok, who has dropped the tranny pan? How many curse words were dropped?

    What an engineering fail! The drain bolt was stripped so I figured not knowing if the filter has ever been changed I'd do it while I was under there. In my Dmax it's a 30 minute job so I figured this would be similar. Nope. I fought with this damn pan all freaking day long and took many unwanted...

    Gates WP missing weep hole? A quick favor!

    Hey guys, I installed a gates water pump in my Yukon today. Installation went smooth and no leaks so I'm satisfied so far. However my dad was asking about it so I was explaining it to him and I showed him the weep hole on the old pump (OEM) and when I went to show him the new one, I was a bit...

    Confused. Help with thermostat housing

    You couldn't be more right dude! Society has gotten to the point where people want instant gratification and answers, and for some reason people are afraid of admitting they don't know the answer off the top of their head. There's nothing wrong with not knowing and needing to research the answer.

    Confused. Help with thermostat housing

    Completely agree with you. I actually work in a similar role (different industry) and I regularly ask to call a customer back if I don't know the answer. I'd rather that than pretend like I know what I'm talking about and screw somebody over. Anyway, I've been in overdrive researching this and...

    Confused. Help with thermostat housing

    Thank you for taking the time to research into that for me. RA is actually the place I'm going to order from and I too noticed they listed 34702, but not 33910. I actually got 33910 from a post on this forum, the guy purchased the exact pump I'm getting and he got 33910 to mate to it. I had to...

    Confused. Help with thermostat housing

    Hey guys! My water pump sprung a leak so it's that time. I'm about to order a gates WP part # 45005 but I've ran into some confusion when looking at the thermostat housing to mate up to it. Basically I'm getting two different part #'s from different sources. Some sources say to use gates p/n...

    Can the dealer reprogram my HVAC control module to latest software?

    Hi guys. I've been trying to figure out why my rear HVAC won't change temp. The mode actuator works as it should, but the blend door actuator just overclocks itself to the AC side everytime I reset it. It doesn't go the other way (heat side). I've verified the actuator itself works by hooking...

    Yet another no heat/ac thread.... I know, I know.

    Sure thing! Just to clarify, part # for the controller, or the actuator? ETA: nevermind, i re-read your post and answered my own question. P/N for the controller I got is 15185639. I too came across a lot of conflicting part #s when researching which one I needed. Finally I just said screw it...

    Yet another no heat/ac thread.... I know, I know.

    Ok guys, I finally have this issue solved! Nothing drives me more insane than doing my due diligence and searching threads, only to find 80% of them don't take the time to update what the issue was, so here's mine. I first started with getting the correct part # actuator in there. With that, it...

    Yet another no heat/ac thread.... I know, I know.

    Anything helps, I appreciate any and all input! If putting a new module in there doesn't fix it I will probably resort to finding someone with a tech 2 to take a look. Man I've been reading lots of reviews on this Dorman brand one that's in there now and it's bad review after bad review, with...

    Can someone point me in the right direction.....?

    Duramaxforum.com I have an 01 and I can't tell you how much knowledge I've gained from that place. Not as active as it used to be but I tend to stay in the Lb7 section since that's what I have so the section for the newer ones might be more active.

    Desperation mode....Denali center console impossible to find

    Thanks guys, I appreciate the effort y'all have put forth, I'm genuinely shocked at how helpful this site is. And apologies for not updating this thread sooner. I'm actually in CO, so almost about as far away from NJ as possible lol. I am pleased to say though that I scored a color matching...

    Yet another no heat/ac thread.... I know, I know.

    That would be great! @915_Tahoe last 8 is 3J333442 Just to clarify, im in need of the whole hvac controller unit to replace this aftermarket knockoff one. I'm not seeing any OEM for sale (new) so I'm probably going to need to find used. If that's the case, would need to know what years would...

    Yet another no heat/ac thread.... I know, I know.

    Well son of a gun, that certainly makes things a bit more interesting. The 65 is more expensive too dang it!! I remember seeing the 75 and wondering. Well, I'll double check to see which one I got and if so, I'll return the 65. Thank you for that clarification, why do they have to make so many...

    Yet another no heat/ac thread.... I know, I know.

    Also, after looking at this closer, this part # seems to be for the module alone, I'm in need of the whole controller unit. I know I'm probably butchering the actual name for these parts, sorry for the confusion if i am.

    Negative, that's the one for the 2nd row that mounts to the back of the console. I attached an image of what mine looks like for the front. ETA: it posted at the bottom of my reply. I'm still on mobile so formatting is a bit tricky haha. Thanks for the photos man, looks like we do have...

    Yet another no heat/ac thread.... I know, I know.

    Yeah I must have the updated one. I used my Google-fu and I see what you're talking about for the 00-02 models. But the one I have is the all digital one, not the dials.

    Yet another no heat/ac thread.... I know, I know.

    Is that expensive?? I figured it wasn't bad assuming this dorman brand one goes for twice that at the parts store. Admittedly I'm not up to snuff on the going rates though. What is a going rate for a used OEM digital controller?

    Yet another no heat/ac thread.... I know, I know.

    Haha that would be a bit unnerving! Ok guys I think I may be on to something with the digital control module. Out of curiosity I had my girlfriend pull the module and send me a photo of the back. Sure enough as I suspected it's a Dorman product #599-211, not OEM so at some point in this...

    Yet another no heat/ac thread.... I know, I know.

    Haha, of course all these rather common failing parts are behind the dash! At least you see the bright side with your light sensor (pun intended lol). I remember my ambient light sensor needed replaced in the Duramax, which like your situation, required removal of the dash. I decided to take the...

    Yet another no heat/ac thread.... I know, I know.

    I replaced the one under the kick panel on the passenger side. I verified that's where my issue lies by manually flipping the blend door by hand. Whenever I did that, the air temp did what I wanted it to do (either hot or cold depending on which way I flip it). I pray I never have to change the...

    Yet another no heat/ac thread.... I know, I know.

    Thank you. I will look into the switch panel. I've been curious if that's what is bad and causing all these headaches. Any way to test it to be sure? I hate just throwing money at something. I'm hitting the junk yard this weekend, maybe they'll have some there. Also, thank you for the heads up...

    Yet another no heat/ac thread.... I know, I know.

    Ok guys, I know you've seen this a million times but trust me I've researched the hell out of this and I've hit a wall. 03 Yukon Denali. I had the typical no temp change on the driver's side, in my case the AC worked fine but heat did not. Ok for the time being but it's about to get cold in CO...

    Desperation mode....Denali center console impossible to find

    Thanks for the suggestions guys, really appreciate it! A yard about an hour from me says they have one in inventory so I'm just waiting on confirmation on that, it even matches my trim color so fingers crossed! Thank you Doug for finding that one and posting the link. If the one I think I found...

    Desperation mode....Denali center console impossible to find

    Thanks for the clarification! At least now I can stop racking by brain trying to figure that part out lol. Yeah the plan is to just keep going back to the yard until one pops up, it's only a matter of time I hope! Thanks again.
