2004 2500HD, dash lights and radio stay on when the drivers door is opened. my front speakers are out so I dont know if there is a chime or not. Stock radio. thoughts?

your door chime comes through your speakers, from your radio.... just check your front speakers, if both are bad replace. this should fix it.....it did 3 of mine.....

So I have come to the conclusion that I need to replace the whole door latch inside the driver door. Does anyone know where to find one? I have tried LMC, all the major big box auto parts stores, even the local junk yard, no one carries them.

do you have the factory radio in??? if not you will need to buy the radio interface with door chime..... plug and play.... goes between your radio and plug...........that is if you have a aftermarket radio......

yes I have the interface for the chime, when I turn off the truck and take out the key I get three chimes then when I open the door the radio and lights should turn off but they do not, I know the wires are all connected well inside the door so my conclusion is that the built in door switch inside the latch is bad and the whole latch mechanism needs replacing.

guys,!! wouldnt a scanner show data for the latch,?maybe a programming thing?

 

dont assume the latch is "bad" lmao

Most scanners will not read body codes... only OBDII mandated codes.

 

You didn't say what scanner you used, but I have tried various scanners that simply do not read body and chassis error codes unrelated to engine or emissions, even though I already confirmed through GM that the truck's modules were storing error codes.

I checked for codes and none were thrown for the latch. but still the door switch is not telling the truck the door is open.

how do you know that the switch is not telling the truck its open ? have you seen the data in the BCM ?

 

i think you have not

well, I did not personlly check the codes, the dealer did and I dont know what scanner they used. Now your right, I dont know that it is specifically the door latch that is the problem but hey thats why im here asking questions now isnt it. All I nkow is the radio and dash lights stay on when the door is open, that s not supposed to happen.

OK got to the bottom of it, best of all it didnt cost anything but my time. My front speakers went out due to dusty connectors so I had the door panel off to fix that and decided to pull out the latch and investigate. I did so successfully and noticed that the electrical switch/"actuator" (not really an actuator since I dont have auto locks) was only attached to the latch mech. by one screw, the other had broken off. I drilled out the old screw and added a longer one that goes all the way through the housing and it was as good as new. switch works great. Radio and lights go out when the door is open and i get the door chime. here are a couple of pics of the mechanism.

      I thought I was building a HD 3500 srw, maybe I was lost.

      Which 2027 engine will you choose?

      No doubt, I definitely agree with you. However, considering the 6.2 and 3.0 have been catastrophically failing with very little miles, I figured I would put trouble free. I’m at 18,4xx and still not a single issue.

      It’s never dry here but it gets hot. My 4 vehicles I keep at home drive an 18 mile loop. One 6 days a week. Two about 3 days each and one once a month. Only one goes on trips about 4 times a year 1000 to 2000 miles each time. One 26 years old gets driven once a month for 22 years. One 14 years old goes 6 days a week. The other two are recent at 2 and 4 years. All are performing normal no extra service other than that would be half of recommended or severe service in the maintenance manual. No extra water or steam out the exhaust or premature plug wear. I would consider an 18 mile loop would be enough. So apparently once a month at 18 miles for 22 years has kept the collector car running well. About 45 minutes a month.

      Transmission Temperature Hitting 220s

      By newdude · Posted

      It is working as designed.  NHT and non NHT trucks have the same exact transmission cooling setup.  NHT just gets a larger radiator.     The transmission cooler loop on these is as follows.     -Transmission out goes into an oil to water heat exchanger (item #1 in the first illustration below).  This exchanger has engine coolant opposite the transmission fluid and uses engine coolant to warm and then regulate the transmission fluid temperature when its in the operating window.   - From the cooler it goes to a thermal bypass valve (item #11 in the 2nd illustration below).  If the ATF has not reached the temp to open the bypass (194F), it loops back.   - When it reaches 194F, the thermostat opens and ATF then flows out to the oil to air auxiliary cooler (item #17 in the 2nd illustration) at the front of the truck.  From there it goes back to the transmission.     Your only fix would be to swap for the PPE thermal bypass delete block which will open the loop to the aux cooler all the time.  It will STILL run warm, probably 170-200F, but that's as low as you'll get it as its still flowing through the oil to water exchanger.

      Most say the oil temperature needs to above the boiling point of water to rid it of moisture and long enough to dry it. Many think that is about a hour at 212 F or more. Those people have never line dried cloths in a Midwest winter. Leave a pan of water sitting on the counter and eventually it all evaporates. So heat drives the time it takes. Water in oil under 175 F, the Nitration initiation temperature, is a minimum then for temperature and samples I've done that use Karl Fisher method say about a hour (in a healthy well tuned motor) over 175 F will dry it to under 800 ppm. Low enough to not be much of a factor. Motors with weak rings will take longer and the colder the air temperature the longer it takes.   On a cold motor there is also the condensation temperature. Blowby gases that contain moisture are subject to that cold cylinder wall, like sweat on a glass of ice tea. But also subject to the Law of Partial Pressures. Wear studies by GM and the DOD  indicate wear is a real issue below 85 F and a concern to 140 F but doesn't become a minimal factor until about 160 F. You know this intuitively when you see water vapor exit the exhaust pipe until the system gets above the dew point. It isn't magic, it's physics and it fascinates me. I know you didn't ask but....I over share sometimes. 😉    You keep the Camaro's high and tight.
