Ok one low beam works, the other does not. I swapped both sides with existing bulbs and the former good bulb does not work on the passenger side so that eliminates it being a bulb issue. The fuse was checked under the hood and swapped with another fuse but to no avail. The high beam and low beam relay appear to be identical so I swapped those since I have working hi beams and that did not work. I have power to the fuse, to the relay, and to the light. What's left or what am I missing here that would cause only the passenger side low beam to not work? Please Help...

 

Thanks

Now I have confirmed I have good grounding at the headlamp and the pigtail connection by the low beams. If I have a good ground, constant hot when lights are on, good fuse, working relay........Why do I still have a low beam out of this POS! WTF....... :(

This is a great forum, nobody replies to anything. I guess everybody is working overtime to fuel their gas efficient GMC products.

 

What the hell do you call this?

I'd say it was a response or two....once again, if you've got a good ground and 12VDC then you've either got a problem w/ the connector or the bulb is crapola!!!

      Yesterday we brought home a 6yr  old Havanese dog from a nearby SPCA.  We've had her for 24 hours and we are delighted with how well she is adjusting to her new home.  It  was a huge decision to adopt a dog at this stage in our lives but we believe we made the right choice!   it was reported that her first 6 years were ones of neglect.  I think she's already realizing her life is going to get a whole lot better...  so is ours!

      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

      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.
