nevermind, i opened the hood and traced the lines and it appears to be the pressure line. So i have that ordered now.

on my '03 TB with 4.2L, I was wanting to replace the power steering line(s) that run through that rubber block on the driver side inner fender. I removed the rubber block and the one line was super flaky rusty while the other one wasn't yet. I ordered the 2 return power steering lines that i...

On my 2003 Trailblazer LTZ with 4.2L , (Man. date jan 2013) I need help with which a/c delco part numbers are for all 4 pieces of the transmission cooler lines. Looking on ebay I think the 4 part numbers are ; 15817500, 15817514, 15817501, and 15817515. Am I correct in thinking if i purchase...

wow, thank you for the pics and information. now, for me to figure out the problem, how should I test those two wires; the light green and the black/white wire? While the high beams are stuck on, should either wire be hot? I do have a multimeter, i just need to know what to look for with those...

surely the problem is either the turn signal/multifunction switch or the BCM, correct? Is it the BCM that's attached beside the underhood fuse block? isn't a BCM under the left rear seat too? Which one would control the high beams? Which would you suggest changing first as it may be the...

hmm... I dont know if i should attempt that. My next question is how the heck did the high beams get on to begin with? I never turned them on. The turn signal switch never got pushed forward to high beams today and i never saw the high beam indicator on the instrument cluster. I sure hope it's...

I did swap the relay with the one next to it and still the same behavior. Once the high beams are turned on, they stay on until the relay is removed. Then when it is reinstalled, they stay off until they are manually turned back on.

on my '03 TB today, once i got home and shut it off and went to walk in the house, i turned around and the high beams were on. The headlights were on this afternoon while driving because of rain, but I never turned on the high beams nor was the indicator on. So I tried different combinations of...

When i put my newly tuned ecm in and started it and drove to town, my mpg readout stayed at 0. i started to panic but after i shut it off and restarted it, then it started working again.

on mine, it was the charcoal canister was plugged. i'd taken the vent line off going to the tank and blew through it and could hear it blowing into the tank. i took off the vent line going to the vent valve and could blow through it fine. The only thing left that it could have been was the...

So you are saying that the computer messes with what the temperature gauge shows just like it does for the oil pressure gauge? I have seen it explained why GM did that with the oil pressure gauge, but why with the temp gauge? Is it because like was just stated, that the 4.2L likes to run at like...

OMG that is terrible that it's that low once warmed up! With newer engines supposedly with such tighter tolerances, i find it hard to believe that GM was ok with that low of an oil pressure. But obviously it doesn't negatively effect these engines because look at how long they are lasting!!!

It has been said on here multiple times that our TB's oil pressure gauge isn't an accurate reading of the oil pressure and that the ecm just calculates certain factors and then shows a calculated guesstimate for oil pressure. Does anyone know why GM did that? Has anyone put an actual oil...

I just bought a new battery and installed it so hopefully that fixes the slow starting. And yes, it's the power steering that whines when extremely cold. I've done car maintenance since the early 90s so i am sure that's what it is. I just wasn't sure if others notice it when extremely cold too...

i noticed yesterday for my cold drive to town that my power steering had a noticeable whine to it. It was 0 degrees F and it was quite loud for a few seconds upon startup and then i could hear it with higher rpm's all the way to town and back which is 8 miles away. I've never had a vehicle that...
