2004 GMC Sierra Questions & Answers
GMC 2004 Sierra conditioner makes Darth Vader noises
I'm not sure if I understand you correctly. Does the air conditioning works properly it's just the sound problem and did it happens suddenly?
For the strange sound, it could be normal and not.
I imagine the sound comes from the exchange pressure between the low pressure and high pressure.
To fix or knowing what is wrong you will have to get AC/pressure gauge install on AC/pressure tap under the hood and sync the compressor engaging clutch if it happens at the same time that the sound you are talking about.
Pretty hard to tell online without earing it. But I ever listen to a sound similar to that.
hope it helps
04' GMC Sierra quadrasteer, trec fuse 30a blows when trying to engage 4wd. I replace fuse, start truck and 4wd auto is lit up but if I press 2h, 4h, or 4 low it blows. What should I do or look for?
Wild guess here, had a similar problem on my 2000 4x4 blazer, has an electric motor on transfure case to swith it into 2h, 4h, and 4l, would blow the fuse every time when switching, did is to replace the motor. Just confirm your fuse that is blowing feeds that.
How do you prime a oil pump in a 6.2 gas motor in a 04 gmc pkup
Hello Les, I suggest you install an auxiliary oil pressure gauge to measure the actual oil pressure. Did you inspect the oil pick up tube screen for debris that might restrict the oil from getting to the oil pump? Did you install an oil pump mounting gasket or o-ring if it requires one?
