Could be the driveshaft.
I'm guessing it's either the driveshaft or the muffler. Need more info.
2004 Chevy Blazer has two catalytic converters. One up close to the engine just after the pipes from the exhaust manifolds come together, and one down closer to the middle of the vehicle. The first one is sort of round, and the second is more flat and wide.
My fuel filter on my 91 is located: under the middle part of the drivers side on the frame in front of the rear tire. Its a round canister looking thing attached by a hose clamp looking strap. Might be there on yours.
Underneath the passenger side rear floor, under the vehicle. It is round, cylinder shape.
Under the hood there is a black box. Open it up, there is a small black round nob on the top of it. Once it's open, follow the diagram to find it.
Just follow the big black round plastic intake hose coming from the air filter box and going to the engine. It will clamp onto the throttle body housing.
Underneath the stearing column there is a fuse box behind the break pedal. In that fuse box there is a round silver thing pluged into it. That thing is the turn signal switch. Just take it to what ever auto store you go to and tell them the make and year and all that stuff, and they will get you what you need. It just plugs in the way it came out.
My blazer is a 4.3Tbi; the fuel filter is in the frame rail on drivers side. about half way point of truck. climb under truck look up into frame U cant miss the round shiny thing. You will need 2 wrenches as not to harm fuel lines,
No, the full size Ford Bronco tire carrier is fitted to the round body parts on the right rear of the vehicle. Also it has a support bracket that the swing arm clips into that is bolted into the rear gate. It will not just bolt up to the chevy.
in my 99 you have to take the whole door panel off. Just unscrew the door handle on the inside and the little round tab where the door meets the car.
"Round Eyes in the Middle Kingdom" is a book written by Robert Elegant and was published in 1978.
The flasher unit for both the turn signals and the emergency lights are under the dash, between the center console and the storage area. It's not hard to get to, just takes some time and patience.
