If I were you I would start by replacing the biggest (Capacitors) value ones first. You could put an ohm meter on any to see if they charge up when you take them out of the circuit.

What makes my 2001 chevy silverado airconditioning make a hissing sound when my air is on

Check the bearing in the end of the blower motor. They go bad and make a noise and over time will start rubbing and squealing like crazy.

How can I reduce white noise / hissing I'm getting over the mic on a Behringer Xenyx 1204 USB setup?

Hi, you didn't say if the mic actually passes sound? The C-1 is a condenser Mic & needs phantom power - switch on the rear of your mixer. If that's no help, what happens if you disconnect the mic, then turn the levels back up? Still hissing or gone? If it's gone then it's the Mic - must use a 3 wire cable, preferably XLR so it gets the phantom power. If the hiss is still there without the Mic then sounds like the mixer is faulty - try some of the other channels..... How loau is the hiss - just in the background or as load as a vocal "one, two" test? A few things to check anyway...... Good Luck!

Air intake noise when I turn it on.?

Describe the noise.Is it a hiss,like something isn't connected tightly?Or is it a horn sound? IF it's a horn sound,it could be coming from a component right at the rear of the engine. I replaced one on my boy's Crown Vic.It's hard to do without having some good selections of 1/4"drives or small wrenches.
That sound got so bad that people were getting mad at Justin because they thought he was sounding his horn at them.
I don't remember the name of the component,but it cost me 50 bucks at Auto-Zone. don-ohio (:^D

Poping noise tv went off no picture.

Usually that popping sound is a capacitor blowing up. There are 2 ways to fix this. 1) replace the cap by itself or 2) replace the whole board with the bad cap. If you are handy with electronics and a soldering iron, replacing a cap is pretty cheap. The hard part is finding one. The local Shack may have one but probably not. If you are not comfortable taking the TV apart, then you need to find a tech to service your TV. Most techs are going to replace the whole board.

How can i get rid of the hiss and popping from my amp

A relatively quiet "hiss" is normal and is due to the statistical properties in electronics. If the level is noticeable during normal program play, then it needs to be dealt with.

First thing is to verify the noise is still there with NOTHING plugged into the input jacks. Many times the noise comes from bad cables and guitars that have noisy on-board electronics, so we must check this out by unplugging all inputs.

MAKE SURE any other devices connected to this that require connections to the power input ALL are plugged into the same receptacle.

Engine noise after parking under the sun!!

Sounds like the tank isn't venting properly. Next time you hear the hiss, try opening the gas cap. If that makes it stop, it should also drop the idle speed. If so, you need to pull the tank and make sure the tank vent hose isn't pinched.

This is normal operation, every 8 to 10 hours the heater in your freezer section turns on to defrost ice and frost from evaporator coil, this melting water hitting the heater is what is making popping and hissing noises.

Hissing popping sound

It sounds like the flyback or the HV splitter those are the two items that will hiss. It should be coming from the area where the flyback is. thats a large transformer with a large red wire coming out of it going into a Splitter that will have 3 additional large red wires each going to the three CRts. Let me know if you need the part numbers and where to get the parts with free tech support so you can easially install them yourself.
