SOURCE: 98 chevy astro battery or alternator

Well, just for electrical basics coverage, the alt puts out volts and amps and it is possible for it to put out enough volts but not enough amps.

Best thing to do is to take the alt off and have it checked to see if it's putting out enough volts and amps.

If it is, then maybe the battery is shorted out and is drawing too much off the alt to allow it to run the vehicle.

I hope this helps

SOURCE: erratic control panel

This is the solution if your car sometimes has unexplained water on the passengers side floor after it rains and the Blower is working erratic.The solution lies under the large black bezel/cover below your windshield wipers. Under this bezel on the passengers side is a piece of weather stripping that has fallen off. You will see it right away. If you fix this and replace your blower motor and resistor your HVAC will work correctly again. I spent a year trying to figure this out.

Just remove the bezel and check the weather strip. You will be able to see where it was by the discoloration. It falls off by poor design and allows water to seep into your blower motor shorting out the resistor and if left unchecked will smoke the blower motor also. You want to add some silicon sealant and replace the weather strip to it's original position.
As far as the blower motor and resistor it is not all that difficult to replace. You will have to lie on your back on the passengers side to get at it. It's very uncomfortable.

Good Luck !!!

SOURCE: 2004 z71 180000 miles. drove

if battery and alternator are good. i would check the wire from alternator to battery, they sometimes have a fusable link in the wire, that burns out. also check fuse box there may be a fuse and it may be blown! at battery with car running should be at least, 14 to 14.2. at battery when car is off should be about 12.8 to 13 volts. have a good day !!

SOURCE: my 95 tahoe has an occasional ticking noise, loss of oil pressure at idle and loss of power

Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.

Hissing noise when i press the brakes sounds like air,but when i take my foot off the noise stops


sounds like its the power brake booster that is causing this noise. you don`t say what year make model of car. ford at one time had this problem but it did not affect braking. on other cars it was the vacume shut off switch for the cruise control at the brake pedal which indicated a bad switch and needs replacing.

My 2007 Chevy Silverado loses power when I come to a complete stop no engine lights appear but if I turn off the truck the problem goes away for awhile .


Loss of power, but no mention of rough or inability to idle (including stalling). If those additional symptoms are part of the problem, check for a vacuum leak to the intake. Listen for hissing or sucking noises near air hoses. Look for loose, cracked, or broken air hose connections. Check PCV valve...Cheap to replace, could be sticking, then loosen after truck sitting with engine off. A vacuum leak will not give any light indications, and vehicle will seem to run normal when applying gas, but will want to stall or run rough (or want to stall) when at idle or sometimes when taking foot off gas when slowing down.

Hissing from exhaust and loss of power, especially when towing


You didn't give the year make and model, so I will give a generic answer.
A hissing noise from the exhaust is from a leak, and if you have a loss of power you could have a restriction in the exhaust such as the muffler or catalytic converter.

If it seems to have a loss of power you may have a clogged exhaust, (muffler) system, again if you have a loss of power or it runs ruff check for a vacuum leak.

2008 impala a/c blows cold when driving but hot when idle


Sounds like your low on refrigerant maybe.

You could also have a blender/vacuum actuated flap issue. Especially if you hear a faint hissing noise inside the car. Indicating a vacuum leak.

Try setting the AC on a different zone and see if the symptoms change...

When coming to stop car dies out. It's automatic and already cleaned mass airflow - could it be posible i need a bigger battery?


No, As long as you're vehicle starts and runs fine with some options being ran off of the battery, you're battery is not the issue, It sounds like a vaccum leak or a fuel delivery issue. Run Some Premium gas in it with fuel system treatment "Cleaner" and see if in a couple of days it gets better. If not you most likely have a vaccum leak, listen for a hissing noise under the hood of you're vehicle while it is running, if you hear a hissing noise than liik for little black hoses that will have a hole, tear or that have just come apart from where they are suppost to be.

2002 Mitsubishi Galant ''hissing noise''


I would first try to locate the source of the hissing. Try spraying some engine starting fluid around the hissing area and home in on the source. The engine revs will change as the starting fluid is drawn into the engine. Sounds though more like a vacuum as you have suggested.

Ac problem


Hissing noise likely is a failed vacuum "motor' that controls the blend door. You can locate it by putting a length of hose in your ear and using the other end as a directional probe. Follow the sound and you will find it...Reaching it to replace is another story...may need a manual to remove.
