Hi,
You may want to check that your AC compressor is not trying to seize up. If so the problem with soon destroy the belt.
Good Luck !!!!!!!

I have a Nissan quest 2004 model, the engine is not making much power like before when I turn on the AC it's be comes more slower and annoying.


Your AC is powered directly from the engine by a belt. Turning the AC on makes the engine work harder, draining power to the rest of the system. With an engine working properly you wouldn't normally notice it.
Do you have any warning lights on the dashboard that were not there before? If yes, What do they look like and what colour are they?
It would be a good idea to get a good mechanic to find out why the power has dropped on the engine. A loss of power could be down to either a simple sensor problem or something much more serious.

My impala runs great but when i go to leave and stop at a light and shes in drive sitting at the light she makes noise like loss of power or stalling idk i went to aotuzone they checked my alternator its...


When the AC is turned on, a number of things happen: the cooling fan is engaged, the idle speed is increased to account for the additional load of the compressor, and the AC clutch is engaged. My guess is that what you are hearing is the AC Clutch rattling due to a worn input shaft bearing. As soon as it is engaged, the noise goes away. It is possible that something else is going on here, but I would be tempted to focus on the AC compressor as the SOUND portion of your problem. When you say "...she makes noise like loss of power or stalling, I am not sure what you mean. Is it a noise, or is it actually losing power. With no MIL (check engine) light on and if the noise goes away after servicing the compressor, I would say you are fixed up. Good Luck.

Loss of engine power, loud whistling noise


Exhaust manifold leak? That's not common. You talking about the VVT near the manifold at the top of engine above the power steering pump? Yes indeed, AC Delco is the only one our engines love. 41-103. Obviously you have P0304, what other codes?

My battery drains every time I turn the ac on and when I turn it off I charges , there is also a whining noise in the engine thank u


My thoughts is your alternator is going out, but check your belts are not loss or frayed which attach to your alternator first. if your belts seem fine, remove your alternator and have it checked out as it should be producing enough power to keep your battery charged.

Repair orepair a/c on 2000 sierra p/u


have you checked the pressure of the refridgerant 134a in it to see thats its at the right prssure because that will kick the ac out if it is too low also have you heard any rattling noises in the engine compartment if so might want to make sure the ac clutch is operating normally because if it is losse and rattling it will lock up the compressor eventually so it might need that to be fixed to make the ac work right

Flashing oil light/ loss of power


Check your converter on your exhaust when it's running and see if the noise of rattling is coming from there.If it is you have a plugged converter,it's broken up and in piece's which will make noise and no power especially when calling for power.Be sure to let exhaust cool before repair is done.If the engine is making the noise like a knocking sound you should bring it to have it checked.Hope this help's.
