When you put your A/C on, there is Vacum Motor or Solonoide, that increases RPM of the Engine to compensate the load of an A/C. If the vacum hose is leaking or raptured the RPM of Engine remain low and Engine Shakes. When you put the A/C on and the RPM of Engine Increases, but a little, then your Selonoide is working but not adjusted properly, so adjust it for the proper RPM of the Engine. Put all the loads on, I mean Head Lights and A/C on and then ajust the RPM.

95 NISSAN ALTIMA TURNS OVER WONT START AIR FILTER SMOKING


Its probably back-firing in the intake - which means it is firing early or the fuel mixture is very lean.
This engine uses a distributor cap and rotor, so I would start there and make sure the cylinders are firing correctly.
If the ignition checks out ok, it could be a problem with the cam timing.

2003 Nissan Xterra - Fan noise when a/c on


No that doesn't sound like the problem, the fan clutch locks up to cool the engine off due to the increased load of the AC system on the cooling system, so it locks up and gets much louder. If it didn't lock up the engine would overheat.

When car picks up speed the heat blows. when u stop or slow down. cold air blows


Tell me when you speed up is the heater set on hot and high speed?????
WHEN you slow down is the fan still going at the same speed or dose it go very slow when on idle.
If the Fan stays on high but runs cold when going about 80 in top but when you speed up it gets hot and then back off slightly then its sounds like Water pump isent pumping the water around the engine correctly ,but then it should make the engine run overheated.or it could be a slipping fanbelt, but then that should make the Alternator to make a noise,so {throttle to 2000 rpm from idle standind still} and see if there's a noise coming from the water pump area.
The belt should have just a little free movement more on the longest part of the belt(a very little about 1/8' movement
So check it out and let ne know how you get on .

My 2003 Nissan Altima makes a waired raddaling noise only when i turn on my air condition or defrost on. What is it that i need to fix. I'm guessing my cooling system needs to be flushed or it's something...


sounds like the clutch on the compressor to me and they are not sold seperatly so you are looking at about $600, sorry to be the one with bad news.

I have an 03 nissan altima engine makes loud clicking noise


1st check the the oil level and the vehicle's oil type.(owners manuel) 5w30-10w30
10w 30 is a thicker oil and could possibly be causing this.(Moves more freely through the engine heats the oil)
