Guys, I have a problem with my Sentra recently. When I'm not accelerating, the air-cond is hot although there's still a lot of wind blowing out, when I step on the pedal the air cond will slowly become cold back.

Unfortunately just now when I drove it the same thing happened, its just that even when I accelerate the air-cond no longer becomes cold... and there's a constant noise (like air-cond type) coming from the vent in front of the car... it only disappeared a while after I stopped my car.

It's a 1.6 Sentra year 2000..

Fella N16 owners, I recently have a problem with my 2003 N16 where the gearbox will have an gear engagement delay for a second or two if it's a cold start.

It works perfectly fine if it's been "warmed up" but if you turn off the engine for perhaps an hour or a few then it will have this gearbox lag again.

When this happens and you go for the gas pedal, it will not respond for one second or two but there will be an sudden engine thrust after it starts responding. It is as if the gas pedal has registered your stepping on it but it takes two seconds to respond.

Anyone's faced this problem before and have a solution?
