When I first turn on my A/C is seems to be cold for a second and then it gets hot again. i was told by the previous owner that the a/c was not working but that he had it fixed. One other element in the equation. When driving with the a/c set to on(ie not idling) the car makes a funny noice around 2500-3000 rpm in all gears. what ever this noise is, it is directly related to the to the engine. the car will jolt slighty with i reach aroung 2500 rpm and make a sound that reminds me of a hose letting out air pressure.
please help and doing kill me because i dont know much about cars just yet. But i am learning.
