I have noticed the last few months that when my air conditioner is blowing and i accelerate, the air quits blowing out of the vents and then returns after i reach normal speed. It happens on fresh air and recirculation settings. Has anyone got any suggestions?

First suggestion is, what vehicle is it? Sounds like a vacuum problem When it quits blowing is it really blowing out the defrosters?

Vacuum leak. Possibilities include the cruise control mechanism underneath the battery (battery acid drips and erodes the vacuum line going to the canister, causing a vacuum leak), or a leaking intake plenum gasket. If you remove the PCV valve, and can feel a vacuum when covering it with your thumb (especially when revving the engine), then you have a plenum gasket leak, and will need to remove the intake manifold to repair it.
I checked the PCV valve vacuum and there is none. I also tried revving up the engine and the air cond worked ok and I revved up the engine with it in gear and still ok, but when I drive it, it does is almost immediately. Only for 10 seconds or so. It's not really a big problem but just kinda irritating and hoped it would be simple. I am going to take out the battery and batt holder and check the hoses. I found the canister (I think) under the driver side door with 3 hoses. 1 large one secured good, and 2 smaller ones and one of the smaller ones came out of the boot easily. I'll try and seal it better and try again soon.
