Air con vacuum dramas

I have an EB 4 speed auto and after doing the CFI to MPI conversion I have had some problems with the air conditioner vents closing when the engine is under load and a vacuum noise (hiss) coming from the air con temperature slider knob when set to full cool position. I also have a question about the air con vacuum hoses. Can someone tell me where the vacuum hoses connect up to. The are 2 black and one green vacuum lines coming out of the firewall and into the engine bay.Help please.

Re: Air con vacuum dramas

i had the same problem when i had the CFI engine, hissing sound and the vents directing to windows when you plant your foot. all i did was take the climate control box (next to the instruments) thing out and played around with the vacuum hoses until it stopped making the noise. i think i just plugged up one of the vacuum hoses with blu-tack on the right side of it... can't remember which. fixed it right up and worked perfectly ever since. :)
