    Just wanna double check which vacuum hose goes where...

    Theres 2 hoses, one black, one yellow... Both run to black pipes. The black one I have ends up connecting to the black pipe that runs to the heater valve.. is this correct? And the yellow one runs to the black tube that runs across towards the passenger side in the engine bay?

    Is this correct or do I have them the wrong way around?!

    Cheers in advance for any help people :)

    When I asked an Auto sparky about the 2 vac lines he said that one way the a/c blows cold air - connect it the other way and it dont work. So I said I cant get it wrong - he replied not if you want cold air - if it blows hot air swap them around.

    It blew cold air so I guessed it correct. - lucky.

    I'll try and look tonight.
