Bigfoot Posted October 13, 2006 Share Posted October 13, 2006 Vaccum line from distributor to a/c unit I don't know. On a C5 there is a vaccum line that goes from the engine bay, through the firewall to the inside of the car and controls where the a/c blows and ext/internal air source. That contoler that the vaccum line goes to is under the passenger side dash...but again, that's on a C5.Good luck. Link to comment Share on other sites More sharing options...
Guest UVETTYA Posted October 13, 2006 Share Posted October 13, 2006 Wish I could help but I don't have a clue. Maybe someone has a manual? Link to comment Share on other sites More sharing options...
Donbecker Posted October 13, 2006 Share Posted October 13, 2006 I have the Haynes manual for the C4. Which vaccuum line are you talking about? It broke where? When you follow it back where does it lead to? Link to comment Share on other sites More sharing options...

It was hooked to the 3-way check valve. That also goes to the cruise. Link to comment Share on other sites More sharing options...

The C5's A/C controls run through the harness, to a checkvalve as well.If you can run power point, take a look at my A/C repair here.If you can't run power point I'll post pics if you want.
