zetabird Posted October 20, 2015 Share Posted October 20, 2015 was trying to figure out why my heat didnt work, i traced it to the vacuum line on the heater control valve. the line is melted and broke i tried to find the other half under the coolent tank but its ran into some check valve and then into a red vacuum line so something is not right here. dose anyone have the diagram or pictures of this side of the vac system all i can find are of the airbox side Link to comment Share on other sites More sharing options...
