'86 XJ Heater Vacume control

[Bowman]

Hello and a good morning to all. I am requesting some assistance from the members here on the board. I have an '86 XJ, 2.5L with the 4 speed trans. I am having a problem with the vacume controls for the heater, and was wondering if any one has a good schematic of the vacume lines. I have already been through the service manual, to no avail. There is nothing in it about the roughting of the vacume lines. I am also thinking of removing the vacume bottle that is located inside the front bumper, is there a problem with doing this? Any assistance would be greatly appreciated. Thank You.

thank you for the assistance. I have removed the bottle and checked all the hoses. Now everything works with good air flow, with the exception of the defrost setting. The heater vent is still open and there is little to no air flow from the defrost. Does any one have any other suggestions?

Thank you.
