Hey guys. I'm new to the forum and greatful to be here! We recently got my wife's old truck back from family farm. Her pap bought this 99 Dark green 4.0 stepside manual transmission truck new for 25 years ago. Got a Lil issue with the heater not switching from windshield to the centre dashboard ducts. I been digging around on the net and I see guys have been fixing the vacuum lines. I didn't see to much info on the 4.0 vacuum lines. Any help is very much appreciated as it freaking hot. THX
