Another 4wd Issue
 

New member here. A month ago I purchase a 1995 blazer the owner told me the it need a new transfer case but after reading about the TC issue I found one of the vacuum lines had a had a hole on it to be specific the one sitting next to the transmission dipstick and after that I went ahead and check the actuator under the battery tray and yet another vacuum line disconnected.
After putting everything back together I went for test drive but only 4lo is working but not 4hi but after I came back From the test drive I found my self with another issue while I was trying to park the truck (4wd disengage) it felt like the front wheel where lock and my 4wd switch only light up when I press 2hi or 4lo but nothing went I press 4hi.
I really need some help ASAP
