Diff lock switch on '87 4kq
Last year, my diff locks worked as needed. Earlier this year I had to tear
apart my dash, which involved disconnecting the diff lock switch/panel. Now
my diff locks are not engaging. I'm assuming (hoping) that the problem is
with the switch/vaccuum system and not the diffs themselves. Do I have to
do something to "prime" the system since I had disconnected the vaccuum
hoses? If not, I assume I'm looking for a vaccuum leak. Is there an easy
way to diagnose?
TIA,
