2002 4.5 liter s-10 pick up wont go in 4hi. 4 wheel drive push button on the dash. Put truck in neutral and it will go in 4 lo. Vacuum actuator under battery tray is working when button is pushed. Can hear actuator on transfer case clicking when button is pushed for 4 lo but does nothing for 4 hi. Disconnect the battery and truck will go into 4 hi, 4 lo, everything works fine for awhile then back to not working! Installed another module behind kick panel from junk yard, with no diff results execpt everything works fine for awhile like disconneting battery. Any hep would be appreciated. Thanks in advance!
