I have a 96 chevy tahoe that will not lock the doors unless I use the keychain remote or puch each lock down, same with unlocking. The lock button on both the driveside and passenger side do not work. Also my rear hatch button does not work either on the remote or on the button on the dash. When pressing the rear hatch remote button I hear a clicking sound from behind the dash. Both problems started at the same time. Could it be a fuse? I was driving on a very dusty road prior to the problem.
Hello Scullen27,
While I vigorously recommend owners wanting to work on their own vehicles should purchase the FACTORY WORKSHOP MANUALS... for one time little jobs there are a FEW good alternatives... that ae also FREE.
BBB Industries maintains an very excellent technical database
for popular USA market vehicles:
TECHNICAL SERVICE BULLETINS
and Circuit wiring diagrams
(registration is required... as these are real documents)
A fuse would seem to be indicated ... if your
control is sound a relay operation... but the
REAR-HATCH is not cooperating... THAT WOULD
be the place to start,
Hope this helps...

With regards to the lock bittons on the driver and passenger side its the button themselves aka switch(s) that is your culprit. Why because the remote is getting the motor to open and close them . The only thing that doesn't is the buttons /switches themselves .
Now the rear latch a little different animal. Either the locking mechanism on the door itself is defective or the motor ( the thing you hear clicking) is weak.
This one your gonna need a shop manual for to do the correct testing.But being that te remote will not move it and neither will the manual push button I would lean towards the locking mechanism on the hatch/door its self. Use the shop manual its not that bad of a fix if you have a little patience.
