Car Alarms: 2005 tahoe back door, chevy tahoe, door switch

Question
My 2005 chevy tahoe back door is not responding to the unlock buttons on my aftermarket alarm or truck door buttons.  I've checked the fuses and they all are ok. I can't seem to pinpoint the problem.  Can it be my alarm?

Answer
Start with unpluging the after market alarm door lock
harness. The alarm brain may have a fault in it.
Bad relay, burnt circuit board etc...,
Then see if the locks work with the door switch.
If so, the alarm as I said, has a problem.

If not, then the truck door lock module or
master fuses under the hood may need inspection.

Let me know what you discover.
