2002 trailblazer alarm acts up.. is there a fuse or reset?

Hey one day the alarm was not on, but i closed the hatch and the alarm started to go off.. turned it off by the remote and it turned off... went to start it a little while later and it wouldnt start and said unknown driver.. had to climb through and slam the hatch to get it to work... now after that happened... only the drivers window will roll down and lock, but no other windows or locks.. and sometimes if the passenger door is closed hard enough the truck locks down and says unkonw driver.. any suggestions or thoughts... i was hoping someone would be able to tell me where the relay is from the alarm to the doors... or the fuse/reset... thanks

SOURCE: no power to passenger door window or lock, drivers

I know this sounds strange but I believe the problem is in the drivers door. This is where the master switch is and controls the other doors. Have it tested or replaced. Hope this helps. Good luck.

SOURCE: power door locks and windows not working from the drivers side

Check the fuses first. If that dont work take the door apart the wiers have problably lost the connection due to kids and chocolate.
Gotta love them tho.

SOURCE: Driver and Passenger auto door locks are inop.

Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.

SOURCE: 2005 colorado pulled fuse for power locks, to stop

This is a common problem, there is either a pinched wire in the harness that is in the door jam or your fuse block is shot, there is a gm service bulletin out on this, I would call your local dealership to find out if it is covered.

SOURCE: door locks and power window

Just did this procedure I got from coloradofans.com forums:

"any type of power/voltage change seems to trigger this issue

The most common symptom is power locks fail and only the driver window quits, however that is on the extended cab.

Steps to fix and it works every time.

take door panel off driver's door
Disconnect the wiring attached to window and power lock control unit
disconnect battery cables
connect the negative to the positive cable(((NO BATTERY CONNECTED)))
This will act to short residual voltage in the system

5 minutes later
place the key in the ignition and turn to the run position
connect the wiring to the window/lock controller
connect the negative cable to the battery
then the positive
open drivers side door
turn key to the off position((do not remove yet)) you should get a series of dings through speakers telling you the key is still in the ignition
once it begins dinging pull the key out and you should hear the door lock solenoids trigger and the windows should work." - Coloradofans.com forums

My trunk/hatch release will not work on my trailblazer also liscn plate light


There should be a fuse also do you have a key fob. With rear hatch button on does that work if not check fuses for the body controller. Also check for power and grounds at rear hatch motor/actuator .
Good luck Steve

I have a seperate remote start/alarm by viper and it's been acting up lately. So I had to use both remotes to unlock my car but got the back hatch open. It does still act up and seems like it's sticking. I'm going to try and give it a shot of wd-40 and see if that helps at all? If not then I don't know what to do? Maybe get rid of it then?
