Question about 2002 Chevrolet TrailBlazer

Open Question

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.

My toyota kluger Grande 2009 alarm goes off randomly... Usually after using the rear glass hatch. I close the glass hatch, Remote lock it and within a couple of hours the alarm is going off.


If there are any insects or such the motion detector in your car may be detecting them. Your opening and closing of the hatch may be letting something in??

VW Beetle Alarm goes off for no apparent reason


the sensitivity on the alarm itself is too high, or there is something around the car that is interfering with the frequencies that are sent / received by the alarm itself, like other car alarms, power lines (mine actually did it when i parked under a power line) or the alarm unit itself is malfunctioning.


make sure that nothing is around to the (other cars with alarms) or look up under your dash, above your pedals (might have to take the trim plate off) and / or turn the sensitivity knob (flat-head screw driver, or just a simple protruding knob) down. make sure the battery in the remote is good too. if it stil ldoes it after this, then your remote needs to be reprogrammed.

Broke the remote now the alarm goes off when you unlock the door


Unlocking the hatch or drivers door will turn the alarm off yes.

If the key took a beating then you probably need to have it replaced

2000 VW Beetle Hatch won't close tightly.


Try taking the battery out of your remote to see if it just still sending the signal????? You might have to clean your remote with contact cleaner. Also check the latch to make sure nothing is in the way of the latch????
