Rear trunk latch quit on my 2003 Trailblazer
Help,
The rear electrical trunk latch stopped working. I did not see a dedicated fuse in the manual. If I hook a VOM to the elec. contacts and press the unlock keypad and get a voltage spike it would mean that the selenoid is bad. If no voltage the wires are bad. Correct? |

not that simple
This is general response not specific to that model.
If you get a 12 volt pulse at the wiring connector at the solenoid it is likely the solenoid is bad. Verify this by connecting an ohmmeter to the solenoid. If you get no reading through the solenoid (coil) that would confirm a bad solenoid. If you do not get a 12 volt pulse at the solenoid wire connector there are a number of things that could be wrong. This is likely a computer controlled device that is disabled under certain conditions. For example: car in gear, trunk lid open (bad switch) or security system activated etc. The circuit is fused and could be combined with some other devices like power door locks.Testing the fuses requires a test light or meter. A shop manual will help. ALLDATAdiy.com Leading Source of Factory Automotive Repair Information Wires very rarely go bad but the connections do. vicrod |
