My "Gate Ajar" light is on eventhough the back
Mine was doing same thing. 03 trailblazer. Mine ended up being the 4 prong connector sensor gear was out of alignment. You have to take the entire latch out to remove the sensors. You can then rotate or realign the gear for the gate ajar switch. This was after realigning the gears.
Replacing license plate lights on Chevy Trailblazer
I just had the same problem. I took the cover off, saw the white bulb base, twisted it to take it out, but it popped back inside the door. I got it out, but it wouldn't pull through, so I twisted it back in place and went to Autozone to get new bulb. Once I saw the new bulb, it was obvious, just the bulb itself pulls out. There's so little room to work, I couldn't get it with just my fingers - - maybe rubber gloves would have worked, but I used pliers, lightly, wiggled it a little and it popped right out. I had a similar issue once with the taillight bulb and had to break the bulb and then grip the remaining filament wires with pliers to get it out, so that was my backup plan, just in case.
Hope this helps others.
2002 chevy traailblazer head gasket replacement and put it back to gether
If you are asking how to do this, it is not easy, it is very complex and takes a long time. The big points: Drain the coolant, disconnect battery, take off the intake manifold, take of the exhaust manifold, remove the head, clean the head and check for warp and cracks, clean the block and remove all debris from cylinders, install gasket, put head back on, put manifolds back on, replace coolant, change oil, connect the battery. You may have issues with bolts that break or strip out the block, you should send the head in to be checked, the valves and springs should be checked and those seals replaced, you need special tools and reference materials.
Eng. code P1484
P1484 - Cooling Fan System Performance
06-06-2005, 10:51 PMHere's what the GM Manual says about this code:
The cooling fan relay sends a pulse width modulation (PWM) signal of 12-14 volts to the cooling fan clutch through the cooling fan clutch supply voltage circuit. The powertrain control module (PCM) uses this
PWM signal in order to control the speed of the cooling fan clutch. The
signal controls the position of the oil control valve inside the cooling
fan clutch. If the cooling fan RPM is different than the PCM is
expecting, DTC P1484 will set. The actual cooling fan RPM vs the desired
cooling fan RPM is not always exactly the same. There can be up to an
The engine is running.
The system voltage is greater than 8.5 volts.
The intake air temperature (IAT) is greater than -7°C (19°F).
DTCs P1481 and P1482 are not set.
The engine speed is less than 3200 RPM.
The engine speed is not changing more than 250 RPM for 5 seconds.
Fan command is greater than 0%.
The maximum allowable error of 1000 RPM in the cooling fan speed occurs
for 100 seconds.
The PCM detects that the cooling fan clutch is locked up.
The Reduced Engine Power indicator illuminates only if the PCM detects
that the cooling fan clutch is locked up.
The PCM illuminates the malfunction indicator lamp (MIL) during the
second consecutive trip in which the diagnostic test has been run and
The PCM will store the conditions as Freeze Frame/Failure Records data.
The PCM commands the cooling fan clutch to 100%.
Follow this procedure in order to clear DTC P1484 after completing a
Use the Clear DTC Information function on the scan
Perform an ignition key cycle.
The PCM turns OFF the MIL after the third consecutive trip that the
diagnostic test has run and passed.
The history DTC will clear after 40 consecutive warm-up cycles have
occurred without a malfunction.
An inline connector could cause an intermittent DTC. Ensure to test for
poor connections and pin retention at all inline connectors. Refer to
system schematics for connector and locations.
If the condition is not present, refer to Testing for Intermittent and
Poor Connections in Wiring Systems.
Disconnect the harness connector of the cooling fan clutch from the
shroud. Inspect the exposed wires between the harness connector and the
If DTCs P1484 and P0113 are set, and the weather conditions are cold,
the cooling fan code may be false. Clear DTC P1484, and after an IAT
sensor check, allow the DTC to reset .
I'd say that 'fan clutch is faulty' is your problem, based on the information you gave. Thank you for using Fixya and good luck
