2004 Pontiac Grand Am - Answered Questions & Fixed issues

Seems that the IPC/BFC ACC fuse is responsible for the instrument gauges not working on your 2004 Pontiac Grand Am 3.8 Liter1. It is possible that the fuse is faulty and needs to be replaced. However, if the fuse is in good condition, there might be an issue with the wiring or the instrument cluster itself. Check the inputs (powers and grounds) going into the cluster with the key on using a voltmeter. Fix/repair wiring as needed or replace the instrument cluster as needed. A qualified mechanic might diagnose this --and a scan tool.

Check the stater fuse and relay

Question edited for clarity. Question moved to model category. Jeff, our Pro Auto Tech and Electronics Wizard gives the best answer. Jeff Armer Nov 27, 2022 injector pressure sensor ???? It doesn't have anything like that, it has a fuel pressure regulator - vacuum operated . Hook up a scan tool and check for codes or take it to a qualified repair shop. Quit trying to play auto mechanic.

How are you 'locking it' to make the noise? clock spring connection and is a known issue. https://www.google.com/search?q=2004+pontiac+grand+am+horn+not+working What does 'cruise control' have to do with the horn not working? ..

Hope help with this (remember rated and comment this).

Hello! To check the fluid level, the first thing you want to do is get the fluid to operating temperature, by driving it for a bit and letting it shift through all gears. Once you've done that you need to make sure you park the car on a very level surface. Remove the front passenger wheel and the splash guard. From there reference the picture below to give you an idea where the fluid check plug is located - there is no dipstick on this transmission (4T45e). You will also see the fill plug location.


If you do a pan drop and filter replacement only, the fill capacity is 6.9 quarts. You will want to use Dexron III type transmission fluid.

FYI - here are the torque specs for the pan bolts is 106 in/lbs and the check/fill plugs are both 124 in/lbs.

Hope this helps and good luck!

1. Defective wiring 2. Defective socket

Tail lights, if both of them are out more than likely that's going to be a fuse. Dash lights possibly have a fuse of the thier own also but I would think they would work off your headlight fuse so you might have a separate issue there but always check the dial that increases the light just in case it got lowered somehow.

Unfortunately you are correct, this
vehicle has the PASSLOCK II key
based engine disabling system, and currently it
is engaged. The sensor does not recognize &
retain the passlock reader chip in your ignition
switch any longer.

A bypass is required to circumvent.
If left unchecked, it will lock down the fuel injector
rail (as it has now), and you will need to
tow it in to GM for evaluation, and resetting.
Eventuall, the 10 minute over ride will cease to
work and you will finally be forced to visit
a Pontiac/GM dealer.

But, if you want to just remove this system
from the equation entirelly,
I suggest the PLJX bypass kit to get around
this issue.

This Passlock Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.

The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the passlock system.

That is it's designed purpose.

However, in your case, this input wire on the PLJX module,
instead of going to a momentary ground pulse from
an alarm/remote starter,
would go to a constant chassis ground, through
the bypass module, grounding out the PASSLOCK.
The PASSLOCK would then always be bypassed as long
as that wire is chassis grounded.

I can not speak about a damaged passlock system,
like if a thief has destroyed it, because I do not
get into this part of GM'S security application.
Coincidence to installing
after market remote starters, this does work on bypassing
passlock in most all GM vehicles,
including your year GM vehicle as well.

Also, this is a self learning, resistor sensing
and adjusting module. Once the VATS wires have been tapped,
you would press the program button to learn,
and it does. The car should then allow start
with any hardware store key.

There are no adjustments you can make . Idle is controlled by the PCM - engine computer via the IAC - idle air control valve. Changing the fuel pressure regulator shouldn't have changed the idle at all . So , what did you do wrong .

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few .. let me know if u need help thanks

If equipped with an anti theft system it may be malfunctioning or have a bad sensor . The horn switch or relay may be bad also .

DID YOU FAIL TO HOOK UP A WIRE OR MYBE BAD FUSE

I know this website www.reliable-store.com that i get manuals from, and they have all models online that solve all simple/technical problems like professionals I also brought for my 1989 BMW, such old model, they had it and it was very good manual. Go ahead, I bet.

One possibility is the temp sensor,if it does know it's a cold start ,it won't have an enriched fuel mixture to start. Change it or put on a scanner and look at the temp sensor reading when cold.

No, but the relay could be shorted.

For DIY, try to replace the switch 2. Locate the flasher unit and see if the noises coming from there.

This sounds like a worn out cv joint. You should have a qualified mechanic check it out. It is impossible to say for sure what it is without checking it.

Replace the turn signal switch
