2004 Pontiac Bonneville - Answered Questions & Fixed issues

You probably have no idea how these work - power locks an power windows. Control modules inside each door make them work . Power Windows Operation The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA. When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested. When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor. Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing. Hook up a scan tool an check for DTC'S could save time in diagnosing this . Also on a vehicle that old checking for broken wires in the door flexes would be good to do. Opening an closing the doors a million times causing wires to stretch ,break et... The power windows on your vehicle has a circuit breaker for battery power ,not a fuse. The power locks do have a fuse for power. Won't think circuit breaker an fuse bad at same time .

Check out the link. It is hidden in the air filter. Are you going to remove it, reprogram it, what's up? https://www.google.com/search?q=2004+pontiac+bonneville+sle+ecu+location ..

Feel free to use any Pontiac Grand Am car stereo wiring diagram that is ... wire colors and diagrams before applying any information found here to your ... you the diagram or schematic you need for your mobile audio installation. .... I have a factory stereo in my 2004 Grand Am. Neither of the back speakers work anymore?

See this Video: https://www.carcarekiosk.com/video/2004_Pontiac_Bonneville_SE_3.8L_V6/lights/headlight Hope it helps.

You first must gain access to the bulbs. Then remove them. They should have a number on them allowing you to Google them and locate a source for new ones. Last, reinstall the new ones and then reinstall the radio/dashboard.

probably not the plugs if they look good but more likely a problem injectors which is the case in most misfires

Sounds like you have an air pocket in your cooling system. Could be caused by leak or head gasket failure. I recommend letting a shop diagnose before some serious damage happens

Why ? Does the blower work on high ? but no other speeds ! If it doesn't come on at any speed it's not the resistor . Does the vehicle have automatic climate control or manual ? Automatic doesn't have resistor , has a blower motor control processor . HVAC Blower Motor Circuit You need to test , not guess !

disconnect a wire to the chime cables that no longer in production can be made in a reputable brake shop from the sample there are cable makers in industry that make cables to samples so find a cable /chain retailer and take the sample to them it seems strange that a 3 year old car does not have spares still available so I would be checking around spares departments or brake repairs shop as well

4.8? that didn't exist for a '04 bonneville Buick 3.8L engine - 1-6-5-4-3-2 Cadillac 4.6L Northstar engine - 1-2-7-3-4-5-6-8 The cadillac motor was only in the GXP package

passenger side under the glove box , Remove the right side sound insulator. Refer to Instrument Panel Insulator Panel Replacement - Right Side in Instrument Panel, Gages and Console. Disconnect the electrical connector (1) from the blower motor. Disconnect the blower ventilation tube (2) from the module. Remove the blower motor screws (3). Remove the blower motor from the housing. Instrument Panel Insulator Panel Replacement - Right Side Removal Procedure Remove the fasteners at the rear edge of the insulators in order to disengage from the lower instrument panel. Pry out the retainers in order to release. Turn the heater temperature sensor 1/4 turn in order to release and allow to remain connected to its wire (CJ2 vehicles only). Disconnect the electrical connectors. Slide the insulator rearward in order to remove.

Remove the O2 sensor on the back side of the engine exhaust manifold. Start it, if it runs for more than the 2 or 3 minutes, replace the catalytic converter. 455 is a purge solenoid code. This wouldn't keep the car from running.

#1 Bad coil #2 bad module #3 could be bad wire,Any Codes?

Check coils,module,wires,any codes?

most people who do not do the first step generally go crazy chasing the problem the first step is to have the fault codes read as they are there as a diagnostic tool to stop people from going crazy

Fuel Pressure regulator ..maybe Turn the Key to the 'ON' position, the fuel pump should run for about 1 second. listen for it. Do this a few times without trying to start the car. This should pressurize the system. now try starting the car. There may be air in the system from changing the filter.

Walt, You will hear the fuel pump at times. When you take the gas cap off the fuel tank is acting somewhat as an echo chamber that is amplifying the noise of the fuel pump. Presumably the engine is ticking over when you remove the gas cap? Otherwise the fuel pump should not be running. The fuel pump only supplies fuel on demand - obviously. The pump will run to pressurise the system to meet demand and if that demand for fuel fluctuates, the pump will run down or increase speed accordingly. This speeding up and running down of the pump is constant. If by 'a miss' you mean that the fuel pump goes quiet for a second or so - that's normal. No demand for fuel - the pump doesn't run. That wouldn't effect the engine at tickover. If the 'miss' is from the engine at tickover that's more than likely to be a plug. If your car runs okay at speed and doesn't cut out and then will restart almost immediately, it sounds as though your fuel pump is okay.

Mass airflow sensor ? Is the check engine light lit ? What engine - 3.8 or 4.6 ? TPS - throttle postion sensor
