2004 Bonneville SLE. Driver door power windows switch assembly. All of a sudden, no window, lock power to passenger door or window, and both rear doors or windows. Driver's door and window work fine.
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 .
I need the firing order diagram for a 2007 Pontiac grand prix with a 3.8 motor
the coil pack you removed them and now firing order was lost
the answer is really just the coil pack
can I assume you know all cylinders numbers,
if not that is 2 questions. plugs to pack wiring both
ahhhh the ,3.8L has 3 twin coil packs.
the packs can not be labeled because all 3 are the same paCK
I WENT ON LINE TO SERVICE MANUAL THIS CAR
AND SEE THIS
1987 Pontiac Fiero GT - Looking to why my check engine comes on and goes off while driving and my oil gauge flutters and engine almost cuts off while stopping?
Hi Jeff Dube, that is called the engine wants to stall, i nearly does
and RPM engine is super low (out of spec)
and slow engine can have too low oil pressure;. 800 rpm is the lowest speed RPM allowed (usa epa laws but no engine told)
that is called misfire.
and no OBD2 scan tool on earth works on any
1987 OBD1 car ever.
so scanning it at home is not possible or crazy expensive.
cause are up to 50s.
folks love to convert Fiero to EV battery only propelled,. I would.
2 engines uses. 2.5L and 2.8L
the cars VIN decoded online tells what engine is there, learn that and tell that for 10x better and more accurate answers.
not told when car ran perfect last?
never by you?
last month, year ,decade??
ever give it a tune up, all filters
new spark plugs, Hv wire set,cap and rotor?
so spark is good> cant burn fuel fully lacking good strong spark.
now FUEL
a car like this, this old can have bad fuel.
or had it and never cured, after.
bad FPR, fuel pressure regulator is common for sure this old
clogged or leaking tips INjectors x4
the ECU controls RPM hot.
if RPM is too low that ECU not the fault
it is other reasons many.
the 2.5L has TB throttle body with
IAC valve on this side that is gummed up.
all are that old. really.
the 2.5L not having 4 manifold injectors
has throttle body injection system
like below.
red circle is IAC< it most not gum up or ECU can not ever control idle speeds. (even with perfect spark and fresh fuel)
I have dtc po120,po220,p1516 and
This errod codes refer to Powertrain: P0-P3:
- P0XXX: Generic DTCs
- P1XXX: Manufacturer Specific DTCs
- P2XXX: Generic DTCs
- P3XXX: Generic DTCs and Manufacturer Specific DTCs
P0120
Throttle/Pedal Position Sensor/Switch A Circuit Malfunction
P0220
Throttle/Pedal Position Sensor/Switch B Circuit Malfunction
P1516
Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance
P2101
Throttle Actuator "A" Control Motor Circuit Range/Performance
Took the Throttle body off, cleaned it (looks like new!!) real good and
then I checked the Module on the side of it for moisture and the
connection!!! Put every thing back together,and so far every thing is
good ( no check engine light- no Reduced Engine Power mode.
I hope helps with this.
Engine Seized up on a 2006 Pontiac G6
check the oil and coolant levels. if coolant is low pull the sparkplugs and try to turn the engine over if still not turning free remove the serpentine belt and try again, if it turns over ok check the pullyes on the front of the motor to see if they all turn free by hand. a serpentine belt can prevent an engine from turning over if a tensioner, idler, water pump, alternator, or power steering pump is siezed up or starting to seize. being your battery is bad I'm thinking probably the alternator is seized. hope this helps mike.
