Mirrors are separate from the other things. Driver and Passenger Outside Mirror Operation In order to control outside rear view mirror adjustments, two switches are contained within the driver door switch assembly (DDSA). The DDSA contains a built in mirror select switch and a built in mirror position switch. The DDSA reports the switch activity to the driver door module (DDM). The mirror select switch is used to select which mirror, left or right, is to be moved. The mirror position switch is used to move the mirror that has been selected to the desired position. When the mirror position switch is activated in a Up, Down, Left, or Right direction, the DDSA recognizes the input and sends this data on to the DDM via the power door serial data circuit. Depending on which mirror has been selected for adjustment, the DDM either moves the driver door mirror to the requested position, or sends a power door serial data message to the passenger door module (PDM) indicating that the passenger door mirror needs to be moved. The PDM then moves the passenger door mirror to the requested position. Each mirror has two reversible motors for position adjustment. The door modules control the reversible motors by supplying Battery Positive Voltage (B+) and ground to these motors. Outside Mirror System Components The power outside mirror system consists of the following components: • Driver door switch assembly (DDSA) • Driver door module (DDM) • Passenger door module (PDM) • Driver outside mirror • Passenger outside mirror • Power door serial data circuit • DRV MDL 10 A fuse (door module logic and internal driver operation) • PASS MDL 10 A fuse (door module logic and internal driver operation) Power Windows Operation The vehicle is equipped with power windows controlled by the door modules. Each passenger door power window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally on its associated door. The driver door power window can only be operated from the driver door window switch built into the driver door switch assembly (DDSA). When the driver door module (DDM) receives a window switch request from the DDSA, the DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation to occur. If the status information is correct, the DDM, either supplies power and ground to its associated window motor, or, if the request is for one of the passenger windows, sends a command via the power door serial data circuit to the passenger door module (PDM, LRDM, or RRDM) controlling the window. The passenger door module (PDM, LRDM, or RRDM) controlling the window then supplies power and ground to its associated window motor to move the window as requested. When one of the local window switches mounted on one of the passenger doors is operated, the associated door module examines the request and checks to see if there are any messages from the DDM prohibiting the movement. If conditions are correct, and no prohibitive messages have been received from the DDM, the associated door module then supplies power and ground to its associated window motor to move the window as requested. The thing to do first would be to hook up a factory or some other type professional scan tool an check for DTC'S - diagnostic trouble codes. DTC B3377, B3382, B3387, B3392, B3397, B3452, B3457, B3462, B3467, B3472, B3477, B3482, B3517, or B3522 Circuit Description The switch that failed and generated this diagnostic trouble code (DTC) is part of the driver door switch assembly (DDSA). The DDSA contains a microprocessor which takes the signal generated by this switch and assigns a digital message to it. The DDSA then sends this message over a power door serial data circuit to the driver door module (DDM). Same thing for locks. The DDM must be powered and must not have DTCs B1327-Battery Low Voltage or B1328-Battery High Voltage set for this DTC to set. Your best bet might be to find a good auto electrician.

It may be the fan motor to the radiator

Lack of maintainance will lead to the piston slider seizing up and the brakes will not release, getting hotter and hotter until the brake fluid boils and causes the other side to lock on with the pressure.

Question edited for clarity. Question moved to model category. No, a BCM is plug and play. One the ECM needs programming because it contains the VIN Number and the Mileage. There are very few situations that require changing the BCM. Get is checked by an auto electrician with a pro grade scan tool computer first. https://www.google.com/search?q=1995+Pontiac+Firebird+install+new+BCM https://www.google.com/search?q=auto+electrician+near+me ..

Question edited for clarity, add maker, wrong type of 'peddle/pedal'. Question moved to model category. It has ABS Brakes, so you have to use a pressure bleed bottle that forces brake fluid from the wheel slave cylinder, through the ABS Valves and up the the master cylinder. You can't do it the 'old way'. https://www.google.com/search?q=pressure+brake+bleed+bottle ..

I saw this question hanging around since yesterday, so thought I would take a crack at it. I remembered that Jeff has access to data where grounds are, so thought I would try. I see he has answered. Jeff Armer Aug 18, 2023 It's not a ground issue, driver side headlamp grounds at same place (G201) underneath the dash . Headlamps The headlamps may be turned on two different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the OFF position, for automatic lamp control (ALC). During ALC, the headlamps will be in day time running lamp (DRL) operation in daylight conditions, or low beam operation in low light conditions. The LH HDLP and RH HDLP fuses, supply battery positive voltage from the under hood junction block to the left and right headlamps. The circuit continues through both low and high beam lamps, then back to the under hood junction block. The low beam and high beam circuits continue to the headlamp switch. The low beam and high beam circuits also provide the body control module (BCM) with both low and high beam inputs. The headlamp switch includes the dimmer switch and the flash-to-pass switch. When the headlamp switch is placed in the HEADLAMP position a path to ground is provided. Ground is provided at G201. Depending on the position of the high/low beam switch, either the low or high beam circuit will now have power and ground. G201 On the left side of the I/P, near the fuse block I found this, as Jeff says, not a normal ground near the light unit because it is computer controlled.

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

That is a lot of money spent on guesses. Nothing in that list of items you replaced would cause that, with the possible exception of the TCM (transmission control module) if that was the computer you changed? If the vehicle is running, it can't be the 'fuel pump, the fuel filter, all 4 coil packs, the spark plugs, or ignition switch'. Those are all involved with the car running and starting, and it does that, so why change them? Your vehicle is fully electronic and run by at least 3 main computers on a network. An auto electrician with a professional grade scan tool computer can scan the vehicle and diagnose all the systems in 20 to 30 minutes. It can even record what happens when the vehicle goes into gear. Diagnosis beats guesses every time and is far cheaper. https://www.google.com/search?q=mobile+auto+electrician+near+me This a video from yesterday that is the Legend of car repair, Scotty Kilmer. He shows a scan tool on a Ford Focus RS. It will give you an idea of a fraction of what they can do. ..

Have you made sure the engine will turn? Might pull the plugs and see if one of the cylinders might be full of fluid

No access panel on that year so you drop the tank or cut your own access point!

2.4L right? step #1 always unplug battery big NEG lug or blow up the huge fuses you will. lost the belt. if not draw your own? the service manual covers all this ,rent it (USA?) the schematic is here https://imgur.com/a/MUoyMqQ Dah belt is here.

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)
