Power window i have a 91 buick park ave and the passenger window will not operate and neither will the rear drivers side. I have replaced the metal fuse with one that i know works on the drivers front and passenger rear and it still does not work , so it seems to me that there is no power to the fuse block right there and thats where i get lost. I just bought the the car and the owner says they have put juice to the motor and the window went down , can you help me

You say the driver window works? wouldn't be a main fuse or fusible link then -driver door locks and window wouldn't work either. Each door has a module inside (computer) . The driver door has a circuit breaker power feed an a fuse DDM fuse 10amp located in rear junction block circuit breaker is located in under hood maxi fuse block. The circuit breaker also feeds battery voltage to the other door modules too. PDM - passenger door module fuse 10amp located in the instrument panel fuse box and the RDM - rear door module RDM fuse 10amp located in the rear fuse box - under the back seat.

Each power window is connected to a permanent magnet motor. The motor raises or lowers the glass when the door module applies voltage to the motor. The direction the motor turns depends on the polarity of the supply voltage provided by the associated door module. The 2 front doors have their own separate modules. The rear seat contains a single module, which controls both of the rear power windows.
A serial digital communications link, called the simple bus interface, is used for communications between door modules and the driver's door power window switches. The use of serial digital communications allows the use of a single wire to convey switching information between the power door lock switch and the driver's door module (DDM). The serial communication is also used in order to transmit switching information from the DDM to the other 2 door modules.
The door modules apply battery voltage of the correct polarity to the respective window motor when any local, or power door lock switch, UP switch is operated, driving the window up. Battery voltage is applied to the respective window motor in the opposite polarity when any local, or power window switch, DOWN switch is operated, driving the window down.

Driver Door Module (DDM)
The driver's door module (DDM) directly controls the driver's door window motor and the express down window feature. The DDM sends window UP/DOWN messages received from the power door lock switch to the passenger door module (PDM) and to the rear door module (RDM) over the simple bus interface (SBI) line. The DDM also contains a class 2 data link which communicates with the other vehicle system modules. The left front power door locks and the outside power mirror are also controlled through the DDM.
Passenger Door Module (PDM)
The passenger door module (PDM) controls the passenger's door window motor. The PDM controls the passenger's door window directly from the right front power window switch or from instructions over the simple bus interface (SBI). The right front power door locks and the outside power mirror are also controlled through this module.
Rear Door Module (RDM)
The rear door module (RDM) controls both of the rear door window motors. The RDM controls the rear windows directly from the rear door window switches or from instructions over the simple bus interface (SBI).

Power Windows
The vehicle is equipped with power windows controlled by the door modules. The Driver Door Module receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. 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.
If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.
Windows Power and Ground
The windows are powered by discreet power and ground circuits. These circuits are in the same dedicated connector as the window motor drive circuit .
DDM fuse 10amp rear fuse box , under rear seat !
PWR/WDO CIRCUIT BREAKER 30amp in the under hood MAXI fuse block .The fuse maybe blown but I doubt the circuit breaker would be bad . This is very complex I suggest you take it to a ASE certified repair shop or a Buick dealer .

Could be exhaust pipe support [cross bar].I had this problem.

Has there been a recall on them? Call dealership.

either the air duct under the dash is broken or diconnected, or you have a broken or disconnected vacume hose or line. unless you have seperate/digital controls for dr/pass air. if that is the case then you need to replace dr side control unit.

I remember replacing a lot of power window motors on Buicks,but not a lot of switches.Use a basic 12v test light to verify everything is OK to the motor.

my a/c blows heated air out on passenger side and cold on driver side what is my solution to this problem

Have you by any chance jacked up the passenger side, or got vehicle on a hoist to make sure there isn't any plugs on the underside that may have fell out? They could be round or oval metal or rubber plugs, probably in that area.

there YA go

Check the operation of the drivers blend door actuator. Sounds like its stuck or broken. Does the temp display on the dash flash?
