1999 deville

[Cal]

my Deville has an electrical problem where the driver and rear passenger
power windows quit working (independently) for days and then kick back in
again and works now. They did not quit or start working together although
their was a few days where they both weren't working at the same time... I
replaced the master switch a year ago and every thing worked great till
now.. also fuel gauge hasn't worked in years.... not sure it's related
though... 2 years ago the car killed on an off ramp.. but started right
away... and it never happened again... is it possible it's the BCM for all
of this? or are all separate problems?

Thanks...

Well on the issue with the doors under the master switch you have a
black harness that holds all the wires together and sometimes they
all one comes loose and it needs to be pushed back into place. If the
button doesn't make a clicking noise when you push it its broke or if
you don't hear the motor in the door its the motor. On the fuel is the
display broken or it says "E" all the time if the display doesn't work
period then its the display and its a easy change out. If it says E
all the time then your fuel sender unit is broken and you have to drop
the fuel tank and put on a new one. I would recommend going to the
shop on this based on your working with flammable stuff
