Major power window problems. 2000 pontiac bonneville
I had this problem where only the drivers door power equipment works.
It is caused by a splice under the driver's seat. Spice #S302 where the
input from the drivers door module to the other door modules connects.
It is one of those cheap *** splice that should be outlawed. Moisture
gets in it and corrodes. Cut back the wires till you get the good stuff
and redo it the right way.
Splice S302 can be found under the carpet about six inches before where
the wires go up to the drivers seat. It is in a plastic wrap and tape.
I believe the wires for the window are brown and white.
Burnt out bulb in instrument cluster
I can't find the steps for it but I guarantee you all you would have to do is pull the cluster an replace the bad bulb....it is NOT that hard. Take a lot of pics if you have digital camera and you can do this. It really is not that hard....
One screw at a time and the whole assembly pops right out....very simple.
A/c stops and starts
Possible causes are a faulty blower motor, fan switch, resistor, or controller. Blower motor would be my first guess.
Water in floorboard front and back
My 2002 Bonneville had water problems soaking carpet and trunk area. I had it to the dealer twice, it was to expensive to go back a third time. I found 3 of the four drain tube disconnected midway down the roof piller posts. Probably from when the mechanic used air pressure to dislodge the plug. The front two were very challenging to get at to push the drain tubes back onto the connector. Why would they put the drain tube connection at such a poor location for repair is beyond me. The good news is no more water leaks since the drain tubes were reconnected.
