Could be your Body Control Module (BCM) has gone bonkers. GM geniuses decided their vehicles needed more computers on board. Most of your dash and interior switches and controls are routed through the BCM, a small mini-computer. Later models require reprogramming of these modules to the main computer. Not sure about your '97, you better check. Lights, wipers, turns-they all go to the BCM, before the wires go to the actual motors or bulbs. Not friendly territory for DIY'ers.

SOURCE: My turn signals, windshield wipers,

my guess would be the headlight switch. Either that or you could have a problem with your starter.

SOURCE: 1993 corsica--low beams work fine, no high beams.

Check the fuses under the hood...chances are it's one of them....there's not much left to check after that....check the fuses inside the car as well...it might be the high beam switch is bad that switches the low beams to high beams inside the car.

SOURCE: I have a 96' Chevy Tahoe, with the low beam lights

chances are! these are very problimatic and gm had an updated module for these wipers. i say that not knowing though if ANY aftermarket items such as radios, alarms, etc. have been installed and tapped into the harness coming from the steering column. think back to when it started(or at least noticed) and make sure this wasnt "professional" error. this happens alot and if caught ive personally seen a radio shop cut a $2100.00 check for repairs i had to make. cheers.

There's a wiring connector located below the battery box, you can see it better from under the car. Check to see if any of the wires coming out of the connector are green from corrison, if so carefully splice in new wire(s) to repair, this is caused from the drippage from the battery tray.

take a look at the dash ground wire located next to the right of ebrake release handle. if the bole holding the ground wire is loose, which was quite common it will cause all kinds of feed back problems, like described in the comments section to your question.

I have a 2000 328i and the wipers work when switched on (both low and high), but i cannot get the washer or intermittent features to work. I have water in the reservoir but i don't hear the pump come on. ...


Sounds like a defective multiswitch on the steering column that is used to turn on wipers, washer, intermittent, etc. If you were only having problems with the washer, I might suspect the washer motor. But the fact that you are also having problems with the intermittent feature, I would suspect the multiswitch. If you can get access to the washer motor, you can test it by putting 12V to the connector to see if the pump will come on. Are your turn signals activated with the same switch as the wipers?

Turn Signals and High Beams are not working and I have checked the fuse what else could it be? Everything else is working


Sounds like the combination switch is bad. The comination switch is for the turn signals and high beams and sometimes cruise control and windshield wipers. The combination switch is the turn signal lever. Also might want to check turn signal flasher operation.
