After a little detective work I beleive I was able to find out why my washer fluid light keeps going off even though my washer fluid is full. There are two wires (one blue and one brown) going into the sensor and the brown one was cut. I haven't had time to reconnect it but I would think that this would set off the sensor don't you think? As far as my obc is concerned it must be the back light bulbs are burned out. At night I can't get any read out and I pointed a flashlight to it and the clock appears fine. Dimmer switch I still have no clue why it does work but someone had installed a radio and radar detector so maybe they hit or cut the dimmer switch wire or possibly my switch is bad. Any suggestions on the dimmer let me know. Thanks.
