Instrument Panel Problems of Volvo S40

Driving in rain, brake failure message began flashing on dash, then airbag failure. Slowed to a stop and turned off car, turned back on and drove slowly home. Messages continued to flash. Drove to service center and messages were no longer flashing , mechanic said it would need to be active to find problem. Same scenario many times since and the problem has become worse, driving down highway and messages appear then all gauges on panel fail and go to zero, windows fail, blinkers, brake lights fail, entire instrument panel went dark. Back to mechanic, he drove it same thing happened then stopped before returning to shop so could not diagnose. Extremely dangerous as several times driving in rain and in high traffic areas and on freeways with high speeds and then in construction zones bumper to bumper with no brake lights or ability to use turn signals. Has been out for five to thirty minutes at a time then appearing to work again before repeating the same failure problem. Never any warning, it just happens suddenly. To mechanic again, codes read and printed out pages of signal failures, none active at time so unable to determine problem. Check engine light has also appeared and when checked nothing active found at time other than pages of signal failures in system.

1. Severe summer thunderstorms and rain. 2. Drove approximately 1 mile and right blinker stayed solid green after turning. Drove about a mile further onto highway entrance ramp and car indicator lights flashed abs brake failure and air bag failure, then all car instruments (gas gauge, speedometer, tachometer, etc) failed for about five minutes. Instruments came back on but abs brake and air bag failure continued to flash for about 1 more minute. Drove directly to dealership. 3. Service department took the car right in and applied grease to the harness connector which should alleviate problems as they are known to get wet and corrode. Please note this is a 2006 model as I have read on the website that the 2004 model has the exact same problem. Additionally, driver side door locks and power windows intermittently inoperable leading up to this failure. Had a scheduled appointment to remedy this situation but brought the car in early as the car was inoperable without instruments.

Got a check engine light on and tried to get a full diagnostic test done, but the power control module was not communicating with vehicle.
