I have a 2005 xc90. The problems started when the anti skid warning light went on. After that the passenger air bag warning light went on. The dealer fixed that, we thought. This still continues but now the whole dashboard goes out. Sometimes the windows, garage door and automatic door locks work, sometimes not. Obviously this is a big safety issue especially when you are not sure if your turn signals work or how much gas is left in the car. The dealer checks the codes but they have not had any luck. Has this happened to anyone else or does anyone have a clue to help? Thanks
