Hey guys. I have bmw x3 3.5i f25 2011 year. Last 2 months I'm experiencing interesting problem that I can't figure it out. When i first start the car i have message on the CIC that windshield wiper motor malfunction will appear soon, steering wheel buttons don't work, radio works but I can't increase or lower the volume, ac doesn't blow cold(heat works), wipers don't work and I can't lock or unlock the car(alarm will go off). I let it run for 20 minutes and everything comes back to normal. If i leave the car for couple days the same thing will happen. I bought new battery from bmw and I'm still having the same problem. I noticed one thing, all od the above things are sharing one fuse, i checked the fuse it's okay. This is my family car and if I can't fix the car i will have to trade her in. Anyone had similar problem? Thank you
