At first it was my radio. The lights would not stay on. Now, my a/c-heater will not always come on. When a/c does work and I have it on top and feet, cold will come out of top and heat will come out at feet. Now when the air works, the radio won't work. Can someone tell what possible could be wrong?

BMW's are famous for ground wire problems. Under the hood there is a clump of brown wires that attach to the body. Remove the bolt and clean the connection. Make sure all battery grounds are clean on the engine and the terminal is clean. Good luck
