1997 BMW 740i AC issue
My 97 740i has an interesting AC issue. Several months ago , the AC stopped working. I brought the car to some repair shop. They were saying there is some wiring issue, also replace the climate control head unit. It worked , but after a day or two, it stopped working again. I brought it back to the repair shop. They couldn't find out what is exactly the issue. But they reset the body computer, and it start working again. After several days, it stopped working again .., so on , and so on.
When AC is working , it blows ice-cool air. when it is not working, seems the ON signal doesn't reach the AC motor. The condenser doesn't turn ON.
Anyone has similar issue before?
