I feel your pain. I've been there and done that too. My last broken regulator occured when we were vacationing in Vegas. I used cheap duct tape that I bought from a supermarket to fix the left rear window in the closed position. My X5 sat in the sun for a week in 115 degree Las Vegas heat. The result was the glue on the duct tape baked onto window and door frame. It took an entire day to remove the glue residue.
