1996 BMW 525i electric car seats

The plastic tubes that house the flexible drives need to be shortened by about 8mm. One of the metal ends on the plastic tubes can be heated and removed and the plastic tube shortened and the metal end heated and reinstalled. I use a heat gun but have also used a cigarette lighter, be cautious with the open flame! Do one end of both tubes and the flexible drives come out when the work is being done, careful with them, they will be greasy.
