I was taking a friend's 74 BMW 2002 to the mechanic for him in the fall of last year. As I passed by Oak street on 49th I smelt some plastic burning. Then the smoke appeared from behind the dash and the front cowl area. I quikly pulled over and popped the hood to find the heater unit engulfed in flames. Seems the heater unit was siezed and overheated. I ran across the street to a residence where the ownwer was outside. I asked him for a bucket of water becaue my car was on fire. I wasn't sure he understood me because e was Chinese and didn't respond to me ote then ran away. I frantically looked around for something to carry water with. I found some type of plastic pail but the house didn't have any outside taps?? Then the owner came running out with a pot of water!! Saved the car, but not the heater unit. The car was getting a tune up prior to being shipped to Ontario to a new owner.
