I have an '81 300td. The climate control fuse continues to blow. When the blower is off the system draws 1.54 amps. With the blower on low it draws 6.5 amps. On high it draws 15.84 amps. The blower out of the car with the fan still on the motor it draws 18 amps. With the fan taken off the motor and still 3 amps. with the blower in the car and all the air doors closed it will draw as low as 13.6 amps. Of course with the air in take closed no air blows out. Any ideas? Are there any resistors for the blower? Van
