auto temp II



I found the reason my fan would not work. The blower master switch, which is 
controlled by vacuum that is , in turn controlled by the cold switch on the 
bottom of the servo, does not work. Book says you need 8" of vacuum to make 
this switch and I had more than that at the switch and no contact. Now by 
shorting those two leads that the switch is supposed to make I have a 
functioning fan/blower. So I have to find a new vacuum switch. This one is 
green and it is located beside an identical looking switch(the yellow 
compressor switch)which, in turn, are mounted on the side of the "computer" 
under the passenger side dash near the vent. A word on that "computer". That 
is 1960 technology and there sure isn't much to this so called computer. I 
popped mine apart and found a dead diode along with a lot of dirt. So I will 
replace the diode and the vacuum switch and see what happens. The technician 
documents on the sight are an invaluable resource and I was also able to 
check and adjust my servo with instructions sent to me from a list member. 
Thanks. Maybe I will finally be able to get the air con working properly 
without spending lots of money. Anybody have a circuit diagram of the 
computer?
