7747 A/C enable

[Brent Obermiller]

There WAS a message sent preceding my DUH comment which apparently is lost 
in CyberLand...But the short is: Steve's diagram is accurate except my 
signal to the ecm follows the high pressure safety sw.  I didn't see the 
explosion, so he could be right-The evaporator may have frozen, broke a 
solder joint, and then leaked as I only found the oil everywhere radially 
from the heater box, and no refrigerant. I will keep r-409 in mind but I 
converted another w/ 134a with no problem, and I can keep one kind on hand.  
Also I mentioned that I used an '88 Monte 4.3l Fuel pump relay for BOTH the 
fuel pump and A/C relay as I removed the redundant oil pressure sw. and so 
the A/C relay can serve as the Fuel pump relay in a roadside emergency.
