78 F-150 Ranger 460 w/ Factory Air........All was working PERFECTLY yesterday....... I parked it for about an hour or so, started it up, and NO BLOWER, NO A/C Clutch, both at the same time. The pnly common denominator I can plainly see is the FUSE (AGC35), which was not blown..... I changed it anyway, cleaned the contacts, and STILL nothing. WHAT'S UP HERE? WHAT am I missing??? The vacuum control switch/contacts are SPOTLESS, and even if they weren't, it wouldn't affect the blower...... NOTHING works. ANY HELP ???? Is there a relay I'm missing?? If so, WHERE is it located??
