According to the book both those relays are getting ignition feed on the coil from the ignition load relay K127(C2007) no other relay involved, then when the swicth closes to earth the relay closes too.... it's the same for cooling fans and blower too

Electric troubleshooting manual, connector view C2007/K127(ignition load relay), you have to check on fan's and blower relay's coils(#86) for 12V with ignition on then see if they get ground from the switch on 85...if no 12V route a wire from the K127 power output to the relay's coils(86) cos maybe the feed is interrupted in a header or something cos K127 must send the voltage from F6 sattelite fusebox to both AC relay's coils
