Sounds like you've got add on A/C. I've got factory installed on mine and there are no extra switches for the A/C, it's integrated with the heater controls in the normal place. Both my 80 and my 81 S are set up the same. Tom -- Email problems to: scirocco-l-probs@scirocco.org To unsubscibe send "unsubscribe scirocco-l" in the message to majordomo@scirocco.org
