any one know why my octy's air blower only comes on after the engine has warmed up.:confused:

it's a '99 1.6

No. Well not from that description anyway.

Do you mean the heater fan or the emissions one? And, if it's the heater fan, does the car have air con or not?

sorry, yes it's the heater fan and there is no air con:rofl:

poor or faulty connection on the blower motor?

:iagree: , well that or the switch on the instrument panel anyway. If it works from cold on some settings (probably the higher ones), but not others, almost certainly the switch.
