Hiya. I recently acquired '99 AU Fairlane, 380km. Only just had occaision to use heater, and found it only blew air about ambient temp.

A/C works fine and blows chilly.

Is this a common issue? Is it likely just a little tap/valve somewhere?

Cheers,
T

hav u checked that the vacuum hose is connected to the heater tap?

Nope, a cursory glance reveals nothing hanging off anywhere, but im not exactly 100% sure where/what everything is.

All a bit different from my Cortina days! (That was the last time I did any mechanical work!)
