355 heater blowing cold

Took My 99 F355B out today and turned on heater. Nothing but cool air blowing out of it. This may be the first time I have switched it on, as it never gets cold in Miami. Would like to troubleshoot it a bit before taking it to the shop. Is there a fuse or relay I need to check first? Is this a common issue? I once replaced the heater core in a Buick but that was over forty years ago. Any advice/suggestions appreciated.

 

Did you turn off the "stop" button?

Also, does the recirculation flap close? That would stop fresh cold air coming in.

 

The Occam's Razor simplest explanation post goes to Dave. I feel like an idiot. stop button in wrong position. Thanks all.

 

John, I knew the answer for a reason, I too wore the idiot shoes with that button ;-)

 

lol here we go...

 

auxilliary or secondary water pump (can't remember which). In the front trunk, under the rear luggage space cover.
