Question about Cars & Trucks
Heater blows cold or hot air when it wants to. In between a drive, sometimes temperature goes from hot to cold / to hot. Turning off the engine then start the engine on again after a few menutes I may get lucky and get heat, but mostly I just get cold air blowing.

How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

There is a well known problem that is a manufacturer's defect with the soldered connection on the circuit board behind the temperature knob. There is a fix to re-solder the connections but the dealer will gladly take $450 to replace it with the same bad board that will last you a while. Look for the link to show you how to fix it yourself.
