				Heat flappers connections, disconnect?
			 
 
			Hi.  I have an 83 911SC with manual heat controls and delivery of unwanted heat.  I know my heat flappers are rusted out and need to be replaced.  Although the downward facing vents are wide open, I can see that the inner values are not fully closing. In order to get thru the summer,  I've disconnected the hoses at the ex-changer end and not the flapper end.  Does anyone out there see a problem with this?
