Re: bypassing heater control valve and retaining heat.
you can just connect both lines with a pipe fitting. the only problem is hot coolant is gonna be running through your heater core all the time. ive seen a couple threads on this on the site.

Re: bypassing heater control valve and retaining heat.
just go to hardware store and put a brass gas/water valve on the line into the core, [ screw in brass hose barb ends ] only down side is you gotta pop the hood when you want heat or not.
My wagon is like that.

Re: bypassing heater control valve and retaining heat.
u cannpot just close off the line , that line also bypasses water around the thermostat to circulate the water.
take a picture were the heater valve hook sup and ill tell ya what lines to connect together to do it the right way, then in the sumer u can flip the 2 lines so u dont have hot water circulating threw the heater core when u try to use the ac
