Adding an additional heater core is also on my list. Do you have a build up on that anywhere ? I'd like to see what valves you used there.

Brian I use 22" wiper blades----love the larger swept area they give.
Relocating the nozzles on the wiper arms will put more solution on the W/S slightly ahead of the wiper on its upstroke. Instead of a wide spray originating at the cowl the spray pattern of my chosen nozzles will put more solution in the path of the wiper instead of flooding the entire W/S where it runs downward into wiper path. It's my general thought I'll use less solution but it being directed more carefully the overall effect will be better.
Not really had my solution freeze however the cowl-mounted nozzles become buried under snow and ice and unable to squirt fluid. Because the defrost function has no effect on them its either digging them out my hand or suffering through it all until the ice melts away. Arm-mounted nozzles along with a heated solution may eliminate this 3-month-a-year problem.
When this is finally put into action I will detail part numbers used along with a few photos. (Originally planned to do this over the past summer---time and interest ran out too soon. Oh, we who procrastinate.
)
Heated wiper park windshields have been with us a few years on different brands, differing degrees of effectiveness. They're basically larger more concentrated embedded rear window defogger grids. Naturally the more expensive brands like Mercedes, BMW etc have better results with these otherwise most are generally pretty pathetic; good idea, poor execution.
My aftermarket rear heater is somewhat elaborate and rather than clog this thread with its description anyone interested should begin a new thread somewhere here---not sure if in Interiors, Van Body or Home Builds. BTW by "elaborate" I mean there is electrical work along with coolant flow issues in order to have full control of the rear unit. As mine exists it can be fully isolated from the OEM heater core. As I understand it the Club Wagon versions have rear heater flowing coolant when the engine is running, IOW full time.
