It's a tough one to pinpoint. Do an upper intake cleaning and clean the idle air bypass valve. Also clean the mass air flow sensors carefully.

Sounds more like a control valve is not working correctly.. probably stuck in one position because you should always have heat from your heater core...like when you chose fresh air or recirculated air...it switches a valve to allow the change...well from cold to heat there's a valve also that switches the vent inside dashboard

If you have a warranty, take it back and tell them to fix it. Right now, it's worthless. You paid to have it fixed. Why would you pay and then dump it?

You need to take some soap and put it in a spray bottle and be sure the system is charged and run the system and look for the leak. It works real well for finding leaks. Did you check the Schrader valves to be sure the leak was not there or a rub place on the bottom of one of the lines.

Heat light switch went bad or body control module.

Hello Steve,

From your post, "Finally had enough and stuffed a small block of wood between the driver's side bottom of the molded plastic linkage frame enough to lift the whole thing enough to put a moderate amount of pressure behind the wiper blade..", it sounds like this box is warped or somehow out of alignment. Is it possible for you to buy this box from a wrecking yard? Has you car ever been in a collision? If so the frame may have so un-repaired buckling resulting in the misalignment.

Sounds like a bad IAC valve. This will throw no codes and will also pass a smoke test.

Power Window assemblY Needs replacing. I've had to replace my driver side assembly a few times over the years in my 97 accord after a wreck on that side. Something doesn't line up right anymore and it eventually causes it to wear out. Steel cable and plastic parts don't work real well together over time- that plastic can wear out. Tricky part can be getting the door panel off. From there it can be pretty straight forward. May need an extra set of hands to get the window just right to attach to the bracket on the regulator assembly. May find some useful videos online, even if it's for a different car it can give you a good idea.
