Agreed. I've been following the process I described for the last 34 years with great success.

Directing air to the windshield would be a good idea if it didn't also run your A/C in the dead of winter, and blow freezing air over the heater core on a cold engine.
Blowing recirculated, non air-conditioned air on the windshield would be great, but our cars don't allow it. |

I completely agree that letting the car warm up a bit before turning it on defrost is a good idea, 'cause otherwise you are just pushing cold air through the vents, and at the same time loading the engine unnecessarily with the AC compressor, before it has warmed up. I don't wait until the blue light goes off, but I do wait until warm air is available. |

My GSR'd CRX had no AC components in the car. It was nice being able to run the front de-fogger without the engine taking a strain on those soggy, humid evenings.

In this scenario:

The windshield only needs to be brought above freezing for the ice to slide off, which is easily done with a warm interior regardless of which vents you use. It's amazing how much faster the interior warms up when you're not running the A/C and pumping in winter air. |

Just installed the subaru remote start today. Only took 1hr 15min and cost $285 and $45 to get programmed. Much better than paying $600 for dealer to do!

Oh, and the a/c clutch is literally one wire on top of the compressor, it would be very easy to add a switch in the cabin that would disconnect it, then you could run defrost w/o a/c engaged. I plan to do that in a few weeks
No codes or ill effects I have seen with the wire unplugged (required for evap cleaning) |

Found another thing my wagon likes to do today.. Mud trails.
Was driving through a local park this evening and found a side road/trail. Presumably for work trucks in the park. I followed it. After a building, the gravel part ended and the muddy trail kept going through the woods. I followed it. It was flat, so no incline or decline, but it handled the sloppy, deep-ish mud crazy well. Even on Turanza 215/45 touring tires. No hesitation. It rained like hell all last night into late morning today, so it was fresh. Probably a couple inches worth of soggy mud. Now to just get a taller side-wall set of tires and some Rally Armors. There was dried mud slung around the wheels, f/r fenders, and caked in the wheel wells when I got home. lol I find something to love about my slow wagon everyday. |

I think when the defog/defrost mode is selected the recirculation is disabled. Maybe it is different for cars with auto climate controls?
This discussion is now activating deja vu, as we already discussed the pros and cons of AC, Recirc. and how they work within the defrost mode, or not as the case may be. |

like i said though i do plan to wire in a disconnect for the a/c clutch so I can run defrost mode w/o the compressor running. plan to just do a test first to see if it really works well that way or not. |

just looked at wiring diagram, from what I can see the wire that goes to the compressor is the only one that goes to it, there is no way for the computer to know if it is actually egaged or not. I will be wiring up a disconnect switch in the near future for it
for my "fun" switch, i ordered a pack of 10 mini rockers for 3.95 total, and I will have 9 left over, so I might as well use one of them for this purpose |

Flyboy, you may want to include a freewheel diode or resistor to absorb the inductive kick of the compressor's clutch. Otherwise you may get some nasty high voltage arcing between the contacts on that switch.
If the computer really wanted to know, I'm sure it could measure draw on the clutch line, or monitor the pressure switches, but I doubt it cares much. |

I know it's been covered somewhere. Did a "search", and it brought me back to this thread.
Can someone do a quick synopsis of said "fun switch"? An appropriate link would also work.. |

Car covers will help in that regard. The ice doesn't stick to the cover and breaks as you lift it. It was about 60* yesterday and then sometime near sunset the rain stopped and a cold front came in. I started this morning finding beaded frozen moisture on the INSIDE of my window. Little droplets from condensation. near the bottom center of my windshield. (from where my phone holder is attached to the window and down). --kC |

When I get around to this, I think I'm going to attack it from the HVAC panel and free up the recirc function as well. |

i would like to do it that way, but I'm not sure how with the manual controls that I have. need to check the wiring diagrams more.

I know with my remote start and auto hvac the car senses the outside temp and turns on rear defrost, mirror and wiper defroster automatically. The light is not light up on knob but you can see the rear defrosting. Don't know if the manual hvac does this too. This is only for oem remote start. Aftermarket remote starts with the option for an extra channel can be programmed to do this too or crack windows in summer.

SIA_worker, does your engine shut down automatically when you open the door?

Yes but with coupon codes and getting it for $285 and $45 to program it's nice to retain factory simplicity. Single button aftermarket allow car to run but have to unlock with key because keyless buttons are disabled while engine is running and with factory you get auto defrost on rear, mirror, and wipers. Plus you get confirming that car started. Sure for price dealer charges go aftermarket, get longer range, added security feature, and ability to do much more but for the price I got I can't be happier.
