Arrow Windshield defrost mode mod

If you’re like me and you don’t want the A/C compressor running every time and all the time when you select the windshield defroster then here’s the solution. (The A/C comes on in defrost mode even thought the indicator doesn’t illuminate)

Pull out the HVAC bezel and behind the vent selector there’s a plug with two black/yellow wires, this plug automatically kicks the A/C on in defrost mode. Unplug it and it’s done!

If you need the A/C for defrosting then manually push the “A/C” button. In some conditions you need the A/C to defrost and sometimes you don’t, I’ve been using this mod for a few weeks and I haven’t needed it yet. The compressor really bogs down the SVT, and I'm saving some MPG.

I didn’t take a pic because I was in a hurry. I’ll credit this pic to “nomind” since I found it in one of his post. <---00-04 disassembly procedure.
