AC Wire ID help please - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Found this wire when I pulled the AC and heater. Can someone tell me is this just a ground wire? it runs from out on the firewall to inside on the side of the heated to a relay. the wire is gone and I don't know if the rats at some point in time ate the plastic off or what but I need to replace it. also as I was pulling off the heater box this spring fell down from somewhere, any ideas?

thanks
Keith

Well, that does look like a ground wire, as the wiring to the relay is a molded connector.can't say where the spring came from, never seen one like that.
HTH,

The wire is in bad shape. It appears to only go from the fire wall to one of the screws that holds the relay on

The spring belongs to the button switch on the diverter duct that connects to the heater box. I'm guessing the button switch was pulled apart.

The button switch is seen here on the duct.

Yes the button switch was apart and was getting replaced. Thanks Benny as you can see I finally pulled it. Once I finish getting the compressor and brackets bolted up I'll be giving you a call, probably later this week. Where do you get the boxes you ship the evaporate/fan assembly in?

Is that duct for sale?

F.A.A.benny · 12-15-2015, 03:34 AM

No problem, looking forward to hearing from you.

F.A.A.benny · 12-15-2015, 03:38 AM

I sold that duct last year. Just remembered I had a picture of it. If you need one I believe I have one or two good ones. Those things usually have the door broken more often than not when I find them.

We'll talk about it when I call

The wire is a ground for the high speed blower relay that you have pictured. Because the box it attaches to is fiberglass they ran it out and grounded it elsewhere.

yeah, that's the compressor switch on the diverter box.....
