rear defog/frost switch
 

got a bunch of these defrost switch i want to sell .what is the best way to test them before i sell them

Use an ohm meter.

Between the two tabs…

Off = infinity

High = really close to 0 ohms

Low = some ohms

If 0 ohms in high or low it’s bad. Don’t toss it though, it can be used as repair parts or repaired.

I would be interested in your “bad” ones.

Any chance you have any for the early grid style defrost? Like the one in the picture below?

have a bunch will send you photos

what about the tabs that have more then two tabs

You have any pics of the front/back of the ones you are talking about?

The one in your picture is the blower style.

what year car is the first photo of u

here u go

1970 blower style switch
 

How much for blower style 70 71 switch interested in 1 or 2 depending on price maybe package deal? Got a clean formula 70 bezel with defogg ,ac and rally guages

Those are later model with the grid style glass that uses a LED light. Notice the back of the one I posted has a tube that an incandescent bulb slides into.

I’m interested in the incandescent tube type and the On/Off blower style.

Not sure at the moment how to check the later ones out. Tomorrow I can get some out and check and let you know.

will have to test it and get back to u

I want blower style 70.71 like 1st puc with a red fuse. I'll send pics when I get home

Ramairnacho,

There are no fuses or lights on the blower style switches. The blower style does have a wire wound resistor (looks kinda like an old glass fuse). The lights are on the grid style.

Oh the long red tube isn't a fuse? I thought it was

Very old thread, but do you still have any available? I need the Hi Low, no light, for the rear defogger ( blower motor).

let me check for you
