crank shaft

Hello, I have been searching for a blower resistor connector for about 10 years and cant seem to find one. My car is a 1970 cutlass supreme. I will try to post a pic.
Thank you, Mike

Ten years? It's a standard Packard 56 connector. Tons of them in junkyards, and you can buy them new, too.
You can get them new here.

Those same connectors were used on almost all GM cars with A/C for a large number of years.

I have been to junk yards, this one is different. All of the ones I found have the pins in a straight line. Mine has one turned sideways. If I could figure out how to upload a pic I will post one.

It's not this one, is it?

If your car has AC, then the connector is available at rockauto for about 5 bucks, which is the one Eric lonked to above.

No that's not the one, Mine has 3 pins that go sideways and one pin that goes up and down

MDchanic

Okay. I'm stumped, then.

You sure there isn't something weird about your resistor?

I will try to post a pic again, Here is the pic of the resistor,

MDchanic

Someone on here will have one.

Easy enough to let them know that you're looking for one that goes: | ||

Meanwhile, there's nothing wrong with using regular ¼" spade connectors.

Thank you!

Just post an ad in the Parts Wanted section.

Also John (2blu442) , Scott (oldspackrat), and several others are worth contacting directly.

I have that connector from a junk 69 AC harness. I also have a nice used AC harness too. $5 for the connector, or $25 for the used harness which contains that connector. Plus shipping.

I'm pretty sure that's the wrong plug.

His had four terminals. Yours has three, like a heat-only car.

- Eric

69442C

It's the correct plug. On 69 and 70, which use the same resistor he showed, there is a 3 wire connector and the 4th connector gets a single wire by itself.

Brian

MDchanic

Oh.

That's an easy one. From his description, I thought it was a four-terminal plug, which is a whole different story.

Does it look like this, then?



$1.65 a piece from Performance Connectors.

69442C

It looks similar to it but without dimensions its hard to say for certain if that one would work. The original plug does not have a locking tab on it but if the terminal layout was the same then tab would not cause an issue.

If he thought the original design was a 4 terminal plug, I guess that would explain the 10 year search.

Brian

MDchanic

Should be the same - all of the Packard 56 connectors are standardized.


If he was a stickler, he could cut the tab off with a razor knife.
It comes in black, too.


Sure sounds to me like he's looking for a single connector with four pins.

We'll see. Hey, Mike, you still here?

I can tell you with 100% certainty that the original design did not use a single connector over those 4 terminals. Even the CSM shows a picture that while a little hard to see, does show 2 plugs to deal with the 4 terminals. 68-70 uses the same equipment and I have restored a few 69's, both with AC and parted several with AC too. It's a 2 plug design.

MDchanic

Yeah, I saw the CSM illustrations, too.

I agree that two plugs makes more sense.

I've had 2 '68s and 3 '70s with A/C, and it sounds like what I remember through the distant mists of time.

Ok, I will check the connector on the car. I will post a pic.
Thank you,

I think 69442c has the right plugs. That resistor uses 2 plugs not one.

crank shaft

OK I feel like a real idiot. Eric I do have the gray one. I purchased this car with the AC stripped out 10 years ago. I located all of the parts out in California and had them shipped to me. Trouble is they packed the compressor with the evaporator core box and broke it. I called and they sent me another one and knowing the plug was melted I pulled the one out of the broken box and have been in search of the wrong plug for a long time, I'm sorry for the confusion. Now I don't know if the box is out of a 70, 71 or 72 Cutlass. Can anybody tell me if this is the correct box by this the connector.
Sorry, Mike

MDchanic

Okay, now it's starting to make sense.

The resistor you pictured below is from a '68 - '70 car.



The plug I pictured should fit it just fine, but not that one terminal that's hanging out away from the others, which gets a single terminal plug.



Just get a plug for whatever resistor fits in the hole in your evaporator housing.

Ok cool, I have the resistor with all straight pins None sideways, it would be the first pic posted. Sounds like thats not correct for 70. So Imay have installed a box for a later model, right?

MDchanic

Right. No big deal, unless you're the 100 point restoration type.

Ok cool, thanks for all the help guys. This is a great site.

You're welcome.
