AC Switch Rheostat Fan Speed Control

The year makes a difference, look like yours is a 74 or later? You can add you coupe to your signature easily.
You could be right. I have a euro 72 csi and just did an AC retrofit so the switch is from a different car but I got everything from one car for the retrofit. I believe it came out of a 73 cs…
Updated the signature…
Here's a solution worth looking into:

Improved AC airflow with 24 Volt blower fan
Hi everyone, In the past, I've had to replace the squirrel cage blower fan on my AC console twice as the bearings have gone bad. Replacement fans are difficult to come by and this had me thinking about finding a replacement fan/motor. It turns out that fan assemblies the size of ours are used...

Show us the plug to that switch please with clear wire pic.
It has four terminals so it is from a 74 without the heater fan bypass relay, the earlier ones have three pins. Does a 74 switch even work in an earlier coupe Don?
That’s a great question! I will try.
I’ll get a clear photo of all sides today
It actually looks as though there are 5 terminals, look closely.
I read this one several times, excellent write up. Not sure about others but for me in Miami, and especially with the higher than average temps…my limiting factors were the biggest condenser I could squeeze in, a Sanden 709, new W&N AC radiator, big Stal fan, shroud for improved airflow & running R12 which I can get. Yes, I could hang meat in the car and keep a Helly Hansen ski jacket in the trunk if things get weirder than that.Here's a solution worth looking into:

The fifth pin is just a mounting/alignment post. Yours should have three pins and that same post.
I may have one. Await complete images.
On standby…r
Looks factory , where did you source that switch? I wasn’t able to locate a suitable one that would fit. I love all the clever ideas, shortcuts and recipes here. I’d definitely buy one of those for backup but do want an original switch in mine @bavbob
Cheers,

the original switcheS were last produced in 1992 I believe.
I bought 10 in Egypt 5 years ago and haven’t seen anymore for sale since.
sounds like you have a 72 car with a 74 AC system so will need the later switch.

Don, where were you in 2012 when I could have used that nice repair for my Bavaria!
The Bav switch has a shorter threaded mounting post and will pose a challenge to mount in the e9 panel.
I am not sure if this E3 or E9. Does look shorter than the OP image. I will measure the post and ................post it!
