PWM cooling fan(s) control using ECM

Other end of the connector looks like this;


I found it on the web, I dont have one. Looking though.

Thanks let me know, I found a motor with one on eBay, but kind of hate to buy a motor just to get the connector.

I didn't have any luck finding a new connector.

Thanks for looking, I bought the fan motor with connector on eBay, figured having a spare fan motor could not hurt.

When you get it, see if it has any kind of PN on it.

Have one here, this is all that's on it:

48769 4
PA6 GF15
PA6GF30

PA6 likely a reference to the connector material.

Aftermarket (crash part) mfg's are making replacement fan assemblies that come with the connector so someone has to be making it

I have figured out that there are many Mercedes Benz cars with similar PWM modules that appear to use the same connectors. That makes the search for used connectors a little easier but Mercedes also does not sell new connectors separately.

According to some threads on the Corvette forums there have been connector failures. Not surprising since they have to carry high amperage and are just spade terminal connections.

Since the end of the PWM module is conducive to potting, we are considering just soldering wires directly to the pins for the best conductivity and then potting with an electrical grade potting material.
