Hello guys need help figuring out what this is and where it goes it’s on a 1978 Monte Carlo I looked on the wiring diagrams on my chiltons book but can’t find it anywhere!
Thank you so much bro I was going nuts trying to figure out what it was!It is a temperature switch. Wired into the low setting on the blower motor. When it is warm the low speed always blows with the key on, when it is cold it turns it off. Sorry didn't check the temperature just know in the summer it conducts and after being in the refrigerator for a while it does not conduct.
Not sure what the purpose was.
Pretty sure this is only on the early cars.
I have seen many of these on the cars but never found a wiring diagram with this switch shown.
Well i'll be..... my '79 malibu was doing the same, fan running on low with the key on, engine off when it was warm out during the summer time when i havent even touched any of the AC controls.It is a temperature switch.

Just unplug the thermal switch and it will stop running when you didn't turn it on. Everything still works just fine without it.Well i'll be..... my '79 malibu was doing the same, fan running on low with the key on, engine off when it was warm out during the summer time when i havent even touched any of the AC controls.
So i disconnected the ground wire from the fan itself from under the hood thinking something was screwy with the wiring since the the entire dash was apparently replaced from a different owner awhiles back with a clean non damaged one from different Gbody(MC).
I'm thinking this is a desert thing. Most cars I see were sold in the southwest desert. TX, NM, AZ, NV.I've never seen this in any car yet dispite all the cars I'ved crawled thru over the past 32 years looking for parts for my Monte.
