1985 300DT...when should my electric fan come on?
 

I'm new to 123's...this is my first, and I have it about a month...it was very well cared for by the previous owner.

When is the electric fan supposed to come on? Mine doesn't seem to come on at all and my A/C is a wee bit warm...I suppose these are related?

This looks like an easy fix if the fan is bad (is there a way to tell if it's the fan and not something else?)...where can I buy one and about what can I expect to pay?

Thanks very much.

there's loads on this subject if you use the search

it would be quite normal for the fan stay off most of the time, it may be perfectly ok.

There is a temperature switch located by the a/c dryer at the pass. front under the hood. Not sure if the fan should come on without the a/c being on. If the system (a/c) is low, you're probably not going to generate enough heat at the switch to trigger the fan. Get the a/c serviced first, then see what happens, Paul.

As posted the fans ONLY come on when the A/C drier switch reaches 126F.
