AC compressor non-cycling problem solved 200 1991

posted by  someone claiming to be Andrew on  Thu May 15 02:50 CST 2003 [RELATED]

Right, silly me

When I installed an electric primary fan in my car, I didn't bother to hook it up to the AC circuitry. Result? Right, compressor never switching off and the auxiliary AC fan running almost all the time (noisy as hell by the way). As simple as that - the AC radiator never had a chance to properly cool down because there was no longer a continuous air flow like with the engine-driven fan.
For some reason, it still doesn't cool as efficiently as before, but that's a different problem I guess.

Now, a question. I have a dual speed fan off a 960. What's the best way to connect: speed 1 (low) to coolant temp sensor and speed 2 (high) to AC compressor soolenoid or vice versa? The fan governor is so designed that speed 2 trigger always overrides speed 1. Now I have speed 1 connected to cooland temp sensor and it looks quite enough. Well, the engine runs a tiny bit hotter then it should but I think it's the sensor problem because the fan cycles on and off regularly.

What would you recommend?

Thank you all in advance
Andrew
