My 1966 Grand Prix has this option. It worked well after I got the car (26 years ago!!) and after I had a new compressor and a few parts fitted.

It worked till about 6 years ago and firstly the heat failed but it still blew cold but a year or so ago, it all gave up the struggle. No heat, no cold.

So I took the car to an old mate of mine, an auto electrician who understands old GM A/C systems. He has it all working again but he says it needs a new intake manifold temperature sender.

I can't see one on the Ames website but they have a switch PM355 which has two terminals. Anyone have any thoughts on whether this sender will work in my car?

Thanks
