Default wtb : Outside Temp Sensor (used)

I am looking for the outside temp sensor that is in the hose on the driver's side of the car. It is located behind the headlight. My climate control system has never worked right since I bought my car, and I now know why. My sensor is missing. I am not sure if this is the only problem with the system, so I am looking for a used one. The new ones are quite expensive. I am hoping to find someone parting out a car that wants the sell a working sensor at a reasonable price. It is for a 1983 US model. Thanks.

I should have one but how do I test it to make sure it's working? I'm off work today so I can check it later on.

I have a couple of good ones if IMo000 does not supply.

I just went through this exercise a month or two ago. When you find a used one, use a refrigerator to cool it down, then remove it from the refrigerator and connect an Ohm meter to the leads. If the value changes, the component is working.

$65 used.
I also have a new one - old stock - for $175.
Thats better than the $250 they normally go for.

I had a problem with the sensor not working on my former 86 5sp. What I did was simply replace the sensor with a resistor that registered in the middle of the range expected from the sensor. I figured this system was an over-engineering effort on Porsche's part to accomodate extreme climates. My temp control worked perfectly for 3 years after this replacement.

Brian, that's an interesting patch. The controller uses the outside temp to decide whether opening the fresh air vent will help or hinder the car's effort to get interior temp equal to the slider setting. It is likely most helpful in extreme climates, when it will keep the vent closed if it's too hot or too cold outside. Do you happen to remembe the value of the resistor you used?

FWIW, thermistors are hardly expensive components. Getting the right wiring connector is a bigger problem. If you have the old fittings and wiring and just need the right thermistor, you may find that repairing your old assembly is not a big chore.

Can't remember the resistor value off the top of my head, but I believe I used about 1.5K ohms
