I want to check the operation of the evaporator temp sensor / thermistor but I'm not sure where to stick my ohm meter leads
Does anyone have a picture of where to test?
I'm guessing I'll have to disconnect the battery, disconnect the sensor, and test the resistance at the leads in some connector.
It should be about 2 kOhm and increase with decreasing temp (right?)
The reason I'm looking to test is that my a/c compressor doesn't ever seem to shut off. Even when I try to "freeze" the evaporator by recirculating and setting the blower fan to low. It's about 80-90F ambient now, so it's possible the evaporator never gets cold enough, but that's why I'd like to test. (Does anyone with a working A/C system notice the compressor turning off when the A/C is on?)
Thanks
