I have an 08 NITRO SLT. I have had the evaporator core and the AC compressor replaced. It has been properly charged with coolant. The compressor clutch won't engage. I have also received a engine code of B1032. That is the "evaporator temperature sensor circuit high code". I'm trying to locate the evaporator temperature sensor so I can check it. Please help.

It's located in the rear of the HVAC housing . It's near the bottom of the instrument panel on the passenger side. 2 prong plug.
Before doing any work on the Nitro, disconnect the Neg (-) battery cable and wait 10 minutes!
This will allow time for the airbag capacitors to discharge.
You don't want to have your airbags go off accidentally.
It has already happened to a few members here...

Will I have to pull the dashboard to get to it?

SM says you should, I don't think it is absolutely needed. But it will be tight. You will have to remove the glove box for sure.
Easy peasy, open the glove box, empty it, push the rear of the sides inward, rotate it more down, slide it sideways, and lift it off the hinge bar.

It may just be unplugged.

If it is plugged in, you can test it with an Ohm meter at the HVAC controls. This post will tell you how to remove the radio bezel to access the back of the HVAC controls.

A/C not been running, engine cold, heater core not warm from running engine.(The heater core is an open system, coolant runs thru it whenever the engine is running. Both when HVAC is on, as well as off. Same for A/C on/off.)

Key "off".
Ohm Pin 7 to Pin 8 in the 16 way plug. (These are direct connected to the Evap Temp sensor.)
Below are the range #'s. If you are hotter or colder in your area I can get more.
1800 ohms @ 95°F (35°C) Ambient air temp
2221 ohms @ 86°F (30°C)
2757 ohms @ 77°F (25°C)
3443 ohms @ 68°F (20°C)
4330 ohms @ 59°F (15°C)

You can also bench test the Evap Temp sensor itself using the above.

It is located in the EVAP box, behind the glove box. Remove the glove box an you will see it to the left lower side of EVAP box.

I'll have to look for it. I don't think mine is a problem but good to know it's location. Can't complain about 40 degree A/C when moving.

When I test mine, it only reads 1-2 ohms at 82 degress on my bar. I bought a new one today and it tests the same. Am I doing something wrong?

what's the part number on the sensor?

what's the part number on the sensor?

05143149 AA. It was cheaper at dealer than on eBay.

 

[2ndgen]

Is it problematic--should I change it preventatively?
I'm going to be changing out the evaporator and heater core, I could easily do it while I'm in there.

Some say it is, others not. It didn’t fix my problem so mine was probably still good. I think I either have a PCM problem or TIPM problem.
