I am looking for a part number for the probe that goes into the evaporator core on a 95 Camaro. I have found part numbers for every other part of the HVAC system except this one. Will the A/C work without this part or is it necessary?

 

Probe??? Dont know what your talking about??? This is the engine pic of A/C system in engine bay, thx to Shoebox , http://shbox.com/1/ac_system.jpg , but I didnt see the inside pic for the A/C heater module assembly ..

I have a CD with this picture and I dont see a probe... Location of part??

 

Is it the cycling switch (also referred to as the temp. sensor) that you are after? It would appear as a "probe" with a wire lead on it?? In the illustration it is located right in front of the evap. air filter. Part # for it is 52458970...hope this is of some help.

 

It is in the box. It has a blue, gray and a black wire. It is placed in the fins of the core to provide a temp reading for the PCM. It is listed as an "A/C evaporator temperature sensor". I have the pressure switch on the line. I am wrapping up my A/C system for Summer and I want to cover my bases.

 

Okay, that is definitely the part # I gave above. I have no idea if you need to have it or not, though...hope this helps.

 

I will look into that part. I might hook it up and see if I have to have it. If not, I won't bother with it.

 

Sholt c33 is right...... GM PART # 52458970
CATEGORY: All
PACK QTY: 1
CORE CHARGE: $0.00
GM LIST: $47.10
OUR PRICE: $24.49


Looking at my GM CD its under Group 9, 1993-1995 A/C heater module assembly, part # 44

I think you might need it for the AC to function properly..

 

I am expecting to need it. This is a swap and I want everything working as factory as possible. I currently have it running through the third gen pressure switch without a relay. I want to take some of the load off the electrical system and let the PCM control it.
