Long story short, I bought a 2010 Rogue salvage title that has been rebuilt. I bought in February, with -20F ambient temps. So I did my best to determine if the AC was working, checked for pressure in the low pressure line, and felt that it was OK.
It was not.
Discovered that the compressor was completely seized, so yesterday I changed it out with a new unit from Rockauto, filled with oil, and recharged the R134a with 1.11lbs.
AC still not working. I did test the PCM, turn key off, turn key on, press door switch 10 times, turn key off, turn key on. And it went through the cycle of the headlights, wipers, fog lights, and the AC compressor clutch. Clutch definitely engaged, so compressor is working. YAY!
But still no AC. So I did some sleuthing around, and discovered that there is a plug dangling beside the horn in the grill, and based on experience this would be where the ambient air temp sensor would go.
I do not have Auto-AC or an external vehicle temp readout.
Is the Ambient Air Temperature sensor required to ensure the AC system will engage?
In any case, I've got a sensor on the way and will pick up and plug in after work to see if it gets me some AC!
Thoughts?
