What was the outside temp when you got the 35 low, 185 high side reading? Was the aux fan running anytime you had the ac on?

I did try the sniffer at the AC vents yesterday but wasn't getting any hits. That was right at the louvers though and I suppose refrigerant from an evap leak may be too diluted at that location. I will keep trying there.

The temperature was around 85 F when the 35 low, 185 high readings were taken. This morning the external temp. was 74 F and it was blow 40 degrees out of the far driver's vent, 50 out of the central driver's vent, 60 out of the central passenger's vent (I'm not sure about the temp out of the far passenger's vent because I couldn't reach that far while I was driving - but it was undoubtedly the warmest).

Yes - the aux fan does cycle on and off while the AC is on and the truck is parked.

Thanks for the feedback. Of course, no one ever wants it to be the evaporator, but if it is, I'd like to confirm it somehow before tackling that job.
