2000 Jeep Cherokee, 4.0, automatic, 4x4, stock.
Had the evaporator replaced about 2 years ago, work the first summer okay, last year it didn't. The compressor seemed to be cycling, so I figured maybe it was low on Freon. Bought a can R134 with gauge on it. The system read the correct pressure for what was stated on the can that it should read, so doesn't
seem to be a lack of Freon. Was reading on here about blend door problems, so this afternoon I removed the control motor on the underside of the unit, tried switching it back and forth by hand, seems to move easily. Didn't seem to make any difference with getting any cooling air out of the vents. Another dead end.
So I'm looking for other suggestions on possible problem. Been a good Jeep, except for the AC over the years. This is the second evaporator it has needed since we bought it used in 2003.
Thanks John
