More of an annoyance than a problem.
I have a 04 WJ Laredo 4.0L Selec-Trac. The issue is that when I have the vents on the Chest/Floor setting at any fan speed. I give it half throttle and the vent changes to defrost. When I let off the throttle the vent returns to the correct setting. I am not sure if it is a electrical issue or just working as designed. Any ideas would be greatly appreciated. Also does anyone else have a very minor rear main seal leak. It is so small I was told to leave it alone. I have 122000mi on the clock.
