Hey
gprsdlyt,
That is exactly the problem we had with my wife's car 2 years ago; no heat on passenger side (cold air), sometime intermittent door operation by not changing modes, then fan motor quit. The whole thing cost me about $1300 to fix at a Jeep dealer...I think I got taken for a ride personally.
Mine right now has problem of working fine when system works, started intermittent then got worse, worked for a long time ok as long as I started car in mode I wanted to use. Then a few weeks ago the blower would go the randomly stop like it's in auto mode, last two days I couldn't get blower to work at all. Time to go in and get fixed.
Other than these two problems, both vehicles have been very reliable, just needing tires, brakes, oil changes etc. usual stuff. Hers has about 170K and mine has about 125K miles. They could be a little bigger but generally a good size.
