Maybe someone else has experienced this.
When I have the AC in the Automatic mode sometimes on the interstate the AC will start blowing at a lower speed and a good deal warmer.So warm it feels like it not cooling at all. I can cut it off and on and it will start blowing and cooling like it should.So cool I have to raise the temp to 74 or higher for it to be comfortable on a 90 degree day. Now something else has started to show up.On start up with the AC in the Auto mode it will only blow through the floor and the defroster vents. I can restart the GC and play with the controls but it will only blow through the dash vents if I select the manual mode and it works fine. If I let is sit for about an hour the auto mode will work fine. The dealer can't reproduce it but it did it again today. Something else is strange, almost every time it happens the the unit reads 81Degress outside regardless what the outside temp is. As today when it was acting up it read 81,The correct temp was 94. After sitting for several hours it reads 92 the true outside temp and it worked as it should in the Auto mode. I have a Star Case started,and would like to get it fixed.
Please let me know if you have experienced anything like this.
I posted earlier about Erratic ATC. Posted today because it's doing something different. I just read the other post. I hate to say it but I'm glad someone else is having the same issue.Maybe we can it it fixed.
I started my GC about an hour latter and it's working fine. No rhime or reason why it does it. Taking the family away this weekend and I'm driving the other vehicle. Wife is just pissed that we can't take the GC because the Ac might act up. But I'm sure the dealer will get it worked out. But it's close to hell living with this and her not wanting to drive it. I am hearing I told you so or you should have bought this or that. I am in a position to just dump it but I really like the Jeep. Just wish we could find out what the problem is.
Mine did this once this past Friday for the 1st time, acted exactly like yours. I put it in auto and left in in the garage for a couple of hours and it started working again when I started it. Hasn't done it again yet but I'm just waiting on it. It appears to me the climate control temperature measurement stops functioning correctly and it gets into the wrong mode. It would work in manual mode though the A/C did not seem to be as cold even with it all the way down.
