If Your Automatic Climate Control Is Acting Wonky

[quattroa4m]

If your ACC is acting wonky, you might want to check your inside temperature.

My inside temperature was 63 degrees on a 81 degree day, after the Grenadier had been in the sun for a couple of hours. The interior was warm, yet the ACC was barely putting out any A/C. Manually overriding the A/C worked as you would expect.

I rebooted the display/computer and the inside temperature came back at a toasty 105 degrees. The ACC kicked the A/C in full blast and the inside temperature started moving down...as it should.

So far, a couple of days later, the inside temperature seems to be working as it should.

Yeah but that issue is only possible if failure is limited to the AUTO mode.

Manual fan speed + temp should work

I just hate the double fan howl from the engine/bumper area at low speeds when the outside temps are high and the truck is moving slowly in traffic.
