5FRYD4H81FB… MDX. 135k Brought in with complaint of touch screen “going crazy”. Drove home 40 minutes never reproduced it. This morning after 15 minutes of driving the radio / heater touch screen started to toggle between the radio and drivers temp control. Did this for 3 miles of driving stopped never failed again. Zero codes in any module. Screen is clean, all areas of the touch screen seem to work even when it was toggling it would let me exit back to the radio. It would just toggle back after. Just acts like the drivers temp control area is being touched. Is there a process to re-calibrate the screen? Don't seem to be able to get anything with my scanner. Have a compatible j-box & can purchase the factory tool for the day not sure if that will be any help though.

Are there buttons on the steering wheel that control the screen? Problem may be with the buttons or clock spring.

No HVAC control in the wheel. Only radio.

Have a look at TSBs 14-037 and 17-008

Yeah that might be the issue. They still have the update disks available.
